Lakes and Rivers Monitoring Information
Are Washington lakes and rivers safe to swim in? Who is checking to make sure?
The risks associated with swimming in natural waters include:
Washington State does not have a statewide program to monitor freshwater swimming beaches for public health. An EPA grant fully funds the BEACH Program. One of the grant requirements is we spend the money on saltwater (marine) beaches.
If individual counties or cities have the resources, they may monitor the water quality of some lakes and rivers. They may test for fecal bacteria and/or harmful algae blooms.
Click on your county to find out who is monitoring your lake or river.
