This week, we chat with Bob Irvin [Interview starts at 42:00], president of American Rivers, an organization that does solid work protecting the aquatic resources we all love. Bob and I talk about the Clean Water Act and the Clean Water Rule--what these laws have done for us in the past, how they are currently managed, and threats to their effectiveness. It's not as much fun as talking about trout or steelhead, but it's important stuff to all of us.

In the Fly Box this week, listeners offered the following tips and questions:
