Rescheduled Charles City Challenge: WhiteWater Weekend was finally held June 28-30
|
Our thoughts are with all of you, as you navigate your scheduled WT activities and events through the mood swings of Mother Nature. Kind of difficult to find mussels when the river is at flood stage, isn't it? Our challenge is to keep folks informed without overloading their email in-boxes, so we're relying on a combination of occasional updates and lots of encouragement to check the event website or call ahead before traveling any great distance. With your assistance, we'll do our best to encourage participation in your event, whether it's on schedule or rescheduled. Let's hope that July is the month that Iowa's rivers return to normal levels, the birds eat all the gnats, and we can really enjoy our growing network of WTs. |

What Water Trail Means: Steamboats Arrive on the Mississippi "Water Trail" |

"The first steamboat came down the Mississippi in 1811--in fact, it was swamped and almost sank in the backwash of the Great Shakes (editor--a series of earthquakes near New Madrid, one of which caused surface waves making the river appear to run upstream). By the end of that decade, around a dozen steamboats were on the river system. In the 1830s, the steamboat population was estimated to be around five hundred. By the time of the Civil War, it was four thousand. "There was a simple explanation for the ascendancy of the steamboats: they could move upriver almost as easily as they did down. This gave them a decisive advantage over every other form of river transport. They rendered the old, ornate, impractical keelboats obsolete--no need for bushwhacking or cordelling when the steamboats could churn their way up against the strongest current. Keelboats disappeared from the river by the 1840s. By the 1850s, even the flatboat population was in decline. The only serious competition the steamboats had left was the great rafts and barges--they survived because the steamboats didn't have their bulk carrying capacity. "The rise of the steamboats also wrecked the old river etiquette. The river had never been policed, but there had always been a logic to its traffic flow, one dictated by practical necessity: the downriver traffic ran in the channels, while the upriver traffic stuck to the shallows. The steamboats put an end to all that. They cut in and out of the channels no matter which direction they were traveling. Their pilots were notoriously indifferent to the chaos they could leave in their wake. The steamboats routinely swamped the smaller boats as they passed; often they ran right over them and blasted them to splinters. And if the boat people were injured or drowned, if their boats were destroyed and all their possessions were sunk, there was no recourse. It wasn't uncommon for the boat people, when they saw a steamboat approaching--particularly one with a reputation as a channel hog--to bring out their rifles and take shots at the pilothouse."

Jul 6-13 Project AWARE, Des Moines River Between Algona and Lehigh |
Media Contact: Lynette Seigley at 319-335-1598 or Lynette.Seigley@dnr.iowa.gov
Volunteers will have an opportunity to spend July 6 to 13 working as aquatic garbage collectors - cleaning up, learning about, and exploring more than 90 miles of the Des Moines River between Algona and Lehigh in north-central Iowa.
Project AWARE (A Watershed Awareness River Expedition) is the DNR's annual volunteer river cleanup event. In addition to removing trash from the river, volunteers will learn about watersheds, water quality, recycling and other natural resource topics.
"We're excited to embark on our eleventh Project AWARE, as we engage Iowans in becoming caretakers of Iowa's water resources and demonstrate that the commitment of volunteers can make a difference," said Lynette Seigley, the Project AWARE coordinator. "Project AWARE also provides an opportunity for Iowans to improve their mental and physical health through outdoor recreation - a great part of the DNR's Healthy and Happy Outdoors initiative."
Registration is required for those who wish to volunteer for the river cleanup. To avoid a late registration fee, volunteers must have their registration forms postmarked by Friday, June 21. Tent camping is free for volunteers and a limited number of canoes are available for those who need them.
Volunteers can help with the river cleanup by paddling the river or by assisting with land-based recycling initiatives, but there are opportunities for others to experience Project AWARE as well. Educational programs are held each evening and are open to the public. Registration is not required to attend evening programs.
Additional information about evening programs and Project AWARE can be found at: www.iowaprojectaware.com. More information on Healthy & Happy Outdoors is available at www.iowadnr.gov/h2o.

Campaign Aims to Clean Up Behavior on Upper Iowa River |
A series of special meetings last fall with landowners along the Upper Iowa River revealed some disturbing behavior by individuals who frequent Iowa's signature inland stream. Trespassing. Alcohol abuse. Underage drinking. Public nudity. Public urination. Littering. Vulgar language. And the list goes on.
Floating the Upper Iowa River was once included on the National Geographic's America's 100 Best Adventures list, but to those living nearest the river, much of its attraction has been diminished by those who use it. "We heard stories of people coming home to find an intoxicated person in their kitchen making a sandwich, about encounters with intoxicated people looking for a ride home, or vomiting or urinating on their property," said Nate Hoogeveen, river programs coordinator for the Iowa DNR.
Hoogeveen met earlier with other players in the area to discuss the possibility of designating the Upper Iowa River as a state water trail. At these listening sessions, a number of concerns were discussed about the existing behavior by some of the river users. "We want people to have fun on the river but not at the expense of others. We need to take these reports seriously," said Hoogeveen.
The local meetings lead to an effort to remind river users that their behavior affects other people, including neighboring landowners. Keep it Clean, Keep it Fun for Everyone is a new campaign to improve the behavior on Iowa rivers.
"These problems didn't develop overnight and won't go away overnight," said DNR Director Chuck Gipp. "We need support locally to report problems and hold individuals accountable for their behavior. The Upper Iowa River is one of our most unique treasures and we need to treat it with respect and appreciation that it deserves."
The DNR is working to target law enforcement presence on the river as a way to reduce some of the illegal activity. The liveries will also include materials in their rentals to help paddlers report illegal activities they witness.
Littering is a significant problem on the Upper Iowa River, especially at access points, and the DNR will be distributing green mesh bags that people can take with them and pick up litter as they go. "We need all of our users to respect the resource and take out what they bring in," he said. "Respect the private property rights of landowners living along the river, including the sandbars and riverbanks. Nearly all of Iowa's river bottoms are privately owned."
Another thing users can do to make the Upper Iowa more inviting is to clean up the language, he said. "Rude behavior, foul language and loud music were noted by landowners on several occasions as something that needed attention," Hoogeveen said.
Businesses and public agencies who want to support this campaign can request posters and decals from Iowa DNR by calling Todd Robertson at (515) 979-9538 or sending a request to Todd.Robertson@dnr.iowa.gov.

IRR Master River Steward Classes in Cedar River Watershed Jul 24--Aug 28; Register Now! | 
Recruitment Deadline: July 19, 2013 (please inquire about availability after this date.)
Contact: Jenn Dreier, Administrative Coordinator, jdreier@iowariver.org; 515-724-4093.
Pioneered by IRR in 2012, this multi-class course offers a focus on riverine systems, including sessions on understanding watershed geology and river form, restoring aquatic habitat, improving water quality, and understanding policies related to floodplains, river protection and restoration. A 2013 Des Moines/Raccoon River Watershed IRR Master River Steward Program, with 23 students, was held earlier this year.
The Master River Steward Program builds on a network of river experts from various partner agencies and organizations, helping adult learners collaborate to protect and improve Iowa's rivers. Participants in the 2012 course raved about the program's content, presenters, leadership, resources, and the opportunity to meet and work with others who share their interests and concerns.
Participants pay a fee of $50, receive program materials, are expected to attend each session, and will have "homework" assignments. Read more at: http://iowarivers.org/education/river-stewards/

Iowa DNR Reminds Us That High River & Streams Warrant Caution |
Hot, humid weather has Iowans seeking ways to cool off. Although the drought is officially over, water-loving Iowans should do their homework before deciding to boat, paddle or tube a river.
"Throughout June, we received several reports of rescue situations along rivers," said Nate Hoogeveen, river programs coordinator for the Iowa Department of Natural Resources. "While some rivers have dropped to easier levels, last weekend's rains put some of the most popular rivers well above safe levels for paddlers and innertubers." The Upper Iowa River, for example, rose to 14,000 cubic feet per second on Sunday, whereas its "normal" or median flow is 400 cubic feet per second at this time of year. "Rivers fluctuate a lot, and some that are too high now might be in better shape within a week or two," said Hoogeveen. "Or, they might be flooding."
It is important river users know it's their job to make good decisions about taking the trip in the first place. At high water, it can quickly become a matter of life and death. Hoogeveen offered the following tips:
- Wear your life jacket: Life jackets, when properly fastened and cinched, save lives. Life jackets are mandatory for any child under 13 in any vessel underway in the state of Iowa.
- Recognize and avoid hazards: Most high water incidents involve an obstruction - downed trees and branches create a "strainer" effect that can trap boats and people under water, sometimes leading to drowning. A bridge pier or boulder can get a boat pinned on its upstream side. Low-head dams can re-circulate, trap and drown victims. These hazards are most difficult to avoid at mid to high range flows.
- Learn more before you go: If you are renting, call the outfitter, describe your level of experience and ask whether it sounds like a safe level for you. Otherwise, review river gauge data nearest the segment you plan to visit at http://waterdata.usgs.gov/ia/nwis/current/?type=flow. On the "Discharge" graph, find the "median daily flow" triangles. If the current water level reading is more than 50 percent higher than the median in late June to early July, use extra caution.
- When you arrive: If timber and debris are floating down the river or the river is out of its banks or nearly so, don't launch.
- Consider your experience: Novice paddlers and tubers generally have less control as rivers get swifter, and should factor in more caution.
- Other factors: You can improve your odds by not consuming alcohol, considering weather factors, bringing appropriate rain gear and being vigilant about what's around the next bend.

Photo of Des Moines River Valley
by Leland M. Searles
|
Leland Searles shared this photo of the Des Moines River valley, taken from the east end of the High-Trestle Bridge, west of Madrid, Iowa.
Leland explains, "Compared to the stretch of the river from its namesake city downstream, the bluffs of the Des Moines here on either side are fairly close. A severe flood might cover almost the entire valley. At this point the river flows through the landform area known as the Des Moines Lobe of the Wisconsin glacial surface. About 12,000 to 15,000 years ago, as the last large glacier sheet was melting and retreating, the amount of water flowing down the newly formed river channels was tremendous. "Southeast of the capital city these melt-waters used existing river channels and carried huge amounts of rock and dirt from the bluffs. But north of Des Moines any older rivers were covered or erased by the advancing glaciers. When they melted, the water shaped new channels in the glacial debris. North of Des Moines, including here at the High-Trestle Bridge, the river valley is relatively narrow. There still fertile farmland on the river terrace, evident in the photo. It appears that the landowner has chosen to leave standing corn for wildlife. Above the field is the bluff, with stands of oak-hickory woods, mixed with other species that favor the wetter bluff bases. Careful excavations in the field would reveal layers of gravel, sand, and silt and clues to the river's history over the last dozen millennia: floods, droughts, meanders, oxbows, and other features, along with their ecosystems."

What Is It? Quiz ANSWER |
 | Photo of Timber Crib Remnants on Wapsipinicon River by Gregg Stark |
Remnants of a wood crib dam were visible during low water on the Wapsipinicon River, in an area with no other existing structures or even a road. While little is known about the site, it is believed to be one of the many small mills built in Iowa in the 1800's which was reached by a dirt road, probably provided a river crossing point, and offered grain milling or sawmill services to area residents. As with many such enterprises, it probably succumbed to market forces or river flooding, and the old road did not provide a significant transportation link.
Timber crib dams were erected of timbers in the same manner as a log house, and the interior was then filled with rocks. Early entrepreneurs could build them relatively quickly from locally available materials utilizing basic skills, but the dams were limited in height and longevity.
Such discoveries should not be disturbed, but rather enjoyed for a glimpse into history, and possibly reported to the State Office of Archaeologist: http://www.uiowa.edu/~osa/about/contact.htm
