    What's the problem with Rathbun Lake?
    Located in northwest Appanoose County, Rathbun Lake provides recreational opportunities for 1 million visitors annually and is the primary water source for the Rathbun Regional Water Association (RRWA). Results on water quality monitoring on the largest system in Iowa, and one of the one of the largest rural water systems in the United States, indicate that high levels of nutrients, excess sediment, herbicides and bacteria impact the lake's water supply, recreational and habitat uses.

    Sediment studies conducted by the U.S. Army Corps of Engineers (ACOE) indicate that Rathbun Lake has more sediment than what it was designed to hold. The sediment collecting in Rathbun Lake is occurring at a rate that is faster than anticipated and is coming from sheet and rill erosion. Sheet erosion occurs when rainfall and runoff remove a thin layer of soil from the surface of the land. Rill erosion forms small channels with a concentrated flow of water on sloping fields.

    Nutrients and sediment runoff from areas such as livestock feeding operations, road and railroad intersections, wastewater treatment facilities, septic system concentration areas and recreational facilities are a cause of concern for Rathbun Lake.

    What's being done to help Rathbun Lake?
    The introduction of grassed waterways, terraces, and water and sediment control basins are just a few of the conservation practices working to clean up the water quality in the Rathbun Lake watershed.

    Grassed waterways in the Rathbun Lake Watershed are an effective practice in reducing soil erosion. These natural or constructed channels move surface water across the land without causing soil erosion. The vegetation in the waterway slows the water, protecting the land from rill and gully erosion.

    Another conservation practice implemented in the Rathbun Lake watershed is terraces. Terraces are very efficient in reducing soil erosion and sediment in the 354,160-acre watershed. Terraces are built around a hillside and either slow runoff and guide it to the bottom of the hill or collect runoff and store it until the runoff can be absorbed by the ground. Terraces must be properly designed and maintained to combat erosion.

    Water and sediment control basins are another conservation practice helping to improve water quality in the Rathbun Lake watershed. These structures are built across gullies and are effective for preventing gully erosion, trapping sediment and reducing downstream water flow.

    What can I do to help?
    For landowners in the Rathbun Lake watershed, there are many unique opportunities to help improve the lake. Velvet Buckingham, project coordinator, can work with you to evaluate your land and identify practices that can help both the lake and your property. Buckingham can also help find financial assistance to install those practices. Landowners participating in the watershed project can get up to 75 percent cost share in targeted areas.

    The Rathbun Lake Watershed Alliance (RLWA) is working to promote safe conservation practices by hanging up signs to direct interest in the Rathbun Lake watershed and also conducts field days for farmers and acreage owners to show how different conservation practices work.

    The RLWA has educated school districts around Appanoose County by talking to high school Future Farmers of America (FFA) groups and hopes to make the transition to educating elementary and middle school students in the near future.

    Since the 1990s, the Iowa DNR, Iowa State University and U.S. Army Corps of Engineers have conducted water quality monitoring for pesticides, nutrients, bacteria and sediment in Rathbun Lake and the lake's tributaries. The monitoring program consists of monthly and event sample collection and analysis from 15 tributary sites in the watershed, four sites in the lake and one site at the lake outlet in the Chariton River.

    What is the future of Rathbun Lake?
    Once most of the projects are completed, the public will be able to see a drastic difference in water quality at Rathbun Lake.With the completion of
    Honey Creek Resort State Park in late summer 2008, visitors will enjoy a one-of-a-kind experience at Rathbun Lake.

    Velvet Buckingham enjoys the unexpected events of each business day.

    Meet the project coordinator
    Velvet Buckingham grew up in Plano, Iowa and attended Northwest Missouri State University in Maryville, Missouri for two years before transferring to Iowa State University in Ames, Iowa. She earned a major in agricultural business in May 2001 and now works for the Rathbun Regional Water Association.

    "I really enjoy the unexpected events of each day in the business and believe that everyday is a new challenge," said Buckingham. "I like working and seeing quality results."
