Shoreline Monitoring for Harmful Algal Blooms (HABs)

Seneca Lake Pure Waters Association is diligently working to develop and implement a Harmful Algal Bloom (HABs) identification and notification process for Seneca Lake. Our Shoreline Monitoring program began in 2014 with a simple phone number, the HABs Hotline. In just four short years, the program has evolved into a successful collaboration with the New York State Department of Environmental Conservation (NYS DEC) and Finger Lakes Institute (FLI) at Hobart and William Smith Colleges.

Seneca Lake Pure Waters Association is expanding the depth and breadth of the Shoreline Monitoring program by:

• Increasing the number of Shoreline Survey Volunteers.
• Adding more monitoring zones to the shoreline to ensure maximum survey coverage.
• Raising awareness about HABs by incorporating HABs education in publications and forums.
