Note on Advisory Signs

For those who visit our beaches, you will notice that the Algal Warning Signs are posted. These warning signs were posted due to readings taken on 8/21/17 which indicated algal toxin levels exceeded the EPA’s Public Health Advisory limit.

While the most recent tests indicated the algal toxin levels were well below the Elevated Advisory Limit, 2 readings under state guidelines are needed before the signs will be taken down.

Microcystin Algal Toxin   E.coli Bacteria
West Beach 1 East Beach 2   West Beach 1 East Beach 2
Results below early warning level Results above early warning level   Results below early warning level Results below early warning level

The Algal Toxin Levels from the Beach 2 slightly exceeded the EPA’s Public Health Advisory limit. However it is well below the Elevated Advisory Limit which would recommend no contact. All data can be found on the LMC section of the RRA website.

Current Conditions for Week of 8/28/2017: The current results for the testing program for the lake are summarized above. A green cell indicates that results are below the USEPA or OhioEPA criteria for recreational water. A yellow cell indicates that values have exceeded the limit and appropriate caution is advised. Your Lake Management Committee’s (LMC) water testing program for harmful algal blooms (Microcystin) monitors our two beach areas monthly during the hot, summer months and advises that all test results received so far have been well below any level of concern or alarm. In addition, the LMC is also having tests performed for the presence of E.coli bacteria weekly at the two beaches as is done in most public beaches. Should any of these test results approach the level of caution, the Board of Directors can request that caution signs be posted at the affected beaches for your safety. Of course, common sense tells us not to swim in any waters that contain unusual amounts of algae. Please enjoy our beautiful lake and have a safe summer.
