Clark County Beach Water Quality Tests
Clark County beaches and swim areas are tested for E. Coli by the Clark County Health Department. The results of these tests are passed along to the Clark County Forestry and Parks Department where they are placed on this website for public knowledge. Samples are typically taken on a Monday with results coming back mid week. If a sample comes back elevated, a re-test is completed. If the re-test sample comes back elevated, notifications are posted below and appropriate warning signs are placed at the location of the elevated sample.

What Does Each Advisory Mean?
No Advisory means that the current E. coli levels in the water are considered normal.
Yellow Advisory means that the current E. coli levels in the water are elevated higher than normal and an increased risk of illness may be present. Users should swim at their own risk. Make sure you do not ingest the lake water. Shower after swimming. Wash hands before eating and do not swim if you are ill.
Red Advisory means the beach is currently closed because the current E. coli levels in the water are extremely elevated and serious risk of illness may be present. Users should not be using the beach because it is closed.
Algae Advisory means that the local health department has determined that this lake is currently experiencing visible levels of Algae. Local health officials cannot easily determine when algal toxins are being produced or are present. Anyone considering recreation on or in the water should use practice their best judgment. Please visit this DNR website for more information on the potential harm of this algae.
What Causes An Elevated E. coli Level?
The actual source of these E. coli are unknown. In Fact, they likely originate from a multitude of possible sources, including human waste, bird droppings, agricultural run off, or even naturally occurring E. coli present in the soil.
