Keatons Lake HAB Notice: Keatons Lake is under SWIM ADVISORY Until Further Notice due to Harmful Algal Bloom (HAB) Conditions.

 It is recommended that people and pets should refrain from swimming, kayaking, paddleboarding, or any other activity with a risk of water contact. Members use at their own risk.

Results from the most recent testing (10/08/2026) indicated that the Cumberland Beach sampling location had a moderate amount of microsystis sp. at 21,300 cells/ml. Microsystis is a potential toxin producing cyanobacteria.

Including the rest of the sampling sites, the average potentially toxic cyanobacteria concentration in Keatons Lake was 10,600 cells/ml.

Keatons Lake will remain under SWIM ADVISORY until further testing results support a change in status.

Actions Currently Underway:

Water Quality Testing: As part of our ongoing monitoring program, LOWA will conduct follow-up sampling including algal toxin testing.

Treatment Planning: LOWA is working with our environmental partners to move forward with treatment as quickly as possible. Preparations are occurring concurrently with testing so that treatment can begin promptly.

Continued Monitoring: Water sampling will continue throughout the response process. Algae cell concentrations and toxin levels will be monitored through follow-up testing until results indicate it is safe to lift the swim advisory conditions.

We will continue to keep the community informed as we monitor progress and await post-treatment results.
