Condition: POOR (2020) Source
- 5-Year Average Trophic State: 63/Eutrophic
- Secchi Disk: Average summer reading 5 ft. (SE Georegion average 6.5 ft.)
Summer (July/Aug) water was reported as MURKY and GREEN.
Because of low chlorophyll levels, this suggests readings may have been impacted by suspended marl (versus algae).
- Chemistry:
Average summer Chlorophyll 5.1 µg/l (SE Georegion average 21.7 µg/l).
Average summer Total Phosphorus 154 µg/l.
Lakes that have more than 20 µg/l and impoundments that have more than 30 µg/l of total phosphorus may experience noticeable algae blooms.
- Trophic State Index (TSI) in 2020: 47/Mesotrophic. What does this mean?
Mesotrophic lakes are characterized by moderately clear water, but have an increasing chance of low dissolved oxygen in deep water during the summer.
