Upper Colorado Recovery
Northern Water is a participant in the Upper Colorado River Endangered Fish Recovery Program.
The program’s purpose is to re-establish populations of threatened and endangered species in the Upper Colorado River basin.
The effort began in 1988 when a coalition of federal, state and regional agencies agreed to recover the endangered fish while simultaneously preserving future water development opportunities. Northern Water chose to voluntarily participate in the recovery program.
Four Endangered Fish The effort focuses on four endangered species in the Upper Colorado River:
- Colorado pikeminnow
- Razorback sucker
- Humpback chub
Once abundant in the Colorado River and many of its tributaries, these fish now exist in much smaller numbers in only a few places in the basin.
Protecting Fish in the 15-Mile Reach
A principal program component includes providing additional water for aquatic life in the 15-Mile Reach of the Colorado River, located immediately above the confluence of the Colorado and Gunnison rivers at Grand Junction.
As a part of the program, Upper Colorado River water users agreed to supply 10,825 acre feet of water annually to the Colorado River in late summer for the endangered fish. Colorado River water users have been contributing this water annually since 2000.
10,825 Acre Feet of Water
The Denver Water Department agreed to provide an interim source for the 10,825 acre feet of water out of Williams Fork Reservoir. Colorado River water users are in the process of implementing a permanent source of this water.
Recovery program participants have established these strategies and goals:
- Enhance spring river flows by releasing water without adversely affecting project yields.
- Supplement river flows in late summer for young fish.
- Manage stocking and non-native fish management programs to enhance endangered fish recovery work.
- Construct passageways and ladders around specified dams and barriers to allow fish migration.
- Raise endangered fish in hatcheries for stocking.
- Coordinate and conduct additional research on endangered fish.
- Improve aquatic habitat.
