We are removing the yellow alert for caution on Cyanobacteria blooms. There are no NHDES red advisories or yellow alerts for Lake Kanasatka effective at this time.


We ask everyone to please continue to monitor conditions in your area, and if you see anything of concern or significant changes, please notify the Rapid Response Team and/or the Water Quality Chair (links on Kanasatka.org website).


The lake was last tested Sunday, with low cell counts. We communicated the release of the NHDES red advisory status on 9/21 when the results of Sunday’s samples were verified, and our status was dropped to yellow alert at that time. Another sample taken on Tuesday was found to have relatively high cell counts, but has been considered an isolated occurrence and not widespread. We have not seen or gotten reports of any bloom accumulations in the past several days.

Update on Watershed Management Plan

The development of the Watershed Management Plan (WMP) for Lake Kanasatka made great progress over the summer. The plan’s developer, FB Environmental Associates, completed significant work on the watershed and shoreline surveys. The watershed survey assesses run-off management and infrastructure, inlets to the lake and other observations.The shoreline survey involved assessing conditions of waterfront parcels including levels of erosion, bare soil, and vegetation. The slope of the land and distance to shore of dwellings was also noted. The WMP Steering Committee will be working on a communication plan to share this information with individual property owners.

Several potential projects were identified and will be discussed with the Technical Advisory Committee in late October. Those which clearly bring an immediate benefit will be discussed to see how and when they can be implemented. Later in the year or the first part of 2022, comprehensive modeling of how to reduce phosphorus loading, thus reducing the opportunities for cyanobacteria blooms, will be ready for review.

Additionally, the NH Department of Environmental Services updated a new bathymetric (depth) map and performed sediment core sampling. LKWA is awaiting the analytical results.

To date, the plan development is on schedule to be completed by June 2022.
