It Is Safe to Swim!!!

 We have received the lab report, and the levels of Blue Green Algae in Clementia are within acceptable parameters, so you can enjoy the reservoir on this hot weekend!

Clementia is undergoing chemical treatment for the blue-green algae and swimming is still prohibited. Follow up treatment will continue next Monday as well due to the vendors limited supply of on hand chemical for the treatment process. We apologize for the inconvenience this has caused and remind everyone to please be safe.

Cyanobacteria (blue green algae) has been spotted in Clementia Reservoir. Humans (and pets) can be exposed to the harmful algal blooms through accidental ingestion while swimming, by inhaling water spray (aerosols) during water recreation (such as boating), or by being in the water where a bloom is occurring. Your best bet is – “When in doubt, best keep out!”. While swimming and direct reservoir contact is allowed for Clementia Reservoir , it is advisable to avoid water where a visible blue-green algae bloom is present. The Reservoir is scheduled to be treated as soon as possible in order to prevent the expansion of the cyanobacteria and to proactively protect our water supply.
