Wenatchee Basin Barrier & Diversion Assessment

In 2016 CCFEG began a fish passage barrier assessment of the entire Wenatchee River Watershed. Barriers to adult and/or juvenile fish migration exist throughout the basin and result from undersized culverts, poorly designed irrigation diversions, dams, and debris jams. The information gathered through this project will be used to objectively prioritize the correction of these barriers in the future.


The Wenatchee River watershed is home to three species of fish listed under the Endangered Species Act (Spring Chinook, Steelhead, and Bull Trout) as well as numerous other native fish species. By prioritizing and eventually correcting fish migration barriers we can increase the amount of stream available for spawning adults as well as growing juveniles, with the ultimate goal of increasing populations.The historic range of many fish species has been drastically reduced by these passage barriers, and this disconnected habitat is critical to their recovery. CCFEG regularly works with private landowners to remove barriers at no cost to the landowner. Landowners un-interested in removing barriers will not be required or asked to take further action.

Specific watersheds that will be assessed include:

  • Nason Creek
  • Peshastin Creek
  • Chiwawa River
  • Icicle River
  • White River
  • Little Wenatchee River
  • Chumstick Creek
  • Chiwaukum Creek
  • And other tributaries to the Wenatchee River


This project is being done in conjunction with the Washington Department of Fish and Wildlife. For more information on statewide efforts to identify and correct barriers to fish migration click here http://wdfw.wa.gov/conservation/habitat/fish_passage/
