Our summer of water quality testing has come to a close. See the Rogue basin's water quality report card here!

We spent the summer collecting 140 samples from streams, rivers, and reservoirs in the Rogue basin to monitor popular waterways for safe swimming. Many of our favorite recreation sites were safe this summer for swimming, fishing, and boating, but a few sites stood out as problematic for healthy water quality and safe recreation. See the full season recap here.
