About Colorado River Fishing
The upper Colorado River near Kremmling and Hot Sulphur Springs offers excellent fly fishing in a stunning mountain setting with far less pressure than Colorado's more famous tailwaters.

Best Time to Fish Colorado River
Summer months bring reliable PMD and caddis hatches that drive consistent dry fly action throughout the season. Spring runoff subsides by early June, creating optimal conditions that last through September when cooler temperatures signal the transition to fall.
Species
Brown trout dominate the Colorado River here, offering selective feeding opportunities and strong hook-to-hand ratios for skilled anglers. Rainbow trout are also present throughout the system, typically running smaller but providing excellent action during heavy hatch periods.
Access & Regulations
Always check the current Colorado fishing regulations before heading out. Regulations on Colorado River may include special catch-and-release sections, artificial-only stretches, and seasonal closures. A valid Colorado fishing license is required.
Live River Data
Live flow and gauge readings are sourced from the USGS National Water Information System and updated every 15–60 minutes. CFS (cubic feet per second) and gauge height give you a current snapshot of river conditions before your trip.
