Have you seen the new signs? Starting today, you'll see new benthic algae mat educational signs popping up at parks, marinas, and docks along the Columbia River. Benthic algae mats produce the same toxins as the blooms seen in the lakes, but grow attached to the bottom of a body of water instead of "blooming" on the surface.
Hydration Safety!
When you're outside having fun, you can easily forget to drink water. Drinking water is the easiest and most important thing you can do to prevent heat related illnesses like dehydration, heat exhaustion, and heat stroke. Always remember:
Hydrate before and after activity
Hydrating more frequently at smaller quantities is most effective
