Camp Polk Restoration Details

The restoration of Whychus Creek through Camp Polk Meadow Preserve has begun! During this multi-year restoration project, the Land Trust, in partnership with the Upper Deschutes Watershed Council and Deschutes National Forest, will work to restore the creek to its historic channel.

Learn more about the project:

• Watch a slideshow overview of the project.
• Watch videos from the restoration including the Ripples of Change documentary.
• Watch the time-lapse videos that capture the construction phase.
• Watch a recap slideshow of the construction phase (May 25-July 10, 2009).
• Watch a slideshow of aerial photos taken during the restoration.
  

Current Status: 

• Major construction of the restored channel occurred in 2009.
  
• 2010 and 2011 were growing years! More than 180,000 native plants were planted along the restored channel and then temporary fencing and irrigation was installed to help the plants grow.
  
• In October 2011, the irrigation piping and fencing was removed in preparation for the final phase of the restoration. 
• In November 2011, side channels will be constructed throughout the meadow to provide additional rearing habitat for native fish. Rocks and trees will also be stockpiled to help plug the existing channel once the water is redirected. Take a video tour of a side channel, or dig deeper on an extended restoration tour with stewardship director Amanda Egertson.
  
• In early Spring 2012: we'll "flip the switch" and redirect the water from Whychus Creek into the restored channel. This includes: finishing the excavation of the restored channel where it connects with Whychus Creek's current channel, transferring the fish from the existing channel to the restored channel, and decommissioning the existing channel by filling it with rocks, trees, and soil. Finally all roads, paths and access points from the restoration will be removed and restored.
  

Maps below show the restoration work in detail. And more information about the goals of the restoration can be found below. Be sure to join us for an on the ground restoration tour next spring, summer and fall.

Major goals of the restoration:

1. Improve habitat for redband trout, chinook and steelhead. The restored stream channel will have

• more meanders to increase overall channel length, slower water flow, and improve habitat.
• more pools will provide deep water for fish to us as refuge.
• more riffles and glides to increase habitat diversity.
• more logs to provide cover for fish and help slow flood waters.

2. Restore the wet meadow.

• improve wildlife and plant habitat by creating more wetland and streamside pland communities.
• store groundwater to help recharge the stream during low-flow periods and provide cooler water for fish during warmer months.
• increase flood-prone area so the creek can access its floodplain as it naturally would.

3. Provide for natural channel stability. The new channel will meet reference conditions for channel pattern (e.g., sinuosity,  meander length), dimension (e.g., width, depth) and profile (e.g., gradient). These reference metrics are used to develop the channel design so it closely mimics what occured prior to human disturbance.
