Toxic blooms were identified throughout September along shoreline properties in nearly a dozen towns on the lake including Geneva.

Two upcoming forums will reveal the latest regarding toxic blue-green algae on Seneca Lake. During August and September, over 100 volunteers monitored 75 zones covering over 55 miles of the lake’s shoreline for a 10 weeks to identify harmful algal blooms (HABs). Lab results indicated all of the blooms produced microcystin, a toxin that potentially causes liver damage. Toxic blooms were identified throughout September along shoreline properties in the towns of Benton, Fayette, Geneva, Hector, Lodi, Milo, Ovid, Romulus Starkey, Torrey and Varick.

Seneca Lake Pure Waters Association partnered with Finger Lakes Institute and the state Department of Environmental Conservation in identifying HABs on the lake.

The forums will discuss water quality and give results of SLPWA 2018 Shoreline Monitoring program that identified HABs.

The forums will cover the following:

Seneca Lake Water Quality Trends

Presented by John Halfman with Finger Lakes Institute, Halfman will discuss Seneca Lake’s water quality trends over the past 25 years with an explanation of how Seneca Lake water quality compares to the other Finger Lakes. He will also give a summary of possible threats to water quality going forward.

HABs in the Finger Lakes

Presented by Lewis McCaffrey (DEC Finger Lakes Water Hub), he will discuss how, where and why the DEC helps set up volunteer organizations for monitoring HABs in NY. He will provide an overview of action plans being developed to combat HABs in the Finger Lakes.

Water Quality Improvement Actions

Presented by Dan Corbett with SLPWA, he will look at what actions Seneca Lake Pure Waters Association is taking to protect the water quality of Seneca Lake.

The public is invited to attend the forums, on Nov. 8 at the Ramada Geneva Lakefront, and on Nov. 12 at the Watkins Glen Performing Arts Center. Doors open at 6 p.m. for each forum. Register to attend by visiting:
