Maintaining the integrity of our watersheds provides economic benefits through ecosystem services. Degradation of stream banks, aquatic species and the natural course of water can cause negative economic impacts locally and far from the altered site.
Protecting Healthy Watersheds:
- Lowers drinking water treatment costs
- Avoids expensive restoration activities
- Sustains revenue generating recreational and tourism opportunities
- Minimizes vulnerability and damage from natural disasters
- Provides critical natural system services at a fraction of the cost for engineered services
- Increases property value
- Supports millions of jobs nationwide
- Ensures we leave a foundation for a vibrant economy for generations to come
We cannot afford not to protect our watersheds.

Forty years ago, in the midst of a national concern about untreated sewage, industrial and toxic discharges, destruction of wetlands, and contaminated runoff, the principal law to protect the nation’s waters was passed. The Clean Water Act (CWA) set a national goal “to restore and maintain the chemical, physical, and biological integrity of the Nation’s waters,” with interim goals that all waters be fishable and swimmable.
The Act embodied a new federal-state partnership, where federal guidelines, objectives and limits were to be set under the authority of the U.S. Environmental Protection Agency, while states, territories and authorized tribes would largely administer and enforce the CWA programs, with federal technical and financial assistance. In Iowa, the Iowa Department of Natural Resources is delegated to administer the CWA.

Des Moines Water Work’s primary water sources are the Raccoon and Des Moines Rivers. Land use in the Raccoon and Des Moines River Watersheds is overwhelmingly agricultural. About 1.7 million of the 2.3 million acres in the Raccoon watershed is cultivated for corn and soybeans. Land covered by perennial vegetation is nearly non-existent outside urban areas. Much of the corn-soybean system requires constructed drainage (agricultural tile drainage) to maximize yields. Manure and commercial fertilizers applied to crop land are transported during rainfall events as either run-off or discharged to a river through a tile drainage system. All of these factors have resulted in various consequences for water quality and challenges for drinking water utilities.
Today, the Iowa Environmental Protection Commission (EPC) will meet to discuss whether or not to continue to ban manure application to soybean crops. Manure is a source of nutrients used in combination with or in place of commercial fertilizer. Nutrients in water are necessary for healthy watersheds; however, in high concentrations they can adversely affect aquatic life and human health. For a drinking water utility, increasing nutrient loads can cause difficult and costly challenges at the source, in the treatment process, and at the tap. Monitoring trends in the Des Moines and Raccoon River since 1974 show the ever-increasing trend of nitrate-nitrogen (a nutrient) loading and concentrations. Without a comprehensive, measurable state nutrient standard and strategy these conditions will be perpetuated.
All waters in Iowa are “public waters and public wealth” of its citizens and is for the beneficial use of all citizens. It is also the policy of the State of Iowa – delegated to the Iowa Environmental Protection Commission – to protect existing water uses and to protect and maintain the physical, biological and chemical integrity of all waters of the state. Making a decision on whether manure should be applied to soybeans is again representative of the piecemeal approach to nutrient management that will not effectively decrease non-point source nutrient contributions to Iowa’s surface and ground water resources.
Des Moines Water Works provided comments to EPC commissioners strongly urging them to take this opportunity to support development of comprehensive nutrient management strategies and standards. Standards that protect Iowa’s water resources, promote economic development, and enhance the quality of life necessary to attract workers and jobs to the state. And most importantly, establish the target so many producers and the public have requested.
It is not Des Moines Water Works’ intent to tell people how to farm or what they can and cannot do on their land. But it is our intent, to rigorously advocate for establishing a comprehensive nutrient strategy, setting numeric nutrient standards, and the aggressive reduction of non-point source nutrient contributions to Iowa’s surface and ground water resources.
Des Moines Water Works and the drinking water industry ensures that the investment the public has made in them results in all Iowans having access to safe drinking water. We believe every Iowan who drinks a glass of water should recognize the importance of our water resources to sustaining life and the critical connection between our water resources and food production, an existence and connection that should occur without degradation of our water resources.
Producers are able to make all the decisions on his or her land, but those decisions are having dramatic consequences that impact others. Integrated solutions on a watershed scale and involvement of all stakeholders in the planning and implementation process is critical to generating change. Whether you live in an urban, rural or something in-between, we are all part of the watershed and whatever we do in our daily lives impacts water quality in the watershed.Labels: Des Moines Water Works, Des Moines waterworks, DMWW, Raccoon River, Source Water, water quality, Watershed Posted in Environment, Source Water, Water Quality July 30, 2012
Des Moines Water Works through the Central Iowa Regional Drinking Water Commission Assisting Dallas County Board of Supervisors in Formation of a Middle-South Raccoon River Watershed Alliance
The State of Iowa has authorized local governments to address flooding and management of water and soil resources in watersheds across the state through the formation of local alliances. An alliance is formed through a 28E agreement (contractual agreement between governmental organizations) with representatives appointed by city, county and soil and watershed conservation districts (SWCD) within the watershed. An advisory body with landowners and other groups will also be part of the process. The watershed alliance has no taxing authority and no impact on the authority of a city, county, or SWCD to conduct its business. Instead, the alliance will educate, coordinate and leverage resources for the betterment of the watershed.
The Middle-South Raccoon River Watershed Alliance is working within the following vision and mission statements:
Vision: A regional alliance with resources to lead, and support improvements in soil protection, flood management and water quality.
Mission: To facilitate regional collaboration that will identify strategies and goals to educate the public, reduce the risk of flood events, and leverage resources for improved soil and water quality protection.
As outlined by legislators in Iowa Code the alliance can:
- Educate residents
- Identify sources of funding to institutionalize the Watershed Management Alliance
- Assess flood risks
- Assess options for cutting flood risk
- Monitor state & federal flood risk planning activities
- Assess water quality
- Leverage funding of multiple partners
- Allocate state and federal moneys available for water quality and flood risk reduction programs and implement best management practices
- Implement the Raccoon River Master Plan
- Enter into contracts and agreements

The Middle-South Raccoon River Watershed Management Alliance has just recently been selected to partner with the Iowa Flood Center (IFC) on a multi-year project to monitor, plan, and implement watershed projects aimed at improving soil and water resources and the adverse impacts of flooding. Phase I will focus on the Middle Raccoon River watershed. The IFC formally announced the partnership June 22, 2012, in Redfield, IA.
The landscape of the Middle-South Raccoon River Watershed is located in the best of rural Iowa, where community is tied to the tradition of farming and outdoor recreation. The benefits gained from the partnerships in the Middle-South Raccoon River watershed is a place where agriculture, communities, recreation, and Iowans thrive and prosper.Labels: Des Moines Water Works, Des Moines waterworks, DMWW, Raccoon River, Source Water, water quality, Watershed, Watershed alliance Posted in Environment, Flooding, Source Water, Water Quality August 23, 2011
We all live in a watershed. Do you know what watershed you live? Learn how nature and our indivdual actions can directly impact the quality of water in our watershed in this video. Des Moines Water Works continues to protect watersheds and give you Water You Can Trust for Life.
A watershed is an area of land that water flows over or through on its way to a stream, lake or river. Within each different watershed, the land “sheds” or gets rid of water into a common body of water. A watershed also includes the people, air, plants and animals that call that land “home.” Residents of the Des Moines metro area live in both the Des Moines River and Raccoon River watersheds, which begin about 200 miles north and west of the city. These rivers serve as the primary sources for our drinking water.
Precipitation, run off, agriculture tile drainage or any other water from farmland and urban areas between the Minnesota border area and Des Moines will eventually end up in one of these two rivers. When it rains or snows, water carries pollutants such as dirt, oil and fertilizers to our rivers and lakes. Controlling pollution is key to improving the quality of our water supply.
There are two types of watershed pollution: point-source and nonpoint-source. Point-source pollution is an easily identifiable source, like wastewater treatment plant or industrial discharge. Nonpoint sources of pollution are difficult to identify, isolate and control. Examples of non-point source pollution include run off from parking lots, run off and tile drainage discharge from agricultural fields, feedlots, lawns and failing septic systems.
Everyone, from farmers to urban residents, can contribute to improving watershed health. Even the smallest contribution can make a significant impact in preserving and protecting our water.
You can keep our watersheds clean and safe by following these healthy, environmental tips. These can be practiced at home, work and community, to enjoy and maintain a healthy living environment!
- Don’t dump! Do not dump hazardous household chemicals, such as fertilizers, oil-based paint or antifreeze down a drain in your home or a storm sewer in your neighborhood. Take these chemicals to the Metro Waste Authority’s Regional Collection Center in Bondurant for disposal. Call (515) 967-5512 for more information. Yearly neighborhood SCRUB days also offer limited hazardous chemical disposal.
- Recycle! Recycle your newspapers, magazines, milk jugs, water bottles, juice bottles, metal cans, clear glass, and anything else possible to reduce the quantity of garbage you send to the landfill.
- Love nature! Plant grass, trees and shrubs, especially native species to prevent soil from eroding.
- Drive smart! Keep your vehicles in good condition to prevent oil and antifreeze leaks from entering storm sewers.
- Don’t litter! Pick up after yourself and your pets. You can also volunteer to help clean up area parks.
The Iowa Department of Natural Resources has contracted with the Missouri & Mississippi (M&M) Divide RC&D and Agren, both located in Carroll, Iowa, to develop a comprehensive watershed plan for the Raccoon River. Agren, Inc. was founded by brothers Tom and Stan Buman in 1996 as a private consulting firm dedicated to helping agriculture find profitable solutions to environmental challenges. The master plan will guide management efforts with a focus on improving water quality in the Raccoon River watershed.
Agren facilitated “expert panels” to evaluate both agricultural and urban stormwater best management practices (BMP). Following the expert panel events, the potential water quality impacts of recommended practices were estimated by Iowa State University scientists. More than 80% of the land use in the watershed is dedicated to row crop agriculture, so initially the implementation plan will concentrate on agricultural BMPs. Consideration is also being given to various incentives and funding sources for implementation of the recommended practices.
This month, another panel focused on what a watershed management organization should look like to ensure the master plan is implemented when completed. Des Moines Water Works (DMWW) participated on the panel. Discussion consisted of what the barriers are to effective watershed management, what type of watershed authority could overcome the barriers, and evaluation of scenarios for watershed management. Throughout the discussion it was apparent that DMWW will continue to be a key partner in managing the Raccoon River Watershed.
Recommendations best suited to protect the source of drinking water for approximately 500,000 people in central Iowa and restore and maintain an environmentally and economically sustainable landscape. These recommendations will be compiled into a comprehensive Raccoon River Watershed Master Plan. Public comments on the plan will be solicited this spring, with the final plan development completed by June 2011.Labels: Des Moines Water Works, Des Moines waterworks, DMWW, Raccoon River, water quality, Watershed Posted in Environment, Public Policy, Value of Water, Water Quality February 2, 2011
A watershed is an area of land that drains to a common point. The 3,600 square miles of the Raccoon River Watershed drains to the confluence of the Raccoon and Des Moines Rivers in downtown Des Moines. The Raccoon River rises in Buena Vista County and travels approximately 200 miles to its mouth. The mainstem of the Raccoon is known as the North Raccoon River in its upper stretches and has two main tributaries: the Middle and South Raccoon Rivers. The Middle Raccoon River begins in northwest Carroll County and flows 76 miles to join the South Raccoon near Redfield, IA. The South Raccoon River starts near the Guthrie-Audubon County line and flows 50 miles until its confluence with the Middle Raccoon. The combined flows of the Middle and South Raccoon join the North Raccoon near Van Meter, a few miles downstream from Redfield.
The watershed mainly lies in the Des Moines Lobe, a remnant of the last Wisconsinan ice age. The Middle Raccoon traces the furthest edge of glacial advance, also known as the terminal moraine. This landscape was shaped only 12,000 years ago, much more recently than the rest of Iowa. Soils are among the most fertile on earth, and 80% of the area is cultivated for corn and soybeans.
In 1844, Captain James Allen and his Dragoon explorers were first Europeans to explore the watershed. His journals describe numerous lakes scattered throughout wet and dry prairie, and bears and elk being killed for food during the expedition. A grizzly bear was spotted on the ridge that separates Beaver Creek from the North Raccoon.
No one alive today has seen the Raccoon River in its natural state. Early settlers transformed the landscape into agricultural land through removal of native plants and systematic drainage, a process that continues to this day. The prairies and wetlands of the region were largely gone by 1900. This landscape modification dramatically altered the character, appearance, and water quality of the river to the extent that the river would be largely unrecognizable to people who saw it prior to 1860.
Watershed, catchment, and drainage basin are all the same thing: an area of land that drains to a common point. Small watersheds drain into larger watersheds in a hierarchical pattern. For example, the Mississippi River Watershed is comprised of hundreds of other smaller sub-watersheds.
The City of Des Moines is located at the bottom of two large catchments: the Raccoon and the Upper Des Moines River watersheds. These are two of the 42 largest sub-watersheds in the Mississippi River basin. Water draining from more than 5 million acres, from as far away as Jackson, MN, flows through the city. Des Moines Water Works treats water from both rivers to provide Des Moines Area residents with drinking water.
Knowledge of Iowa’s geological history and current land uses are necessary to understand each river and its water quality. Both the Raccoon and Des Moines Rivers flow through and drain the Des Moines Lobe Landform. It was here that a glacier covered the landscape only 12,000 years ago. The weather warmed and the disintegrating ice sheet formed the prairie pothole region that was once home to uncounted millions of waterfowl. After the glacier melted, the landscape was colonized by tallgrass prairie and wetland plants that helped form the region’s tremendously rich soil. The rivers ran clear and cold as rain water was naturally filtered through the perennial vegetation.
The early European settlers found the region nearly uninhabitable due to the swampy landscape and swarms of mosquitoes. A few decades after arrival, they realized that the soils formed under such conditions were ideal for the cultivation of corn. But first, large scale drainage was necessary. Networks of porous drainage pipes (now known as tile) were buried to lower the water table and dry out the soil. These were connected to constructed drainage ditches, essentially forming hundreds of new streams where none previously existed. This enormous project was mostly complete by 1920, although farmers continue to connect into and improve the system in the present day.
Constructed drainage and replacement of perennial vegetation with annual crops turned Iowa into the world’s richest agricultural region. But altering the natural hydrological system also had an impact on water quality in Iowa’s streams, this is will be discussed in the next piece in this series.
