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 clear skies (about 2% 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.

These are probabilistic fishability odds, not a guarantee. We build them from live USGS streamflow, each river’s published fishable-flow band, the curated season, and a moon/solunar model — flow and weather can change fast, and even a perfect flow on the right moon can fish slow. Some prime days disappoint; some marginal ones surprise. How we compute the score.
