When people think of fly fishing the San Juan river, they usually think of the hugely popular stretch below Navajo Dam. Or the fun pocket water that runs through Pagosa Springs. However, between those two locations lies miles of rarely fished water that flows through private and tribal lands. This is where the working family ranch known as the Diamond M Bar Ranch is located. This unique stretch of the San Juan holds fish year round and serves as a corridor for wildlife traveling through the area.
