Watershed Summary  

The Mona Lake watershed is approximately 140 square miles and consists of Mona Lake, Black Creek, Little Black Creek, and several smaller tributaries.  Land use includes a mix of agriculture, business, industry, residential, and forest.  Primary pollutants include nutrients, stormwater runoff, sedimentation, and contaminated sediments.  The Mona Lake watershed is relatively small, but it has some of the most serious water quality challenges in west Michigan; Mona Lake and both its major tributaries require TMDLs.  The Mona Lake Watershed has two watershed plans.  One developed under the Phase 2 Storm Water Program (accepted by the Storm Water Program and approved under CMI) and another developed through the Nonpoint Source Program (approved under both CMI and 319).
