Beaver Creek Dams Project

Restoring access to cold water refugia

About the Project

Beaver Creek feeds into the Wenatchee River, 46 miles upstream of the Wenatchee’s confluence with the Columbia River. The lower reaches of the creek meander through a flood plain with a healthy shrub-forest canopy, providing spawning habitat for spring Chinook and rearing habitat for multiple salmonids. The steeper upper reaches are ideal spawning and rearing habitat for bull trout and steelhead. Beaver Creek provides fish a cold-water refuge, averaging 3.7°C cooler than the Wenatchee River in August.

Several in-stream structures block full fish passage into this important habitat. Chelan County Natural Resources Department (CCNRD) removed two diversions with support from the Open River Fund.  One diversion was replaced with a fish passable system and the other with a groundwater pump. Three more barriers are being addressed in 2024, and one last barrier is being assessed. When all five barriers are removed or upgraded, fish will have access to the Creek’s full five-mile run.

FACTS AT A GLANCE
Owner: Private
Size: small, creek-spanning diversions
Project Cost: $178,000
ORF Investment: Design and permitting
Miles Opened: 3.6 miles
Fish: ESA-listed spring Chinoook, steelhead and bulltrout; also coho, rainbow, and cutthroat
Status: Completed


OUTCOMES
  • Open 3.6 miles of habitat above the barriers
  • Improve passage for ESA-endangered spring Chinook as well as ESA-threatened steelhead and bull trout. In addition, coho, rainbow trout and cutthroat trout will benefit
  • Part of a comprehensive plan to open the entire naturally accessible Beaver Creek, providing about 5 miles of habitat and access to thermal refuge
  • Reduce maintenance and operations cost for landowner
  • Support Yakama Nation treaty fishery rights
