Water Shed Clean-Up Plan

October - December 2002

Mike White , crops field specialist


The city of Winterset gets its water from Cedar Lake located north of the city. The watershed supplying the water for this lake comes from an agricultural watershed just less than 11,000 acres in size. The nitrate and atrazine levels of this lake have consistently been above the Maximum Contaminant Level set by the Environmental Protection Agency. The city of Winterset needs to clean up the water supply or face putting in a nitrogen scrubber that has been estimated to cost $750,000. 


Mike White, crops field specialist, has been working with the Madison County Soil Conservation District to help get the watershed project up and running. Information on integrated pest management in relation to the watershed was presented at three private pesticide training meetings. White met with the Cedar Lake Watershed committee on the evening of May 28, 2002 to develop a watershed clean-up plan. On Aug. 22, 2002 White met with the soil conservation district staff and local industry Certified Crop Advisors (CCA's) serving in the watershed. Steps to clean up the lake through integrated crop management practices were discussed. On Sept. 6, 2002 the soil conservation district staff and White partnered with Heartland Cooperative to hold a field day in the watershed. This informational field day centered on proper nutrient and pest management practices.


Farmers in the watershed area have seen a coordinated effort from the Madison County Soil Conservation District, local CCA's, and Iowa State University Extension to inform
them about the problems in the watershed and ways these problems can be solved. This partnering effort has delivered a strong image and strong message. The Cedar Lake Watershed cleanup project has been kicked off to a very good start.
