Boulder Fly Casters Work to Restore Boulder Creek

Trout Unlimited chapters throughout Colorado are dedicated to working on the conservation of habitat in their area. Boulder Fly Casters has been working tirelessly with several conservation projects, including one to restore the Upper South Boulder Creek. At two areas, Boulder Fly Casters are helping restore the creek at two separate areas: the Moffat Tunnel and the Jumbo Mountain Picnic Area. At both of these areas, at times of low flow, <10 CFS to >1000 CFS (Cubic Feet per Second), fish passages were blocked and the river offered very few holding areas.

According to Tim D’Avis, project supervisor and Boulder Fly Casters Board of Directors member, “The original stream wandered through the valley in the Moffat Tunnel area.  With the advent of the water tunnel and railroad tunnel, the stream channel was routed next to the mountains on the south side of the valley.  In the Jumbo Mountain area, the stream was pinched between the road and the railroad.”

In the spring of 2013, the restoration projects began. Efforts were soon made to build more bends in the stream to allow for more water flow. Along with more added structure, these bends will, according to D’Avis, address “the need to get water efficiently to Gross Reservoir.” The images below show the restoration sites and what is being done at each of those sites.

The Fishing is Fun Grant for $80,000 along with the Denver Water Board providing $124,900 made the restoration efforts possible. The United States Forest Service also donated roughly $10,000 worth of seeds which were scattered along the river banks. Along with the seeds planted, 700 willows were staked as well.

As of July 2014, restoration is about 95% complete according to the Boulder Fly Casting website.

Boulder Fly Casters is also working on several other projects including flood restoration , restoring Middle Boulder Creek at Rogers Park, and restoring part of Jenny Creek.
