Baboosic Lake Town Beach

• For more information about the Town Beach, including Beach and Boat Pass information, please look HERE 

The ARD tests the water quality at Baboosic Lake Town Beach on a bi-weekly basis.  

6/16/2025 - Fecal
Deep 7.5 MPN
Shallow 23.1 MPN

6/30/2025 - Fecal
Deep 33.6 MPN
Shallow 39.9 MPN

7/14/25 - Cyanobacteria
17,500 cells/mL

7/22/25 - Cyanobacteria
19,600 cells/mL


FECAL - State Standards state that the beach must be closed if a single test goes above 88 MPN per 100ML or if both tests exceed 158 MPN per 100ML.

CYANOBACTERIA - Warnings are issued when the cyanobacteria cell density exceeds the recreational health threshold of 70,000 cyanobacteria cells/mL. This density is associated with the level at which cyanotoxins may be present at a concentration that threatens public health. When there is a warning, NHDES advises lake users to avoid contact with the water in the vicinity of a bloom. Pets and livestock should also be kept out of the water. When NHDES issues a warning, lakes are resampled weekly until the bloom subsides. NHDES issues warnings from May 15 through October 15.
Watches (alerts) are issued 1) based on a photo submitted before NHDES can analyze a sample and a bloom that may be health risk is evident; 2) when the cyanobacteria cell density is approaching but does not yet exceed 70,000 cells/mL; or 3) if a bloom is reported, but conditions may have changed. Watches are intended to serve as statements to be on the watch for a potential cyanobacteria bloom. A watch may develop into a warning but otherwise remain active for a week. Resampling only occurs if further bloom reports are submitted. Watches are issued year-round as needed. Waterbody users should avoid contact with bloom material and keep pets and livestock out of the water.
