What's swimming in the San Juan River
- This entry covers the Colorado stretch of the San Juan near Pagosa Springs, not the well-known New Mexico tailwater below Navajo Dam.
- Pagosa Troutfitters rates Rainbow Trout as "high" probability given a long stocking history, Brown Trout as "good" probability, Brook Trout possible in tributaries, and San Juan-lineage Cutthroat Trout as native but conservation-sensitive and not a typical catch (Pagosa Troutfitters).
- AvidMax confirms Brown Trout as the dominant catch, typically 12 to 16 inches, with seasonal Kokanee Salmon runs in the fall (AvidMax).
- CPW issued a voluntary noon-to-midnight fishing closure on this exact reach, from the Highway 160/84 bridge to Yamaguchi Park, during a 2026 heat event (CPW news, Jul 13, 2026).
- From the Highway 160/84 bridge to Apache Street (including the River Center Ponds), regulations set a 2-trout limit; the reach is not Gold Medal water (CPW 2024 fishing brochure).
Getting to the San Juan River
The named in-town access points come from the Pagosa Springs tourism office's fishing brochure rather than a municipal parks page.
- Downtown access behind the River Center, Town Park, the Visitor Center, and Yamaguchi Park -- regularly stocked water, good for kids/beginners (Visit Pagosa Springs). Town parks are open dawn to dusk (Visit Pagosa Springs).
- East Fork and West Fork of the San Juan, both a short drive up Hwy 160 -- bank/road access with nearby campgrounds; portions of the West Fork cross private property (Visit Pagosa Springs).
- US 160/84 junction downstream through Pagosa Springs to Apache Street (covers the tracked stretch): trout bag/possession limit of 2 (CPW special regulations). In July 2026, CPW asked anglers not to fish after noon on the downtown San Juan stretch as water temperatures approached 71°F (Pagosa Daily Post).
