From The Colorado Springs Gazette (Rachel Riley):

The $9 million project will replace an intake and diversion structure and install a fish passage and boat chute on what is considered the last non-navigable stretch of the river between Leadville and Cañon City, according to a Thursday news release from the local utility provider.

Once the project is completed, skilled whitewater boaters, including rafters and kayakers, will be able to traverse the span of river near Clear Creek Reservoir without portaging…

Aurora Water, [Colorado Springs Utilities] is also financing construction on the project, and grants from Colorado Parks and Wildlife and the Colorado Water Conservation Board are providing about $1.2 million.

The stone diversion, south of Granite, was constructed in 1964 as the original intake for the Otero Pump Station a few miles north of Buena Vista. At the time, river recreation was not considered during the design process, said Brian McCormick, a senior project engineer for Colorado Springs Utilities.

“This project will bring this diversion and this site up to modern design standards, including the addition of facilities for recreational boating,” McCormick said.

“This is a real nice example of really balancing both the demands we place on the river for water supply and for recreation.”

The structure is now a backup intake for the pump station, which is served by water from nearby Twin Lakes, he said. It is part of the Homestake Project, a partnership between Aurora Water and Colorado Springs Utilities to move water from west of the Continental Divide eastward to the two Front Range cities.

The project, slated for completion in November 2019, will affect about 400 feet of the river. Construction in the river is expected to begin after Labor Day weekend, McCormick said.

The fish passage, also known as a fish ladder, will allow brown and rainbow trout to swim upstream past the diversion when they spawn, he said.

The boat chute will be a channel on one side of the river made up of a series of drops and pools to get the boats safely past the structure, McCormick said.

Commercial outfitters raft the stretch now, but they must portage to get around the diversion, with its jagged concrete and exposed steel, said Rob White, park manager of the Arkansas Headwaters Recreation Area.

The project will add “a nice stretch of whitewater possibilities” for adventure-seekers ready for rapids ranked Class III and above, White said.

Utilities and Aurora Water staff members have spent more than a decade developing the project. The Pueblo Board of Water Works is donating easements needed to build and maintain the diversion, according to the news release.

The AHRA Clear Creek North Recreation Site will be closed during the project, but the Clear Creek South Recreation Site will remain open, the release says.
