San Juan below Navajo Dam, year round. A tailwater that stays in the forties all year, so it fishes when everything else is frozen or blown out. Tiny flies: midges size 22 to 26, baetis 20 to 24, and annelids, red or pink, size 10 to 14 in the deeper water. Eggs in the fall when browns spawn. Long leaders, light tippet, and a good drift beat everything else. Flows change with dam releases, so check the gauge the morning of.

The water needs a good week or two to clear up from all this moss and gunk floating down the river, especially wading above Texas Hole. Other than that, the hatches have been nice and the fish have been feeding.
