Yahara Lakes 101 with Dane County Executive Joe Parisi

Impacts of Conservation and Legacy Sediment on Water Quality within the Dorn Creek Watershed

Conservation efforts have been occurring for decades throughout the County and the Yahara to help reduce the amount of agricultural nonpoint pollution entering nearby streams, rivers, and lakes. Although these efforts have helped, the overall goal of meeting the state’s water quality criterion for many of these waterbodies has not occurred. Dane County in partnership with the Wisconsin Department of Natural Resources have been investigating instream legacy sediments as a potential signficant source of nonpoint pollution and water quality impairment within the Dorn Creek watershed located on the northern side of Lake Mendota. Although extensive conservation systems have been implemented to improve water quality within the Dorn Creek watershed legacy sediments appear to be working against these improvements.

Kyle Minks and John Reimer of the Dane County Land & Water Resources Department will give the talk.
