Public Beaches
Between Memorial Day and Labor Day, Public Health monitors local designated swim beaches to determine if the water quality is safe for swimming and recreation. If there is a problem with algae or E.Coli bacteria in the water, advisory signs will be posted at the lake.
Whether there is an advisory in effect or not, always take precautions such as not swallowing water, exposing cuts or sores to water, or entering water that appears scummy. Please read below for a description of our monitoring process.
Current beach information
Below you will find current advisories for lakes that have designated swim beaches monitored by Clark County Public Health. Health concerns observed at other locations will be added when warranted.
| Swim Beach | Advisories | Comments |
|---|---|---|
| Battle Ground Lake | None | Last sampled 6/19/17 |
| Klineline Pond | None | Last sampled 6/19/17 |
| Vancouver Lake | None | Last sampled 6/19/17 |
Bacteria water sampling
Harmful bacteria can be present in lakes and occasionally in rivers and streams. Ingesting water contaminated with fecal bacteria can cause fever, diarrhea, and vomiting. If you experience these symptoms after water contact, please contact your physician. To reduce your risk of exposure, Public Health recommends showering and hand washing with soap and warm water after contact with water at swim beaches.
Every other Monday, Clark County Public Health collects several water samples from Battle Ground Lake, Klineline Pond, and Vancouver Lake to test for E.coli. This is based on the federal Environmental Protection Agency's recommendations for fresh water monitoring. If a single sample has a maximum level above 235 colony forming units (cfu), then Public Health takes action to warn swimmers. Expect updates the following Thursday or Friday.
Toxic algae monitoring
Algae blooms can pose significant health risks to humans and animals in lakes or other water bodies without currents. Algae blooms are most common in summer but can also occur at any time of year. Toxins produced by blue-green algae may be present during a visible bloom or may persist after a bloom has disappeared. Blooms can also be produced by other algae species that are not harmful.
In the event of a bloom, Public Health staff will take samples of the lake water to determine if toxins are present. Monitoring will continue as needed and signs will be posted at the swim beach to discourage activity in the water.
