Section 1. Summary

Title of project
Upper Salmon River Diversion Consolidation Program

BPA project number   9600700

Short description
Consolidate diversions at four (4) upper Salmon River sites (S-14, S-13, S-12, S-11), pump 15 cfs Salmon River water into L-6 canal during periods of Lemhi River low flow for salmon passage and construct a new fish screen at S-28 to accommodate the additional flow from the S-26, S-29, Chester pump consolidation (in progress FY97).

Section 3. Background

Stream area affected

Stream name   Salmon
Stream miles affected   All
Hydro project   N/A. This project does not mitigate for a specific hydroelectric project.
Subbasin   Salmon
Land ownership   Private
Habitat types   N/A. This project deals with fish passage issues, not fish habitat.

History
The first phase of the project (S-32 diversion consolidation) is complete. S-28 consolidation (Phase II) is underway. S-14 consolidation and S-28 fish screen construction (Phase III) will start late fall of 1997. The Bureau of Reclamation has provided canal surveys, archaeological surveys, NEPA, and structure designs for Phase I & II and will provide the same for Phase III work.

Biological results achieved
The diversion consolidation at S-32 is complete and resulted in three (3) gravity diversions eliminated from the Salmon River near Challis, Id. Several irrigators provided cost sharing and converted to sprinkler irrigation which results in less water being diverted from the Salmon River. Three fish screens were eliminated as well as three "push-up" gravel berms.

Adaptive management implications
The successful completion of the S-32 consolidation project improved the "trust" level of many local ranchers in working on current and future projects with the many state, federal, and tribal people involved.

Section 4. Purpose and methods

Specific measureable objectives
Phase III project (FY98) will consolidate four (4) gravity diversions into a single diversion near Salmon, Id. Additionally, Salmon River water (up to 15 cfs) will be pumped into the L-6 canal during periods of low flow in the Lemhi River to provide for salmon passage as needed. A new fish screen will be constructed on the S-28 canal near Challis, Id. S-28 consolidation project currently underway.

Critical uncertainties
None

Biological need
Irrigation diversions can be detrimental to migrating fish in several ways. Juvenile fish can be diverted into the irrigation canal causing migration delays or usually death. Gravel berms constructed in the river to divert water can act as passage impediments to adult fish and may result in dewatering downstream sections. Operation of heavy equipment to construct the gravel berms causes streambed disturbance releasing sediment into the stream. In addition, any time equipment is operated in a stream there is a risk of spills of petroleum or other toxic substances. Pumping up to 15 cfs of Salmon River water into the L-6 canal will therefore allow 15 cfs to remain "instream" in the often totally dewatered lower portion of the Lemhi River for salmon passage as needed.

Hypothesis to be tested
None

Alternative approaches
N/A. There are no acceptable alternatives.

Justification for planning
N/A. This project is an implementation project.

Methods
The canals of the diversions to be retained (S-14 and S-28) will need to be enlarged to accomodate water from the eliminated diversions. Delivery systems to transport water from the retained diversion canal to the new irrigators will be built. The newly enlarged canals (including S-32) will also need new fish screens to accomodate additional amounts of water. Financial assistance in purchasing on-farm sprinkler systems will be provided. Long term O&M will be the responsibility of the project recipient (IDF&G & irrigators) with the exception of the Salmon River pump plant.

Section 6. Outcomes, monitoring and evaluation

SUMMARY OF EXPECTED OUTCOMES

Expected performance of target population or quality change in land area affected
Several benefits are gained by implementation of the project. Immediate benefits for fish include reducing points of diversion that entrain juveniles in irrigation canals, eliminating gravel berms which act as passage impediments to adults, and increasing instream flows (through conversion from flood to sprinkler irrigation). Several of the fish screens on the diversions do not currently meet the latest National Marine Fisheries Service criteria. By eliminating diversions, fish screen construction, operation, and maintenance costs will be substantially reduced. The affected irrigators will realize reduced canal maintenance costs, reduced time and money to construct gravel berms, and, for those irrigators converting to sprinkler, improved crop production.

Contribution toward long-term goal
Increase survival of both juvenile and adult anadromous fish by providing better fish passageconditions and increased instream flow.

Physical products
Canal enlargement, fish screens, bifurcation structures, head gate and pump station.

Environmental attributes affected by the project
Improved passage conditions for both juveniles and adult plus improved instream flows are the major benefits of the ongoing project.

NR

MONITORING APPROACH
The canals of the diversions to be retained (S-14 and S-28) will need to be enlarged to accomodate water from the eliminated diversions. Delivery systems to transport water from the retained diversion canal to the new irrigators will be built. The newly enlarged canals (including S-32) will also need new fish screens to accomodate additional amounts of water. Financial assistance in purchasing on-farm sprinkler systems will be provided.
