Conditions & the best window
The prime bite is dawn and the last hour of light, strongest around the new and full moon. Today's sky on the San Juan River looks partly cloudy (about 37% cloud) — and an overcast day can actually keep fish looking up. Watch the flow as much as the sky: a sharp change in discharge, up or down, can turn the fish off for a day.
The Texas Hole and the braids below the dam are legendary; much of the Quality Waters is wadeable, though a guided drift puts you on the deeper runs. Steady dam releases mean it rarely blows — watch for the prime 500–1,000 cfs window.
