Condition: FAIR (2021) Source
- 5-Year Average Trophic State: 50/becoming Eutrophic
- Secchi Disk: Average summer reading 5 ft. (SE Georegion average 7.1 ft.)
Typically the summer (July-Aug) water was reported as MURKY and GREEN. This suggests that the secchi depth may be mostly impacted by algae.
Average summer Chlorophyll 14.1 µg/l (SE Georegion average 20.9 µg/l).
Average summer Total Phosphorus 36.2 µg/l.
May experience noticeable algae blooms.
- Trophic State Index (TSI): 55/Eutrophic. What does this mean? Lakes becoming eutrophic: decreased clarity, fewer algal species, oxygen-depleted bottom waters during the summer, plant overgrowth evident, warm-water fisheries (pike, perch, bass, etc.) only.
