    What's the problem with Lake Macbride?
    Lake Macbride is located in the northern part of Johnson County and is situated in the North Corridor, which is one of the fastest growing areas in the county. The lake has been home to more than 450,000 visitors annually for the past six years. But according to Iowa's impaired waters list, siltation and nutrients from agricultural and urban nonpoint source pollution are impacting the water quality at Lake Macbride.

    Nonpoint source pollution happens when rainfall, snowmelt or irrigation water runs over land or through the ground and picks up pollutants and deposits them into streams, lakes or groundwater. Those pollutants include excess soil, bacteria and nutrients.

    What's being done to help Lake Macbride?
    Under the leadership of the Watershed Advisory Committee, consisting of 15 members, the Lake Macbride Watershed Project is improving the quality of water before it reaches Lake Macbride. A few of the major conservation practices the committee has started are buffer strips, grade stabilization structures, water and sediment control basins, grassed waterways and wetlands.

    Vegetative conservation buffers slow sediment and filter runoff water before it reaches a stream. In addition, buffers reduce erosion from wind, help stabilize streambanks and provide habitat for wildlife.

    Gully erosion is one of the ways sediment is delivered to Lake Macbride, but countering this is the use of grade stabilization structures. These structures are used to reduce water flow while protecting soil from gully erosion.

    Grassed waterways in the Lake Macbride 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.

    Lake Macbride is also creating wetlands, which trap sediment, preventing soil particles and attached pollutants from reaching the lake. Wetlands can also reduce peak water flows, which can help to prevent streambank erosion and flooding.

    There are many educational opportunities citizens can get involved in with help from the Watershed Advisory Committee. They provide educational workshops and technical assistance to homeowners, farmers and Solon School District students. High school students labeled storm drains in the city because many people do not realize that storm drains lead to streams and not to the sewer plant to be treated. Students also planted rain gardens on the high school grounds to absorb water, reduce water, protect water quality and prevent flooding. Rain gardens are a shallow depression in the ground that are strategically located and planted with native wetland or wet prairie wildflowers and grasses.

    What can I do to help?
    Landowners, as well as urban homeowners, in the Lake Macbride watershed can improve the lake by partnering with the Lake Macbride Watershed Project.

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

    Meet the project coordinator
    Amy Bouska grew up in Illinois and spent much of her summer with her siblings and friends exploring the wooded ravines behind the house. Throughout her childhood years, her interest in the environment continued to grow as she participated in Girl Scouts and eagerly awaited visits to her grandparents' farm. From 1996 through 2001, Bouska focused on urban conservation and in 2001 helped the Johnson District complete the planning and grant writing for the Lake Macbride Project.

    "Being a coordinator is very rewarding; said Bouska. I really enjoy getting to know the landowners. I especially love spending time outside working to develop long-range plans for the land...exploring the fields just like I did as a child in the woods bordering my house. It's quite rewarding to see all the projects that have been installed in the watershed as a result of a targeted effort.
