Weekly River Report
September 3, 2026 -
Summary:
Rivers in the Roaring Fork Watershed are flowing 23-47% of normal for this time of year. Monsoon patterns produced rainfall over the last week, providing moisture for thirsty soils and vegetation, and cooler air temperatures. Local precipitation gauges recorded moderate totals, with the largest accumulation at McClure Pass (0.8”), Emma (0.8”), and Redstone (1.3”). Despite this rainfall, the Roaring Fork River in Aspen and Emma, the Fryingpan River at Thomasville, and Colorado River in Glenwood Springs are all experiencing record-breaking low flows. We will need much more rain to improve drought conditions and decrease wildfire danger. Releases from Ruedi Reservoir dropped 393 cfs in the last week and the lower Fryingpan River is currently flowing 69 cfs. Ruedi releases were elevated in August due to entities with storage rights in the reservoir calling for contracted water. With those shares exhausted, releases have returned to this lower rate.


Calling All River Users to Protect Waterways from New Threats
It is time for every water user to take seriously their role in being a river steward. After you fish, boat, kayak, or stand-up paddleboard CLEAN, DRAIN, and DRY all your gear. Every time. Yes, really, every time.
