    What's the problem with Casey Lake?
    Casey Lake, located in Hickory Hills park in Tama County, landed on Iowa's impaired water list because its water fell below standards set by the state for supporting aquatic life. Much of the problem at Casey Lake is excessive sediment and high nutrient levels. Poor water quality can result from many types of sediment erosion including, sheet erosion, rill erosion, gully erosion, streambank erosion and shoreline erosion.

    Sheet erosion occurs when rainfall and runoff remove a thin layer of soil from the surface of the land.

    Rill erosion forms small water channels on sloping fields.

    Gully erosion happens after heavy rains or snowmelts and the concentrated runoff creates channels or ditches in the soil.

    Streambank erosion occurs when water in streams removes soil from the streambank. Some streambank erosion happens naturally, but livestock using the streams can trample the banks, which can result in a higher rate of erosion.

    Shoreline erosion happens when water in the lake removes soil from the shoreline.

    Nutrients are another factor threatening water quality at Casey Lake. High nutrient levels can lead to poor water quality and cloud the water. This can create low oxygen and high ammonia levels, which are harmful to fish and other aquatic life and lead to potentially toxic algae blooms, as well as a variety of other problems.

    What's being done to help Casey Lake?
    The Hickory Hills Water Quality Project has a number of conservation practices for farms and country living. Landowners in the Hickory Hills area can improve the lake by partnering with the Hickory Hills Water Quality Project.

    Larry Jones, watershed project coordinator, can work with you to evaluate your property and identify practices that can help both the lake and your property. Jones can also help find financial assistance to install those practices. Landowners participating in the watershed project can generally get improved financial assistance opportunities.

    Since the improvement program began in 2005, the Hickory Hills Water Quality Project has installed two water and sediment control basins in the watershed. Water and sediment control basins are an effective conservation practice used against sediment as they can reduce sediment by nearly half. These structures are built across gullies and are effective in trapping sediment. These structures must be installed and maintained properly to see a reduction in sediment.

    The Hickory Hills Water Quality Project has also installed two wetlands in the watershed with the goal of trapping sediment, preventing soil particles and attached pollutants from reaching the lake. This removal can be important because dissolved nutrients often have the greatest impact on water quality during the summer. Wetlands can also reduce peak water flow, which can help to prevent streambank erosion and flooding.

    What can I do to help?
    Landowners can consider installing conservation practices to control the amount of sediment, nutrients and other pollutants reaching Casey Lake.

    Financial assistance is available, and the benefits extend beyond cleaner water - often conservation practices can produce financial benefits, create recreational opportunities and provide habitat for wildlife.

    The Hickory Hills Water Quality Project is also taking an educational approach to improving the watershed. The project is working together with students at Hawkeye Community College in Waterloo by encouraging students to take part in workshops and events held throughout the year.

    What is the future of Casey Lake?
    In 2008 the Hickory Hills Water Quality Project slated to wrap up and with continued involvement from landowners and citizens in Tama County, the future of the watershed is only going to get better.

    Larry Jones enjoys getting to know the landowners in the watershed.

    Meet the project coordinator
    Larry Jones grew up in Poweshiek County before attending Iowa State University and majoring in agricultural business. Jones graduated in 1987 and began as project coordinator of the Hickory Hills Water Quality Project in 2005.

    "I really enjoy getting to know the landowners and being able to work outside and enjoy nature," said Jones.

    For other ways you can get involved with the Hickory Hills Water Quality Project, contact Larry Jones, watershed coordinator, at (641) 484-2701 or larry.e.jones@ia.usda.gov
