Diamond Lake Total Maximum Daily Load (TMDL) Implementation Plan

Diamond Lake is a 1,607 acre lake, located in east-central Kandiyohi County in west central Minnesota. The outlet from Diamond Lake is controlled by a fixed crest dam, constructed in 1952, which is owned by Kandiyohi County. Water leaving Diamond Lake flows into a public drainage system into the Middle Fork of the Crow River, the Crow River, and eventually the Mississippi River. Diamond Lake is about 6 miles northwest of Atwater and 12 miles northeast of Willmar, Minnesota. Diamond Lake is the focus of a Total Maximum Daily Load (TMDL) study lead by the Middle Fork Crow River Watershed District (MFCRWD). The MFCRWD retained Houston Engineering, Inc. (HEI) to assist with technical activities necessary
to complete the TMDL study. The key component of the TMDL report in terms of future activities designed to bring the lake into compliance with water quality standards is the Implementation Plan. This document serves as a request for Minnesota Pollution Control Agency (MPCA) approval of the Diamond
Lake TMDL Implementation Plan. The full TMDL report has been submitted to the MPCA; as of the date of this request, EPA approval is pending. The full report is also available upon request.
