No HABs on Canandaigua Lake yet

  • Staff Report 

Canandaigua Lake, overseen by the Canandaigua Lake Watershed Association (CLWA), is currently clear of Harmful Algal Blooms (HABs), according to 62 volunteer monitors.


The clarity of the lake is reportedly in good condition, with an average weekly depth of six meters, as observed through visual assessments and Secchi disk measurements. Despite the appearance of murky greenish water and plant fragments near the City Pier, CLWA officials have confirmed these instances are not HABs.

In addition to HAB monitoring, CLWA volunteers are partnering with the Finger Lakes Institute to control the spread of invasive water chestnuts in the West River, located at the southern end of the lake. The aggressive aquatic plant can form dense mats that threaten the aquatic ecosystem by blocking sunlight and reducing oxygen levels.
