Crow Wing River Watershed TMDL

This TMDL study includes seven lakes and twelve streams located in the Crow Wing River Watershed (HUC 07010106), a tributary to the Mississippi River in central Minnesota, that are on the 2014 USEPA's 303(d) list of impaired waters. The following pollutant sources were evaluated for each lake or stream: watershed runoff, loading from upstream waterbodies, atmospheric deposition, lake internal loading, point sources, feedlots, septic systems, and in-stream alterations. An inventory of pollutant sources was used to develop a lake response model for each impaired lake and a load duration curve model for each impaired stream. These models were then used to determine the pollutant reductions needed for the impaired waterbodies to meet water quality standards. The findings from this TMDL study will be used to aid the selection of implementation activities as part of the Crow Wing River Watershed Restoration and Protection Strategy (WRAPS) process. The purpose of the WRAPS report is to support local working groups and jointly develop scientifically-supported restoration and protection strategies to be used for subsequent implementation planning. Following completion, the WRAPS report will be publically available on the MPCA Crow Wing River Watershed website
