Yakima/Huntsville Screen Evaluation

This project is being conducted at up to 26 Phase II fish screening facilities in the Yakima River basin and 1 on the Touchet River, all in Washington.

Work to Be Performed

The approach to evaluating Phase II screens includes three tasks; on-site evaluation of operating screens; implementation of a protocol for problem identification, correction, and follow-up, and communication of the findings.

Task I-A, Field Evaluations - During 2006, we will examine up to 26 fish screening facilities in the Yakima River Basin and Touchet River and evaluate their operation using the 3-step approach (Table 1). We will determine if sites are properly equipped to provide safe, efficient fish bypass by reviewing design drawings, operating procedures, and components installed and in use at the facility. We will monitor approach and sweep velocities in front of the screens and in the fish bypass to determine if the facilities meet fish passage criteria. Screen integrity will be monitored by completing "real-time" inspections of sites using underwater video technology. The second and third evaluations may include a reduced number of sites, with emphasis being placed on those that showed some indication of problems during the initial round of evaluations, or that have shown problems later in the season in previous years. Evaluation results will be documented in the annual report that will be placed on electronic networks linked to BPA and PNNL homepages (https://www.bpa.gov/ and https://www.pnnl.gov/ecology/Projects/Screen/Reports.htm, respectively).

Task I-B, Problem identification protocol task - We will continue to implement a standardized protocol for identifying, correcting, and following up any problems that may be discovered during our evaluations. As in the past, problems identified in the field will be reported to the Washington Department of Fish and Wildlife (WDFW) or U.S. Bureau of Reclamation (BOR) screen shop immediately via phone with email confirmation. In addition, problems identified in the office during review of the underwater video tapes and velocity data will be reported to the appropriate O&M staff. We will document problems on a problem-tracking form. We will revisit the site within one to two weeks of being notified that changes have been made to correct the problem to confirm the effictiveness of the changes. Timing of the follow-up evaluation will depend on the time of year, with more rapid follow-ups occurring when anadromous smolts are emigrating. If O&M staff have not responded within one week, a repeat notification will be issued. Response times and effectiveness of repairs/modifications will be included as a separate section in the annual reports. Open lines of communication among cooperating agencies will result in a more rapid response to correct failures or deficiencies.

Task 1-C, Communication of Screens Evaluation information - Evaluation results will be documented in the annual report that will be placed on electronic networks linked to BPA and PNNL homepages (https://www.bpa.gov/ and https://www.pnnl.gov/ecology/Projects/Screen/Reports.htm, respectively). Information collected during the evaluation of fish screens in the Yakima Basin is of interest to fisheries and habitat managers within and outside of the Yakima River Basin. One PNNL staff member may attend meetings or workshops to present pertinent information obtained through the performance of this contract.
