Diamond Lake Total Maximum Daily Load Project (MPCA Contract)

  • Contract timeline February 2008 – June 2011
  • Contract amount: $176,215
  • In 2006, Diamond Lake was added to the Minnesota Pollution Control Agency’s (MPCA) impaired waters list for excess nutrients, specifically total phosphorus. This means that the amount of nutrients in the lake can cause nuisance algae blooms along with other problems which detract from the lake’s designated use of recreation. In 2008, the Middle Fork Crow River Watershed District entered into a contract with the MPCA and retained a consulting firm to carry out a Total Maximum Daily Load (TMDL) study, the goal of which is to identify the sources of the excess nutrients.
