August Watershed Snapshot: Hot and Dry

By | UCRWG Updates, Watershed Snapshot | No Comments

Colored dots at monitoring locations reflect stream flow levels, with blue and green dots indicating water levels well above average and red and yellow dots marking water levels well below historic flows. Crosses within the dots show water temperature, while the red numbers next to selected locations show the number of days with water temperatures above 68°F/20°C from July 13th – August 13th.

The UCRWG August Snapshot looks at stream flows and water temperatures across Grand County, with a focus on the number of high water temperature days over the previous 31 day period.

Flows were low throughout much of the Upper Colorado River basin when we took our monthly snapshot on August 14th, with ongoing drought conditions and high temperatures in July and August elevating stream temperatures throughout much of the watershed and state of Colorado. Elevated flows released from Lake Granby were reflected in the Colorado River west of Kremmling, with higher water volumes keeping temperatures just below the 68°F/20°C mark for fish downstream.

Cooler waters on Muddy Creek just below Wolford Reservoir are marked by the green cross just north of Kremmling, where temperatures were within the safe zone for trout, though overall flow levels were still lower than normal.  The benefits of extra water released on the Colorado River near Pumphouse can be seen by the blue dot just southwest of Kremmling, where flows are elevated in an effort to protect endangered fish much further down the Colorado River. While the extra water lowers temperatures a bit, waters are still warm enough to stress trout.  Stream temperatures in excess of 65°F/18°C stress native trout adapted to cooler waters, while waters above 70°F/21°C result in trout having difficulties using oxygen.

Watershed Snapshot

UCRWG is excited to release our first-ever Upper Colorado River Watershed Snapshot, providing real-time modeling of stream flows in the Upper Colorado River watershed for August 1, 2018. This is a crucial first step in locally-based watershed modeling, allowing for a watershed-scale perspective on how water demands from both the Eastern and Western slopes are putting stress on the headwaters of the Upper Colorado River.

UCRWG Research: Impact Fees and Sustainable Funding Sources

By | Events, Just Ask UCRWG, Press, UCRWG Updates | No Comments

At the request of a Fraser Citizen, UCRWG recently provided research on the feasibility of using an Impact Fee to help generate sustainable, long term funding for watershed restoration projects and water and sanitation infrastructure in the Upper Colorado River headwaters.

A report by Grand Environmental Services shows that a modest fee of as little as $2.00 per month from Denver Water customers could generate as much as $7,000,000 annually for projects in the Colorado River headwaters. That much-needed cash could be available in perpetuity to help assure consistent water quality and quantity for future generations, in turn benefiting both the Eastern and Western Slopes. Read More
