Monday May 23rd, 2022 Honeoye Lake Water Quality Report

Surface Water Temperature: ~68 F

Water Clarity: ~10.8 Feet

Lake Level: 803.9 Feet above sea level

Lake Level Relative to Weir: +0.4 Feet

Today was a beautiful day to be out enjoying Honeoye Lake!

Observations: Monday (5/23/22), The water clarity has decreased ~1.7 feet to ~10.8 feet and the surface water temperature has increased ~4.0 F to ~68 F over the last 4 days. The decrease in water clarity in the southern lake basin and increase in lake level was probably caused be the 0.5 inches of rain we got in two hours Saturday night. The lake was stratified (had a thermocline) between 16.5-20 feet deep today. It is very unusual to see the lake stratified in mid-May. However, there was still a high level of dissolved oxygen in deep water near the lake bottom keeping phosphorus bound to iron.

We did not visually see any signs of an algae bloom today.

Always use your own visual assessment before making contact with the lake water at this time of year as the blue-green algae situation can change daily if not hourly. Please regularly check the DEC HABs alert map for more detailed updates on Honeoye Lake HABs alerts:
