Town of Richmond update on plans for Mill Creek & Outlet Creek.


Sunday June 16, 2024 Honeoye Lake Water Quality


Surface Water Temperature: ~71.2 F

Water Clarity: ~10.0 Feet

Lake Level: 803.2 Feet above sea level 

Observations: Sunday (6/16/24), Water clarity was ~10.0 about 3.2 feet lower than last Monday.  This significant drop in water clarity from last Monday was due to a noticeable visual increase of algae in the water column.  Since today had sunny skies our water clarity reading should be accurate. The surface water temperature increased ~2.7 F to ~71.2 F from last Monday due to the warmer weather we have had over the last week.  It was again a very nice sunny early summer day with light wind on Honeoye Lake!


We found Gloeotrichia (lots of small spikes) of varying intensities today both in near shore areas and open water in the water column.  However, we did not see any surface scum at the five near shore sites we checked today.  We also found sparce amounts of Anabaena (Dolchospermum) (looks like a spring) too.  Anabaena usually shows up in mid-July.  So, it is about a month early.  You should be watchful for Gloeotrichia and Anabaena blooms lake wide.  These are both blue-green algae species.  Expect to see Gloeotrichia and Anabaena blooms over the next few weeks particularly when we have 80-90 F days with calm winds.  The weather forecast is for high temperatures in the low ninety’s next week.  See pictures below:  More information on Gloeotrichia and Anabaena can be found at: 

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:



Muller Field Station Honeoye Inlet European Frogbit Pulls Summer 2024

An emergent population of European frogbit (Hydrocharis morsus-ranae), an undesirable invasive species, was first detected in the Honeoye Inlet last summer.  In hopes of curtailing this population from further spread, Muller Field Station is hosting three community pulls/monitoring surveys this summer in partnership with Finger Lakes Partnership for Regional Invasive Species Management (PRISM) and New York State Department of Environmental Conservation (DEC). Canoes, paddles, and life jackets provided. Plan to arrive 15 minutes prior to start time to account for parking, getting prepped for paddle, etc.  Come prepared with water, lunch, and proper attire to paddle- rain or shine. Events will be cancelled in event of thunderstorms.  Limited number of participants will be accepted for each event. A separate registration form is required for every participant.  Please RVSP no later than two days before scheduled event using the link below: 

Wednesday June 5th, 10-1pm

Friday Jun 21st, 10-1pm

Wednesday July 3rd, 10-1pm

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.

Review complete details in the Big Panfish Initiative Study Plan, 2021-2026 (PDF)
