P-17 Water Conservation Project
Custer County, Idaho 

PROJECT DESCRIPTION:
The U.S. Bureau of Land Management (BLM), in partnership with the Custer Soil and Water Conservation District, the Idaho Department of Fish and Game, and the Bonneville Power Administration (BPA), is proposing a water conservation and fish habitat enhancement project on the Pahsimeroi River in Custer County, Oregon.  The project would be located on lands managed by the BLM and BPA is proposing to fund the project.
The project would help remove an anadromous fish passage barrier (at the P-17 irrigation water diversion), eliminate conditions that entrain and kill fish in irrigation ditches, and increase summer flows in the Pahsimeroi River by increasing irrigation efficiencies. 

The project would involve replacing the existing P-17 water diversion with a diversion that supports fish passage and installing the following structures: a new headgate structure, 300 feet of ditch,  a fish screen (to be installed about 500 feet downstream of the headgate to prevent fish from continuing down the ditch); a bypass pipe (that would return fish safely to the Pahsimeroi River); and about 3,500 feet of buried pipeline (to convey the fish-screened irrigation water across BLM administered lands to private land for irrigation use).  The river bank at the new diversion site would be reshaped and planted to restore riparian conditions.


ENVIRONMENTAL REVIEW PROCESS:
To understand the potential environmental impacts of this proposal, the BLM is developing an environmental assessment (EA) following the procedures of the National Environmental Policy Act.  BPA is a cooperating agency in the development of the EA.  The EA will describe anticipated impacts on natural and human resources, as well as mitigation measures to help avoid or minimize impacts. Below is the environmental review schedule:

​Scoping comment period
Draft EA comment period
Final EA
Finding of No Significant Impact (if warranted)
If decision to build, construction start
March 16, 2017 - April 17, 2017
none
June 2018
June 2018
Summer and fall 2018​
 
CURRENT STATUS:
BLM conducted public scoping in March and April, 2017 and is now working with BPA in preparing a draft EA for release in June 2018.
