The San Juan below Navavo Dam, New Mexico is doing a spring release, currently flows are around 4,000 cfs and will continue to rise until somewhere sround 5,000. Heads Up Flyfishing will only be offering float trips through the high water period due to the dangers of wading at these increased levels. The only time I'd discourage fishing is on days they increase the flow. Once it's had a day or so to level out, the fishing will be fine. We'll be throwing lots of worms, eggs, and leeches at the beginning of the flush; then moving back to the smaller more realistic bugs as the fish become more accustomed to the heavy water. Fish will be found concentrated in seams where they can avoid the main current.
