Ann Lake Watershed Targeted Fertilizer Application

The Wright County Soil and Water Conservation District (SWCD) will implement a targeted fertilizer application program in the Ann Lake watershed, allowing producers to measure soil fertility and apply needed fertilizer more accurately, preventing over-application and consequent runoff of nutrients, especially phosphorus, into surface waters. Phosphorus reduction will help meet the goals of the County's Water Management Plan and the TMDL implementation plan for Ann Lake. The project also is expected to build trust between the agricultural community and SWCD staff, leading to more effective implementation of future water-quality projects. One of the objectives of the SWCD's 2011 Water Management Plan amendment is to influence agricultural operators to use practices that reduce negative environmental impact on natural resources. In addition, the 2012 TMDL implementation plan reports that Ann Lake is impaired because of excess nutrients. To meet state water quality standards for Ann Lake, phosphorus loading must be reduced by 1,591 pounds per year, or 81%. Both of these objectives are directly accomplished by this program. Local benefits include cost-savings for the farmer and improved water quality locally and downstream.
