See if you can find all 6 spots where mussels can be found after being submerged in water!

Even if your equipment is in the water for a single day, you can still transport microscopic young invasive mussels if you do not follow the protocol of cleaning, draining, and drying your equipment before entering a different body of water.

💧 August is National Water Quality Month.

Did you know that stormwater is not treated before it reaches your local waterways? That means everyday pollutants like litter, pet waste, vehicle fluids, and yard chemicals can run off during storms and directly impact water quality. The good news? Small actions make a big difference.

This month, take simple steps to help keep California's waterways healthy:

• Properly dispose of trash and recycling
• Maintain your vehicle to prevent leaks
• Pick up after your pets
• Choose less-toxic products for your yard

Want to beat the heat out on the water? Let's leave golden mussels at home. Despite being as small as a nickel, they can rapidly multiply and impact the environmental stability of our waterways. Keep them out of the Russian River Watershed by properly cleaning your boat, paddleboard, kayak, or canoe after recreating in other places, and by stopping by one of the mussel inspection stations before going out on the water!
