San Juan River Fly Fishing in Summer

San Juan River at Pagosa Springs. Guides and local shops report an ideal wade-fishing window of roughly 150–800 cfs (Upper San Juan WEP angling study (2021), Table 11). That's the general year-round read on this gauge; conditions in summer specifically vary with runoff timing and reservoir releases, so check the live gauge below before you go.
