Elk River Watershed Association Phase I TMDL Report Elk River Bacteria and Turbidity TMDL Big Elk Lake and Mayhew Lake Nutrient TMDLs

2009-01

The Minnesota Pollution Control Agency (MPCA) listed Mayhew Lake and Big Elk Lake as impaired for Excess Nutrients (phosphorus) and Elk River reach 579 as impaired for fecal coliform bacteria (now E. coli) and turbidity. The impaired water bodies addressed in this TMDL are within the Elk River Watershed. All three water bodies are addressed in this study because: 1) they are all located within the Elk River Watershed and 2) the turbidity impairment in the Elk River is likely driven by algae resulting from nutrient impairments in the headwaters lakes (Big Elk Lake); thus, nutrient loading analysis proposed for the lake nutrient TMDLs will assist in quantifying the portion of the turbidity impairment due to algae.
