Much of the Yakima and lower Naches River was diked and channelized by the Army Corps of Engineers after the 1933 flood. Impacts from diking included loss of side channel and alcove habitat by filling and channel down cutting, lost floodplain storage, increased channel velocities and loss of riparian vegetation. The project would focus on reestablishing side channel and alcove habitat, improving existing velocity cover by building deflectors and adding large woody debris, and restoring riparian habitat by planting native riparian vegetation.

Annual reports and technical papers
Specific measureable objectives
Fish utilization in reconnected side channels would be quantified.
Improving rearing habitat in this reach of the mainstem Yakima River will improve anadromous fish stock health in the basin.
Underlying assumptions or critical constraints
Fish density will be determined with mark/recapture methods.
Brief schedule of activities
The project would be initiated in year one with an engineering study of needed actions to reconnect isolated side channels. Deflectors would be constructed along channelized sections. Riparian vegetation would be planted at appropriate locations. Large woody debris would be scattered in the channel at suitable sites.
Managers believe rearing habitat for juvenile fish is severely limited in the basin. This project would redress rearing habitat function through increasing the amount of rearing habitat available.
Rearing habitat for juvenile fish is severely limited in the Yakima Basin, so much so that fish managers believe rearing habitat restoration is one of most important actions to restore stock health.
Summary of expected outcome
Rearing habitat in this reach of the river would increase. Water quality would improve over time.
Dependencies/opportunities for cooperation
Project design and implementation would be coordinated with WDFW and the county Public Works Department.
Flooding may reduce function of scattered large woody debris.
Juvenile fish density would be quantified at reconnected side channels at three times during season of use in the third year.
