Surface Water Temperature: ~78.3 F
Water Clarity: ~7.3 Feet
Lake Level: 803.0 Feet above sea level
Lake Level Relative to Weir: -0.5 Feet
Observations: Monday (7/25/22), The water clarity has increased ~0.7 feet to ~7.3 feet and the surface water temperature was increased ~1.5 to ~78.3 F over the last week. The lake had restratified again by last Thursday. This was unusually quick as it usually takes a week or longer to restratify.
There was visible algae in the water column at most of our HAB monitoring locations. It looks like green dots in the water column. We did not see any areas with surface algae scum.
We took the images of today’s Anabaena and Gloeotrichia algae samples below using a high-powered microscope. For more information on Anabaena and Gloeotrichia see the articles at HARMFUL ALGAL BLOOMS | Honeoye Lake (honeoyelakewatershed.org) or search the internet for information.
The DEC recommends that you, your family, and pets avoid contact with water that contains a blue-green algae bloom like Anabaena and Gloeotrichia. Everyone should be very careful to watch for blue-green algae blooms for the next few weeks.
As of last Thursday (7/22/22) the lake was restratified again. This was unusually quick as it usually takes a week or longer to restratify. You can see this by the divergence of the temperature and dissolved oxygen graph lines for the various depths on the left. Today (Monday 7/25/22) the dissolved oxygen at 7 m (23.1 feet) was only 0.81 mg/L low enough to weaken the phosphorus iron bond releasing phosphorus into the deep bottom water again. About 550 acres of bottom sediment is 7 m or deeper. Surface water temperature was ~78.3 F and bottom water temperature was ~71.8 F. 1-meter equals 3.3 feet.
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:

The Town of Richmond has obtained an emergency DEC permit to dredge the shale and sediment deposits out of Mill Creek from just behind the Mill Creek Café to the 20A bridge and under the 20A bridge in the NYS DOT Road right away. Last week (Week of July 18th) they started installing large rocks on the Mill Creek stream bank, south of the Mill Creek Café, to prevent erosion. This week they intend to install more large rocks along Mill Creek’s stream banks. See attached pictures. This project should reduce flooding risk from Mill Creek in the Hamlet and lessen the negative impact Mill Creek is having on the Outlet Creek flow. Richmond is working on a long-range plan to address other stream flow issues in the Outlet Creek and Mill Creek. We will keep you posted.
