Condition: GOOD (2021) Source

  • 5-Year Average Trophic State: 45/Mesotrophic
  • Secchi Disk:  Average summer reading 13 ft. (SE Georegion average 7.1 ft.)
    Typically, the summer water was reported as clear and BLUE.

graph of water clarity readings in the high single digits and low teens since 2014.

  • Chemistry:
    Average summer Chlorophyll 2.9 µg/l (SE Georegion average 20.9 µg/l)
    Average summer Total Phosphorous 16.5 µg/l.
    Lakes that have more than 20 µg/l total phosphorus may experience noticeable algae blooms.
  • Trophic State Index (TSI): 43/Mesotrophic. What does this mean?
    Mesotrophic lakes contain moderate amounts of nutrients, and contain healthy, diverse populations of aquatic plants, algae, and fish. Occasional algae blooms may occur. Mesotrophic lakes are characterized by moderately clear water, but have an increasing chance of low dissolved oxygen in deep water during the summer.
