Title of project
Yakima Phase II Screens - Construction
BPA project number 9107500
Install new fish screens at all significant diversions in the Yakima River Basin to keep juvenile salmon and steelhead from being diverted and lost in the canals during outmigration. Improve adult upstream passage at selected sites.
Business name of agency, institution or organization requesting funding
US Bureau of Reclamation

Supports a healthy Columbia basin; increases run sizes or populations

Planning Report completed in FY1990. Preliminary & final design initiated in FY1990-91. First construction initiated in FY1992. As of FY1997, construction of screens, consolidation of ditches, elimination of diversions or other corrective measures are complete on about 1/2 (30+) of the Phase II diversions. About 1/4 of the sites have been eliminated due to non-use or have been screened by the Washington Department of Fish and Wildlife using small prefabricated modular screen units. Data collection, preliminary & final design is underway on the remaining 15 sites. Uncertainties in the consolidation process continue to delay construction of some new screens until final consolidation plans are made and funding is secured . Water rights ajudication will delay construction at some sights because of uncertainties in selecting appropriate design flows. Difficulties in securing rights-of-way at some sites (particularly sites on the YIN reservation) has delayed and may continue to delay construction at some sites.
Biological results achieved
Testing of completed screens using live fish indicates excellent performance that results in no significant losses or injury to juveniles. Delays in downstream migration are significantly reduced as juveniles are bypassed quickly through the screening facilities back to the river.
Project reports and papers
Conceptual plans are documented with Predesign Memoranda that serve as the basis for final design. Technical Work Group meeting dicsussions and decisions are documented in the minutes of the meetings. Biological evaluation and testing of completed screens has been documented at all Phase I sites and will continue at selected Phase II sites.
Adaptive management implications
Knowledge gained from observation, operation, and testing of completed facilities is used to refine and change design criteria and design details of new facilities.
Specific measureable objectives
All Phase II diversion sites will be screened to meet current agency design criteria for effective fish protection and fish passage by the year 2001. The target objectives of adequate juvenile fish passage are designed to meet three criteria which will: (1) reduce delay to a degree approaching zero; (2) reduce the possibility of injury to a degree approaching zero; and (3) allow fish to pass with little additional expenditure of energy.
Old screens do not meet current agency criteria for effective fish passage. As a result, many salmon and steelhead fry and smolts are injured at these facilities or are entrained into the irrigation canals and lost. These losses have been documented in studies of selected Naches and Yakima River screens and have been observed at various sites in the basin.
Hypothesis to be tested
Justification for planning
|Phase Planning||Start 1990||End 2000||Subcontractor No|
|Major tasks in FY1997 include initiation and continuation of predesign work at about 15 screen sites and preparation of final designs and specifications at about 5 screen sites. Major tasks in FY1998 include completion of predesign work at about 8 screen sites and preparation of final designs and specifications at about 5 screen sites. Major tasks in FY1999 include completion of predesign work at about 5 screen sites and preparation of final designs and specifications at about 5 screen sites. Major tasks in FY2000 include completion of predesign work at about 5 screen sites and preparation of final designs and specifications at about 5 screen sites.|
|Phase Implementation||Start 1992||End 2001||Subcontractor No|
|Major tasks in FY1997 include completion of construction at 8 sites and initiation of construction at 5 additional sites. Major tasks in FY1998 include completion of construction at 5 sites and initiation of construction at 5 additional sites. Major tasks in FY1999 include completion of construction at 5 sites and initiation of modifications at 5 additional sites. Major tasks in FY2000 include completion of construction at 5 sites and initiation of modifications at selected sites.|
|Phase O&M||Start 1992||End Ongoing||Subcontractor No|
|Operate and maintain fish screens|
Constraints or factors that may cause schedule or budget changes
Uncertainties in the consolidation process continue to delay construction of some new screens until final consolidation plans are made and funding is secured . Water rights ajudication will delay construction at some sights because of uncertainties in selecting appropriate design flows. Difficulties in securing rights-of-way at some sites (particularly sites on the YIN reservation) has delayed and may continue to delay construction at some sites.
SUMMARY OF EXPECTED OUTCOMES
Expected performance of target population or quality change in land area affected
Precise numerical estimates of fishery improvements attributable to the screening program are difficult to assess because of the lack of historical data and the many variables involved. The potential increases in returning adults with adequate fish passage and protective facilities installed at Phase I and II sites and with adequate instream flows, improved habitat conditions, and a hatchery is estimated at about 85,000 fish, of which half may escape and return to spawn.
About 60 Phase II diversions will be equipped with state of the art fish screens that meet current agency criteria.
Predesign Memoranda summarize existing site conditions and outline proposed improvements and alternatives.
Provisions to monitor population status or habitat quality
Juvenile evaluation facilities are operational at Roza and Prosser diversion dams. All Phase I and Phase II fish screens can be retrofitted to monitor juveniles as needed. Adults can be collected and evaluated at Roza, Prosser , and Horn Rapids diversion dams and can be monitored at Naches-Cowiche diversion dam.
Increasing public awareness of F&W activities
Some of the Phase II fish screens are highly visible and are located in areas that are used heavily by the public. For example, Congdon screen is located inside the popular Yakima County Eschbach Park. At this particular site, we provided an interpretive sign and viewing area at the new screen site. The old screens were removed and set up at a historical museum in Union Gap.

Opportunities for cooperation
Consolidation proposals at several diversions offer opportunities for significant fish screen cost savings.

How does percentage apply to direct costs
Overhead percentage applies only to about 1/3 of project direct costs.
