Check the water temperature first.

Water temperature is unconfirmed. Use a stream thermometer; stop trout fishing at 70°F or warmer, or sooner if fish show stress.

Why this recommendation?

USGS shows 125 cfs. The flow has been stable over about 6 hours. USGS marks this reading provisional and may revise it. USGS records for this date (1936-2025, 90 readings) show a typical middle range of 56 cfs to 190 cfs. Flow is within the typical range for this date, so weather, temperature, and access become the next checks.

Methods, fish species and trip notes

How to fish San Juan at Pagosa Springs today.

Summer mornings and early fall are the best practical windows. Spring runoff and high tubing flows can make fishing less useful even when access is easy.

Low and clear

Use small dries, light nymphs, and careful approaches around visible fish.

Moderate town flow

Best blend for short nymph rigs, dry-droppers, and edge fishing.

High recreation flow

Fishing may be less practical around tubing and fast water.

Warm afternoon

Fish early and quit if trout handling becomes stressful.

Wading, bank fishing or floating?
Access choicesNo single best option

Wading and Bank fishing have the same top score. Use current access, footing, weather, and local rules to choose.

Wading92/100

Wading is in play only where your chosen access has clear footing, legal entry, and no forced crossings.

Bank fishing92/100

Bank and edge fishing remains a practical low-commitment option if access is legal and footing is safe.

FloatingNot recommended

This report does not recommend floating this reach.

Check these before you choose a reach.

Best flows

Clear, moderate flows that leave fishable edges without heavy tubing pressure.

When to leave

Skip during high runoff, heavy town recreation, dirty water, or warm low-water afternoons.

Local plan

Check the gauge and public access in town, fish early, then move to the Piedra or Animas if the town reach is crowded.

Backup water

Piedra River is the best nearby change-of-pace when town access or recreation pressure limits the San Juan.

Yamaguchi Park and town river area

Useful for scouting public river use and crowding before fishing.

  • Use designated public access locations and avoid crossing private or closed banks.
  • Expect tubing and general river recreation during warm weather.
  • This is not the New Mexico San Juan tailwater. Check the right report and license for Navajo Dam water.

If this water does not fit the day, check another report before you start the drive.
