Both the South Skunk and central Des Moines River Valleys formed between 12,000 and 14,000 years ago as meltwater outlets of the Des Moines Lobe  of the Wisconsin Glacier. As the glacier advanced and subsided, meltwater was released into outwash streams that flowed from the ice margins. The upper South Skunk valley (above Ames) was formed along the margin of the Altamont advance, which produced the moraines, kames, eskers and kettle holes such as those in the Ioway Creek Watershed near Bjorkboda Marsh in Hamilton County and the prairie potholes at Doolittle Prairie near Story City.
The Des Moines Lobe region (Ecoregion 47b), having been impacted by the most recent glacial advance into the state, is among the youngest and "least developed" landscapes in Iowa, meaning that it is not as well drained. And though the Skunk River Valley and tributaries are not as deeply incised into the landscape as the Des Moines, the Skunk is actually thought to be an older drainage, and the wide valley, terraces, and sand and gravel deposits reflect the size and power of an older glacial river.
Locally, the Altamont advance extended to the area of Peterson and McFarland Parks on the Skunk, to just beyond E18 on Ioway Creek, and to the Fraser area on the Des Moines.

Although estimates vary, it is generally agreed that approximately 99 percent of the original wetlands, marshes, and small streams of north-central Iowa (the Des Moines Lobe) were drained and plowed, while the larger streams and rivers were dredged and straightened to facilitate removal of surface water.
The South Skunk was straightened from Ames to Polk County in 1893. (See 1898, 1899, and 1902 maps at Additional Links (History).)
Today, artificial stream systems replace the more absorbent wetlands and marshes, and these streams flow in direct contact with Iowa's vast agricultural landscape. Further, we have eliminated many natural stream meanders through straightening and channelization. Drainage of wetlands and channelization of streams and rivers have promoted a hydrological imbalance. Today, in the upstream or headwater portion of small streams, water moves off the land much faster, allowing greater stream bank and bed erosion, creating increased transport and deposition of materials (including soil and agricultural chemicals), along with more severe flooding downstream. Draining of wetlands has lowered the water table, causing natural underground springs and small streams to cease flowing and shallow wells to be deepened. Most of these changes in surface and subsurface hydrology have occurred within a human lifetime.
The Skunk doesn't boast scenic 300-million-year old Pennsylvanian sandstone bluffs and canyons such as those along the Des Moines at Red Rock, Ledges, Dolliver and Woodman Hollow. An uplift of older Mississippian limestone protrudes into Northwest Story County (Bedrock Geology, IGS) and these bedrock outcroppings are visible along the river at and above the US Filter dam.
Martin-Marietta's Ames Mine is said to be the largest single producer of limestone in the state, and is one of only eight underground operations. The Ames Mine takes limestone from the Gilmore City Formation and from the Eagle City & Maynes Creek members of the Hampton Formation , named for their outcroppings to the northeast. These formations are good water-producing aquifers, though Ames municipal wells draw from a shallow alluvial aquifer which overlays a gravel-filled pre-glacial valley.
Ancient River Channels


The Midcontinent Rift, Iowa's Almost Ocean
One billion years ago, the Earth's crust split across part of the North American continent. This tear, known as the Midcontinent Rift System, extended for 950 miles from what is now Lake Superior Southwest to Oklahoma. Rocks produced during the rift's formation can be seen today surrounding Lake Superior, including basalts along Minnesota's North Shore and sandstones along Wisconsin's Bayfield Peninsula.
 
Midcontinent Rift System in Iowa
In Iowa, the MRS are dominated by a huge, uplifted block (called a horst) of basalt that follows the axis of the rift across Iowa from south-central Minnesota to southeastern Nebraska. A couple major structural features along the eastern edge of the MRS, the Perry-Hampton Fault Zone and the Thurman-Redfield Structural Zone, pass through Story County just North and West of Ames.
(The rocks of the MRS are buried to a depth of 1,200 to 5,500 feet, but must somehow account for the deep connection some of us have to the waters of Lake Superior!)

<![CDATA[Historical notes along the Water Trail]]>Sat, 17 Dec 2022 19:02:03 GMThttp://skunkriverpaddlers.org/blog/historical-notes-along-the-water-trailCURRENTLY UNDER CONSTRUCTION!
This collection of information is being revised and updated from an earlier version of the SRP website. Suggestions and helpful criticisms may be left as a comment.

Native Americans called the river "Chichaqua", which meant Skunk or "smelly place". Some believe the river was named for the odorous wild "Skunk Onions" (or Skunk Cabbage, Symplocarpus foetidus) which once grew along its banks. Being the first green plant to appear in the spring, it was sought by both Native Americans and pioneers.

The land that today is known as Story County was originally prairie, with the exception of some groves along the larger streams in the area (map). It was also home to various native tribes and nations including the Ioway and Meskwaki. The first European inhabitants in Story County came mainly from Indiana, New York, and Pennsylvania. Later, many Norwegians, Germans, and Danes came directly from overseas and inhabited the area. The first large population influx occurred during the 1850s.   (www.storycountyiowa.gov)

Much of the following information is taken from A History of Story County, Iowa by William G. Allen, 1887, and  from History of Story County, Iowa by William O. Payne, 1911.

Story City
Originally called Fairview, Story City owed its growth, if not its initial settlement to the arrival of the railroad & Norwegian immigrants. Before the Norwegians moved into central Iowa & the Story City vicinity, American settlers had begun to farm in the area by the mid 1850’s. They then preferred to live near the Skunk River (then called the Chicaque) because it provided ready access to water & timberland which surrounded its banks.By the 1860’s settlement activity quickened. Norwegians who had first come to Illinois from their native country in the 1850’s found land in Story County both inexpensive to buy ($1.25 an acre) and profitable to farm. American farmers & merchants followed the Scandinavians.


The first water power saw mill was built by Mr. Brown northeasterly of the artesian well. It sawed but little for want of water power. The early history of Howard and Lafayette, to be found elsewhere, will give further items of early times, (see R. W. Ballard's letter.)   (Pages 66 and 189 W.G. Allen, 1887)

Sowers Pioneer Cemetery sits on a high bank, river-left, approximately 0.7 miles below the dam in South Park.

Long Dick Creek
One of the earliest settlements in the county was made on the east side of Skunk River in the northern part of the county, by James Smith and his sons, Robert Bracken and his sons, and Joseph Brouhard. James Smith built a mill on Long Dick Creek, about 1/2 mile north of it's mouth & near the center line north and south of section 18, township 85, range 23, and only a few rods north of where said line crosses the creek. Smithfield (an old recorded village, but now defunct) was a very short distance north of the mill.   (Pages 54 and 66 W.G. Allen, 1887)

Long Dick Creek was the site of the first school of the Sheffield(?) settlement (edit - view source).

Long Dick Creek received its name from the incident of a man, by the nick-name of "Long Dick," in looking over the country, up and down the creek, got lost and had to stay on the prairie one or two nights — yes, and just think of it — among prairie wolves and Indians — the Indians one hundred miles away; why, it was terrible! Well, he finally got back to settlement as Long as ever; so the creek was named "Long Dick" (Page 183 W.G. Allen, 1887).
E18 Access
Anderson Access
Anderson Access was formerly known as the Anderson H-Tree Access for a naturally grafted pair of elms, an American and a slippery (red) elm. Dutch elm disease killed the American side, then the slippery side by the mid 1970's. (1908 photo, R. Schumer photo, 1980 photo - Farwell T Brown Photographic Archive).

The steel high-truss bridge at Anderson Canoe Access was moved from it's original location on the Lincoln Highway in 1949. (Ames Historical Society photos taken at Lincoln Way)

The American Legion's Forty & Eight Cabin is river-right just below the bridge. The Forty & Eight organization draws its origin from World War I when young Americans were sent to France to fight a war to end all wars. The narrow gauge railroads of France had boxcars (Voitures) which were used to transport the men and horses to and from the fighting fronts. On the side of these little boxcars was stenciled the capacity of each, holding either forty men or eight horses, and these voitures became the trademark of the organization. Membership in the Forty & Eight is by invitation only for recognition of service to the American Legion and/or its programs.   (fortyandeight.org)
The greenbelt trail that goes north from the Anderson Access follows what appears to have been a northward extension of Pleasant Valley Road (see Lafayette/Howard Township maps at Additional Links). That road crossed the Skunk in the first section and connected with what is now 140th Street. Some portions of the trail are through lands that were formerly acquired for the I35 corridor.
Bear Creek Bear Creek enters the Skunk about 1 mile above Sopers Mill. It received its name from the circumstances of a black bear having been killed on it by Isaac Smith, one of the early settlers. (Page 183 W.G. Allen, 1887) Upstream are the Bear Creek Riparian Buffer Demonstration Sites, an EPA National Restoration Demonstration Watershed.
Soper's Mill
Soper's Mill stood on the east (south) bank in the area of today's bridge, and during low water remants of the crib dam are still visible on the stream bottom. Historical accounts vary, but the original mill was reportedly built in 1856 by Thomas Hughes, and the Hughes sawmill rebuilt as a gristmill in 1859 by T. K. Soper. It was remodeled again in 1871 and at that time began producing a flour know as "Soper's Superlative". By 1887 mill operations had apparently ceased, and in 1909 the mill dam washed away. The mill was torn down in the 1930's and walnut lumber from the structure was used to construct a barn which still stands nearby. (HISTORY OF MILLS, W.G. Allen, 1887)

The concrete abutments upstream from the bridge are the remains of an 1876 iron Rainbow Truss bridge, which before washing out in 1996 was on the National Register of Historic Places. The existing bridge was built in 1939.
Soper's Mill on the Skunk River - "1870's photo", "1880's" photo, Farwell T Brown Photographic Archive. The house in the 1870's photo is reportedly that of P. J. Swearinger, one of the later operators of the mill, and it may be the foundation of the Swearinger home that is still intact just up the hill.
Old Iron Bridge at Soper's Mill in 1914 (Farwell T Brown Photographic Archive).

The Soper's area has long been used by the public for recreation and was a regular camping spot for Scouts (photo) (Farwell T Brown Photographic Archive).

Canoe access at Soper's Mill is approximately 1/4 mile below the bridge at a constructed rock riffle. The riffle was initially established in the 1970's and was rebuilt in 2006 with a state Fish Habitat Grant. Just downstream and at the end of the Soper's area a steel pipe lies across the river. The pipe may have once capped a small wooden dam, and some verticle 2x6 boards are still visible near each bank. There may also have been a ford crossing here in pioneer days (see Milford Township/Story County maps at Additional Links).
Keigley Branch
Keigley's Branch empties into the Skunk River a short distance below the Soper's mill area. This creek was named for John H. Keigley, who settled near it in early times (Page 190 W.G. Allen, 1887). Keigley Branch follows the interior margin of the Altamont glacial advance (see Geology), and downstream from Keigley's Branch on river-right there are a series of spoil piles and scattered glacial boulders from a 1930's rock quarry.
Franklin TownshipFranklin Township includes the area between 160th Street and East 13th Street, and from the Boone County line to Dayton Avenue. It includes Hannum's Mill and the early town of Bloomington (see maps at Additional Links).
Franklin Township is a township of much good land and is being settled and improved rapidly. At one time it had, and may have yet, more native timber in it than any other township in the county. It contains several streams of water along which timber in earlier times was quite abundant. (Page 193 Franklin Township Description, W.G. Allen, 1887)
Franklin Township is the best township for quarries. There is a good one on the west side of Skunk River on the southwest quarter of the southwest quarter of section 13, township 84, range 24.
- Quarries are found on sections 23, 25 and 26. There is a pretty good one about eighty rods east of the west quarter corner of section 23. Near the center of the northeast quarter section 26, and elsewhere in sections 23 and 26, township 84, range 24, quarries are found. It is thought there is a very good one on the southeast quarter of section 26, owned by Pressly R. Craig.
- It is understood there is a quarry on the east half of section *32, or the west half of section 33, probably in the northwest quarter of section 33, township 84, range 24, is more definite.
- In Milford Township there is one or more quarries in sections 6 and 7. At or near the north quarter corner of section 7 (and at Soper's Mill) there is rock, and up the river sixty or one hundred rods north or northeasterly from the mill is the Sowers quarry; or it may be about 100 rods northwesterly from the Pleasant Grove church.
- We find also a fair quality of rock in sections 28 and 32 on Bear Creek in Howard Township.
- On the northeast quarter of the southwest quarter of section 13, township 85, range 22, there were many years ago many large and beautiful white lime rocks which made a singular and delightful appearance. Twenty-five years ago they were visible for miles; but time and other mishaps may have robbed this lovely spot of much of its beauty. This beautiful group was miles from timber. (Page 389, Stone Quarries, W.G. Allen, 1887)
Bible Creek is the little stream that enters just above the Hannum Mill/US Filter Dam. Bible Creek got its name from the circumstance of a book pedlar having left his buggy, loaded with books and Bibles, in a snow drift which proved, when the snow melted, to be in this stream.   (Page 193 W.G. Allen, 1887)

Ames Lake
A 1970's Army Corp of Engineers Flood Control Proposal known as the "Ames Lake" would have flooded about nine miles of river bewtween Ames and Story City. The dam would have been located in the southern part of Peterson Park and the "Native Prairie Area" along I35 (North of the South-bound rest stop) was originally planned as a scenic overlook. (More USACE projects at Water Resources Development in Iowa 2004)
Hannum's Mill(Also known as "Miller's" and the Franklin Mill, and today as the US Filter dam)Large timbers, "cribbing" from the original rock crib dam, still project downstream from beneath a concrete cap. A limestone bridge abutment, probably part of the old Marietta Road (Marietta being the former County Seat of Marshall County), still stands river-left near an old USGS gauge house. The bridge was torn down by W. P. Coon in the early 1900's after Marietta Road relocated downstream to the new "red bridge". The lumber from the bridge was used by Coon to construct a barn on his property south of the river. Barely visible near the north bank, the date "1948" is sctratched into the concrete surface of the dam, and that is thought to be when the original USGS gauge was installed. It has since been replaced with a new guage at Riverside Road.
Hannum's Mill (Miller's in earlier times,) situated on Skunk River, on the west half of the southwest quarter of section 23, township 84, range 24, was a water and steam power mill, and did a great deal of work as a flouring mill and corn grinding. The main mill was moved in the year 1882 to Odebolt, Iowa. What was left of it is not of much value compared with what it had been. It also did considerable sawing as there was fair timber near by.   (Page 385, HISTORY OF MILLS, W.G. Allen, 1887)

Crib Dam construction, from FRONTIER MILLS BY GEORGE C. DUFFIELD in Annals of Iowa Volume 6, July 1904, No. 6: The mills on all the little streams were almost alike, the difference being in the dam, the wheel and in the fact that some were only saw mills, some grist mills and some saw and grist mills combined. In describing the Clayton mill, I will have described all the rest, except where I note differences. The Claytons felled trees on both sides of the creek, cut them into the longest logs possible, hewed them on two sides, and laid them end to end, spliced and pinned, clear across the creek on bed rock. Three or four such lines laid down; two or three feet apart, notched every four or six feet and cross ties laid in and pinned, made the foundation frame. The pens thus formed were filled with clay from the hillside and stone from the creek-bed. This was the start, and with two more lines of timbers, notched and laid down on the ends of the cross ties, and over the outside timbers of the foundation, then other cross ties, and more long timbers, formed a row of cribs, and gave the dam its name of "crib dam." It was raised some two feet higher at the down-stream side than the up-stream. The cribs filled with stone and clay, and roofed with plank, or logs finished the main part. To prevent the back wash from undermining it, there was a row of secondary cribs built along below and pinned to the main dam. This, filled and roofed like the main dam, the roof slanting from a couple of feet under its comb to a few inches of the bed of the creek, was called the apron. The whole structure was 14 or 16 feet through, 8 or 10 feet high and some 60 or 65 feet long.

Town of Bloomington
Ada Hayden ParkAcross Highway 69 from the Sleepy Hollow Access is Ada Hayden Heritage Park, a former sand & gravel quarry purchased by the City of Ames in 2002. The property was acquired in part to preserve its use as a backup source of water in times of drought.
Ames' water is supplied by 19 wells in 4 wellfields, each drawing from shallow deposits of sand & gravel hydraulically connected to our surface waters. Water levels in these wells are affected by streamflow in the Skunk and Squaw. In the midst of a severe drought in 1977 and under the advice of an ISU hydrologist, a temporary dam was constructed at North River Valley Park to impound the flow of the Skunk River, allowing more water to infiltrate into the aquifir. Additional water was pumped to the river from the Halletts Quarry (now Ada Hayden Lake) to augment the flow. The effort was successful and water levels in downtown wells were restored within days. The temporary dam washed away later that summer but was needed again and rebuilt several times in ‘81 and ‘82. In 1983/84, a permanent concrete dam was constructed to provide ongoing well replenishment. Water was again pumped from Hallett’s in 1988, and from East Peterson Park in 2000.
The hydraulic relationships between Ada Hayden Lake, the Skunk River, and the shallow aquifirs from which Ames draws its water supply are still being studied. See Groundwater flows in and out of Ames' Ada Hayden lake and Buried Channels, Quarry Lakes, Beaver Dams, And the Water Supply of Ames, ISU Department of Geological and Atmospheric Sciences.
See the Ames Drought Contingency Plan for information about water conservation measures and the drought conditions which would trigger use of water from Ada Hayden Lake.

Archaelogical explorations and investigations of the Skunk River valley performed as part of the Ames Lake proposal revealed what may have once been a "buffalo pound". Bison bones had earlier been discovered in a boggy area along the edge of the floodplain northeast of River Valley Park, and it was suggested that bison were driven or guided into the area for slaughter. The use of a natural hollow to corral and capture (impound) a herd of bison was one of several hunting techniques employed by Native Americans.

SE 16th St
ChannelizationBeginning in 1893 the South Skunk was straightened from Ames well into Mahaska County (photo, Farwell T Brown Photographic Archive).
Streams adjust themselves to maintain an equilibrium between sediment transport and velocity. When the sediment load is too great for the flow, deposition occurs, increasing the gradient below the deposits until the velocity is again sufficient to carry them away. When there is too little sediment, bed erosion decreases the gradient until the load is again in equilibrium with the flow. Any change in velocity, slope, discharge, size and concentration of sediment, channel width and depth, and roughness of the channel will trigger an adjustment of the other variables towards a new equilibrium.
When a stream or stream segment is straightened, as was the South Skunk in the early 1900's, the shortened length results in an increase in gradient and velocity, which in turn increases the sediment carrying capacity. The stream will first downcut into the stream bed, but will eventually begin to cut laterally into the stream banks. Meanders will begin to form, growing both laterally and downstream, as sediments are eroded from the outer bends and deposited as point bars. The channel may also begin to widen, which reduces velocity and can lead to deposition.
Increased flow due to urban stormwater runoff will also increase the sediment carrying capacity of a stream, temporarily, and accelerate the natural erosion process of the bed or banks. This is evident in the previously channelized stretches immediately below Ames, beginning at Lincoln Way.
The Hungry Canyons Alliance of the Golden Hills RC&D has been working to prevent further channel erosion of the highly erodable loess soils in western Iowa. Their website provides a good explanation of stream morpholgy and channel disturbances.
A USDA Demonstration Erosion Control Project addresses the same issues in northwest Mississippi and the Rio Blanco River Restoration Project restores a Colorado stream after a another project diverted 70 percent of the normal flow to New Mexico and Texas.

The 1902 maps at Additional Links show both the original channel and the new "ditch".

Ioway Creek
There's much history along Ioway Creek (known as Squaw Creek until...), including mills, quarries, and coal mining. The 1902 maps at Additional Links show that Squaw Creek once entered the Skunk a mile further south than today. At south Duff the original channel turned south, passing behind B-Bops and crossing Hwy 30 east of George White Chevrolet and the Ames animal shelter. The creek at the end of Billy Sunday Road is probably part of the old channel.

Squaw enters the county at or very near the Squaw Creek Coal Banks. The small branch that passes the "big rock" and empties into Squaw Creek just above the west quarter corner of section 7 (Section 12 in Boone County, south of 170th - rd), that branch forms a valley of coal and of most excellent quality. These banks are in Boone County but a short distance. Here quite a trading point has grown up, and Zenorville is the town. On Skunk and Squaw there are some stone quarries of fair quality. (Page 193 Franklin Township Description, W.G. Allen, 1887)
Worrall's Grove originally covered parts of sections 16, 17 and 18, in Washington Township. This Grove was named after an old and good citizen, named Shadrick Worrall, who was elected, April 4, 1853, as the first Coronor for Story County. This Grove in common with the others shared a loss of timber. Worrall Creek passed through it and entered the flats of Squaw Fork. (Page 388, Groves, W.G. Allen, 1887)
Luther's Grove originally comprised parts of sections 4, 5 and 6, in Washington Township. Luther Creek (now known as Clear Creek - rd) passes through this grove. It once had some good timber in sections 4 and 5. This Grove and the Creek were named for a Mr. Luther, who in very early times lived in the grove, or owned a part of it. (Page 388, Groves, W.G. Allen, 1887)
The Hiestand Mill, a "Tread Mill" with an effort to use water power, was on Squaw Creek, and on the southwest quarter of the northwest quarter of section 33, township 84, range 24 (probably ~ 1/2 mile below Onion Creek and possibly near the present-day Veenker dam - rd). It was built probably about the year 1855. It did only a small business—a "carding mill" and a saw mill. The dam washed out and the water power was a failure. (Page 386, History of Mills, W.G. Allen, 1887)
Thurman's Saw Mill, one-half a mile south of New Philadelphia, was built July, 1856, by D. and H. McCarthy, and moved away, in 1864, and used as Burger's Mill, described elsewhere. The engine was brought from Fairview, in 1855 or 1856. It was placed on Luther Creek (Clear Creek), and did a great deal of sawing while Thurman Bros. run it. It was steam power. D. & H. McCarthy, and Ross and Latham, run it a while before Thurman Bros. took it. (Page 387, History of Mills, W.G. Allen, 1887)
T. McNaughton's saw mill was about eighty rods north of the southeast corner of section 30, township 84, range 24, but did but little business. It was located on Onion Creek, and was run by water power. The impression is that it was taken to Ames by McNaughton and others about the year 1873, and changed into a flouring mill at Ames. (Page 387, History of Mills, W.G. Allen, 1887)
Burger's steam saw mill was on or near the southwest corner of the northwest quarter of the southwest quarter of section 32, township 84, range 24. It was built about 1864, but did not remain very long; but it done some sawing. The engine and machinery of this mill is said to be the same the Thurman Bros. had used. And it was the same used by Thos. McNaughton, after Burger had used it, on Onion Creek. (Page 387, History of Mills, W.G. Allen, 1887)
A good flouring mill was built at Ontario about the year 1870, by I. B. Nelson & Seymore, and was run by steam power. It did excellent work; but Mr. I. B. Nelson, who owned it when it was moved, took it down in June, 1874, and took it to West Side, Iowa, where he put it up again; and at last account it was doing finely. (Page 385, History of Mills, W.G. Allen, 1887)
Corey's Mill, on Squaw Creek, was water power, and was on the northeast quarter of section 14, township 83, range 24 (south of SE 16th Street, on the original channel - rd). It was an early settler and did but little work. (Page 387, History of Mills, W.G. Allen, 1887)
State Forest NurseryThe State Forest Nursery, which lies river right below Hwy 30 and the Hunziker Youth Sports Complex, was a Civilian Conservation Corps Project. From The Legacy of Hope from an Era of Despair: The CCC and Iowa State Parks - The Civilian Conservation Corps was the federal government's first program for America's jobless youth. In the early 1930s, during the depths of the Great Depression, one quarter of the work force was unemployed. About 2.5 million men and women were aimlessly drifting the country. Today, we would call them the "homeless." - Because Iowa had adopted a long-range conservation plan in early 1933, it was among the first states to be approved for CCC camps. - Nationwide, CCC boys were responsible for most of the reforestation accomplished prior to World War II. [31] Reforestation also was high on the agenda of state forester G.B. MacDonald, who served as the state CCC director. MacDonald took full advantage of federal and state appropriations to acquire about 13,000 acres of land for state forests in Iowa. Two CCC camps were assigned to full time forestry work: surveying newly acquired lands, building erosion control structures, grading and surfacing roads, and planting tress. MacDonald also established the state tree nursery at Ames, and a third CCC camp provided the labor to operate it. CCC camps throughout the state planted trees in state parks and collected seeds for propagating more.
Southwest of town near Ken Maril Road the banks have been re-shaped and armored in an attempt to halt further erosion. The project is described in Friend of ISU Funds Skunk River Project. (photos)
265th to Askew Bridge/CambridgeSKUNK FLATS AND SKUNK VALLEY. Union and Grant Townships share more of the Skunk flats than any other township in the county. I am now inclined to believe when the drift-wood is taken from the channel of the river, and when the flat lands along it are well tiled, where it will admit of it, that the Skunk valley will be among the most beautiful and productive lands we have. I believe the improvements will be such in the next twenty years that this opinion will prove correct. Washington township shares liberally of Skunk flats and of the Squaw Creek flats. (Page 266 W.G. Allen, 1887)
Cambridge
Josiah Chandler was the pioneer in this village, building a saw mill on Skunk River in 1853, which was the nucleus of this town. Jairus Chandler was the first resident on the town plat, building his house near the saw mill. Chandler & Grafton erected the steam grist mill soon after, it being finely and expensively furnished and finished.   (Page W.G. Allen, 1887) Jairus Chandler built the water-power saw-mill on the west side of Skunk River and near where the bridge is, but north of it a short distance, in 1853. The steam flouring mill, which was a good one, was built by J. Chandler and Dr. W. H. Grafton about 1855. It stands a short distance southwest of the bridge at Cambridge. (Page 266 W.G. Allen, 1887)

WHERE TO PADDLE?
There are too many resources to list, but here's a good start:
  • Nate Hoogeveen's book, Paddling Iowa, lists "129 Outstanding Journeys by Canoe, Kayak, or SUP" (2021 Edition). If you're new to paddling, be sure to check out Chapters 1 & 2.
  • Online, the Iowa DNR's Where to Paddle page includes an interactive paddling map and a Water Trails Map (pdf, top right). Another page links to Maps, Brochures and Guides.
  • Also online, the DNR's Where to Fish page may be of interest to some.
  • County Conservation Boards often provide printed brochures of their local water trails and share that information online at My County Parks.
  • Don't overlook the PaddleSport Stores. (Crawdaddy Outdoors has an entire page of Iowa River Maps.)
  • Be aware, too, of potential dangers. The DNR's Interactive Map shows the location of dams and other known hazards, and the Iowa Whitewater Coalition maintains a Low Head Dams Reference Page.
WHEN TO PADDLE?
Wind, weather, water temperatures and streamflow are important considerations when planning a paddling trip. Check the wind & weather forecasts before you go, and the streamflow, and then consider whether your skills, your paddle craft and equipment (and those of your group!) are appropriate for the expected conditions.

Every year, warm air temperatures lure people into taking small boats out onto lethally cold water, where a large number of them capsize or fall in - and drown. These folks aren't stupid, or intentionally reckless, and many are good swimmers; they simply have the misfortune of falling into a exceptionally lethal and well-camouflaged trap.
  • Cold Water Boot Camp
Volunteers experience the three effects of Cold Water Immersion (shock, incapacitation and hypothermia) while demonstrating the 1-10-1 rule for cold water survival - and why it is vital to always wear a life jacket. This article was written for whitewater paddlers, but the tips are all useful. "You can avoid overheating by using a simple but powerful technique to offload excess heat. This works whether you're wearing regular clothing or thermal protection like a wetsuit or drysuit." In this article for the Iowa Water Trails Association, John describes concerns associated with paddling large bodies of water.
HOW TO PADDLE?   (Or How Can I Improve My KSAs?)
You can't know what you don't know, so take a class! You'll learn and practice skills that will make paddling safer, easier, and even more enjoyable.
WHAT ABOUT FLOWS AND FLOAT TIMES?
Let's start with float time, since that's pretty easy to estimate. On most Iowa streams you can expect your moving average to be about 2-3 mph, depending on whether you're a "floater" or a "paddler." Low water and headwinds may slow you down, and you'll probably be faster on streams with a high gradient - and during high flows. River mileages can be found in Nate's book (Paddling Iowa), on the DNR's Interactive Map and on the DNR page of  Maps & Brochures.
Real-time streamflow data is readily available online (see River Gauges for links and related information), but suggesting appropriate streamflows is difficult due to the varying interests, experience and abilities of each paddler. First-hand information from familiar and trusted sources (e.g. Paddling Iowa and/or knowledgeable friends) may prove to be the most useful. Lacking that guidance you may want to avoid anything above or below normal, depending on your skill level, that of your paddling partner(s), the air and water temperatures, etc.

MUST I WEAR A LIFE JACKET?
In ~90% of all boating related drownings, the victim was not wearing a Life Jacket (a.k.a. Life Preserver, Personal Flotation Device or PFD). The victims include good swimmers, and we can assume that none of them planned to die and most never planned to enter the water. That's why we call them accidents.
  • Iowa Boating Law requires that you have one USCG approved wearable Type I, II, III or V Life Jacket for each person on board (including SUPs). It must be readily accessible and sized for the intended user. In addition, children under 13 years of age must wear a PFD.
  • Life Jackets Float. Do You? An ACA video that addresses the many challenges of moving waters.

And if you're STILL not convinced, try putting your life jacket on while treading water. IF you're successful, imagine putting it on after an unexpected swim, while trying to keep an eye on your gear and your paddling partner(s).  Maybe your children. And while being swept downstream into a strainer.

ARE INFLATABLE PFDS LEGAL?
Inflatable PFDs are not approved for use by persons under the age of 16, for tow-behind activities (e.g. water skiing) or by operators of personal watercraft. They should not be used for high-impact activities (e.g. whitewater paddling), and unlike inherently buoyant PFDs, they must be worn. It's not enough to have one "on board."
"Everyone who owns or would like to own an inflatable life jacket needs to watch this 9-minute ACA video to learn all about care and maintenance of them." There are some advantages to having the instantaneous buoyancy of a traditional, inherently buoyant PFD, and a concern that users won't know how to inflate their PFD manually should the auto inflation mechanism fail. The delay of inflation may be most critical in cold water because the user is  likely to become completely submerged upon falling in, potentially increasing the cold shock response (see https://en.m.wikipedia.org/wiki/Cold_shock_response). And in below freezing temperatures, the CO2 cartridge may not fully inflate the PFD.

WHICH KAYAK (OR CANOE) SHOULD I BUY?
When people ask this on Facebook they're likely to receive advice from others who know little more than they do. Those well-intentioned paddlers might be in their own first boat and that's all they know. Maybe their needs and interests (including the bodies of water available to them) are different than those of the inquirer. They could be in the wrong boat and don't know it!

So why not ask the experts? Visit the nearest Paddlesport Shop where knowledgeable staff can help you select something that best fits your personal needs, and/or go online to find that CanoeSport Outfitters (Indianola), Rutabaga (Madison) and others have already written on the subject: Things to consider even before you buy your first boat (how to paddle, where to paddle, and who to paddle with). Headwaters Kayak (CA) has dozens of reviews and informational videos on their YouTube page. One takeaway from this video might be that some of the low-cost kayaks will not be of much help in the event of a capsize (meaning that they may not float, so wear your PFD)!
The best advice you'll get might be that you should try before you buy!

River Camping and other potential trespass issues


“Extras” The ACA partnered with Anzovin Studio and the US Coast Guard to create an animated memoir-style video that urges paddlers to take personal responsibility for their safety on the water. The video focuses on the stories of three different paddlers, and tells the harrowing accounts of their near-death experiences on the water.
