Habitat work to improve ark below Leadville, Colorado

LEADVILLE, Colo. – Fish habitat enhancement work is set to begin later this year on public parts of the upper Arkansas River below the Highway 24 bridge as biologists and engineers with Colorado Parks and Wildlife prepare to restore a  section of river that was once mostly lifeless because of decades of mining activity.

The river restoration work is a key part of the federal and state effort to restore the California Gulch Superfund Site, an 18-square mile area where historic mining activities occurred. Mines in the area created the discharge of heavy metals and acid into California Gulch at the headwaters of the Arkansas River, making the river in that area unable to sustain healthy fish populations. The river currently supports a good trout population because of earlier mine cleanup efforts and will be further enhanced by the upcoming habitat improvements.

"The planning for this project has been going on for many years and people in the area are excited to see it moving forward," said Greg Policky, aquatic biologist for Colorado Parks and Wildlife in the area. "By this summer we hope to be in the river and physically manipulating the habitat to restore the environment for aquatic life in that section. Over the next few years, we hope anglers will start to see the benefits."

Improvements will be centered on an 11-mile stretch of the river from California Gulch downstream to Twobit Gulch. Public river access in the area includes the Arkansas Headwaters Recreation Area, which is managed by Colorado Parks and Wildlife, and numerous fishing access easements held by the agency.

While this project is on public lands, there are separate projects on the privately held sections of the river, including two large publicly-accessible ranches owned by Aurora Water. The Hallenbeck Ranch and part of the Hayden Ranch are owned by Aurora Water and are private lands though there is some public fishing access. Public access to the Hallenbeck Ranch parcel ended this year but Aurora officials are opening the river sections of the Hayden Ranch for public access on May 1. 

"These habitat improvements will provide immense benefits to the fishery and the anglers who frequent this part of the Arkansas Headwaters Recreation Area," noted Rob White, Park Manager for the Arkansas Headwaters. "We are very fortunate to have received funding for this work."

The restoration work will utilize heavy machinery to move rocks, logs and other materials in and out of the river channel to improve fish habitat. As a result, downstream anglers may see periods of muddy water and other evidence of disturbance during the project.  

"Anglers might deal with a short-term disturbance, but in the long run this work should have a big positive upside," said Tracy Kittell, Colorado Parks and Wildlife engineer. "For public safety, we'll mark the areas where work is occurring and require that anglers bypass those areas."

The in-stream and riparian habitat restoration projects are only one part of the overall river restoration effort on the upper Arkansas. Other elements include water-quality monitoring, upland habitat improvements, habitat protection efforts and noxious weed control.

Colorado Parks and Wildlife is pleased to be a partner in the river restoration project with the U.S. Fish and Wildlife Service, Environmental Protection Agency, Bureau of Land Management, Bureau of Reclamation and the Colorado Department of Public Health and Environment.

Colorado Parks and Wildlife was created by the merger of Colorado State Parks and the Colorado Division of Wildlife, two nationally recognized leaders in conservation, outdoor recreation and wildlife management. Colorado Parks and Wildlife manages 42 state parks, all of Colorado's wildlife, more than 300 state wildlife areas and a host of recreational programs.
