Redirecting to NWToxicAlgae site...
Magnuson off-leash area is not a swimming beach and has no lifeguard on duty. This site is no longer monitored for fecal coliform bacteria as elevated bacteria appeared to be associated with dog activity in the water. However, the site is still monitored for algal toxins as pets are at risk if there is a toxic algae bloom present. For more information about algal toxins in lake water check out the State Department of Health Cyanotoxin web page.
