The City of Apple Valley will conduct a subwatershed assessment on the sections of Apple Valley draining to Keller Lake to target potential projects. The goal is to identify potential cost effective retrofit projects and operations improvements capable of fulfilling needed phosphorus reductions ahead of a number of planned infrastructure projects tentatively scheduled for 2018-2022.
The Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
This project seeks to inventory twenty registered feedlots identified as having an Unpermitted Liquid Manure Storage Area. Specifically, this inventory would include offering cost-share for soils investigations. These feedlots are located in three townships that have also been identified as having groundwater that is vulnerable to nutrient pollution, necessitating a need for nitrate testing per MN Department of Agriculture. These townships also house the vast majority of remaining unpermitted Liquid Manure Storage Areas in the County.
