Water quality monitoring at local lakes
Before visiting a local lake, be sure to check for water quality advisories. Public Health monitors water quality at designated swim beaches and other waterbodies throughout the summer to determine if the water is safe for swimming and recreation.
Public Health collects water samples from Vancouver Lake, Klineline Pond and Battle Ground Lake to test for bacteria that can make people sick. Public Health also monitors the swim beaches and other local lakes, including Round Lake and Lacamas Lake, for harmful algal blooms. The algal blooms can release toxins that can make people sick and deadly for dogs.
Public Health issues advisories if waterbodies are unsafe for swimming and recreation. Visit the Current Advisories webpage for the latest information.
Bat season is here
Bats are the primary animal that carries rabies in Washington. During the spring and summer, when they’re most active, people may be more likely to find one in their living spaces.
Never touch a bat with bare hands and teach children to never touch them. People who think they may have been bitten, scratched, or had direct contact with a bat should make sure they’re no longer in the same space as the bat. If possible, close the doors and windows to the room where the bat is located. Then call Clark County Public Health.

Reduce mosquito breeding
Warm weather brings mosquitoes – and the diseases they can spread. Taking a few minutes to remove standing water around the yard can help reduce mosquito populations in the neighborhood.
Drain water from old tires, flowerpots, buckets, tarps, and wheelbarrows. Refresh water in bird baths, ponds, wading pools, pet bowls, and animal troughs at least twice a week. Repair leaking faucets and sprinklers, clean out gutters, and keep swimming pools properly maintained. Remember to check hidden spots, such as under bushes, for containers or debris that can collect water.
Choose permitted vendors
Choosing to buy food from a permitted vendor means the food was prepared in a kitchen with equipment and facilities needed to safely prepare food. It also means the staff preparing the food have received food safety training, and the kitchens are being regularly inspected by Clark County Public Health.
Before buying food from a vendor, look for a posted permit or ask to see the permit. If they don’t have a permit, don’t risk it. Choose to buy from a permitted vendor taking steps to keep food safe.
