Sunday July 14, 2024 Honeoye Lake Water Quality
Surface Water Temperature: ~81.0 F
Water Clarity: ~9.6 Feet
Lake Level: 803.5 Feet above sea level
Observations: Sunday (7/14/24), Water clarity was ~9.6 about 0.6 feet lower than Monday 7/8. Even though it was sunny this morning there was a lot of Gloeotrichia visible in the water column reducing water clarity, The surface water temperature increased ~1.7 F to ~81.0 F from Monday 7/8 due to the warmer weather we have been having recently. It was a very nice day to be out on Honeoye Lake!
We were able to check most of our regular near shore locations around the lake for blue-green algae blooms today. We visually could see Gloeotrichia, a blue-green algae, of varying intensity at all the locations that we checked today. See picture on the left: We did not see any Gloeotrichia surface scum today. The Sandy Bottom Park Swimming Beach is currently closed due to a blue-green algae bloom. Since there is 10 miles of Honeoye Lake shoreline there is likely to be several other locations currently experiencing blue-green algae blooms this week. Please regularly check the DEC HABs alert map for more detailed updates on Honeoye Lake HABs alerts:
We found Gloeotrichia (lots of small spikes) today both in near shore areas and open water in the water column. Also, found Aphanizomenon (looks like a leaf) and Anabaena (Dolchospermum) (looks like a spring) in today’s algae sample. These are all blue-green algae species. Expect to see Gloeotrichia, Anabaena, Aphanizomenon blooms lake wide over the next few weeks particularly when we have 80-90 F days with calm winds. See pictures on the left and below: More information on Gloeotrichia and Anabaena can be found at: https://www.honeoyelakewatershed.org/habs
Several research studies have found that most of the phosphorus that fuels Honeoye Lake’s blue-green algae blooms is released from the lake bottom sediments when the lake’s dissolved oxygen level goes below 0.50 mg/L in the deeper parts of the lake. The dissolved oxygen (DO) level near the lake bottom at ~7.0 m (~23 feet) was ~0.28 mg/L today. So, phosphorus may currently be released from the bottom sediments. This potential release of phosphorus from the bottom sediments could fuel blue-green algae blooms of Anabaena and Microcystis, which depend on phosphorus being in the water column, when the lake mixes again. The lake has stratified again at 6 m (~20 feet). Today’s temperature and dissolved oxygen graphs are on the left.
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:

DEC Big Panfish Initiative (BPI)
The Big Panfish Initiative (BPI) was developed to create destination fisheries for larger size panfish in select waters including Honeoye Lake. The BPI is an experimental program that is being conducted to determine the impacts of lower harvest and minimum size limits on sunfish population age and size structure in select lakes throughout New York and to evaluate the level of angler satisfaction with this management strategy. It also includes an assessment of crappie population age and growth characteristics in select waters to determine if those waters have the potential to yield larger fish under more conservative harvest regulations.
