ERTA West: Fish Passage Barrier and Diversion Screening Inventories ERTA West staff conduct state-wide inventories of fish passage barriers and unscreened surface water diversions. Fish passage features evaluated include culverts, fishways, tide gates, dams and other human-made, instream structures. Gravity diversions and pumps are also inventoried. ERTA West has completed comprehensive fish passage inventories at WDFW’s Hatcheries and at Thurston County and Jefferson County road crossings. ERTA West also inventoried parts of Kitsap, Skagit and Whatcom counties, while conducting habitat assessment. Presently, ERTA West is inventorying Washington State Department of Transportation (WSDOT) highways and WDFW owned and managed lands for fish passage and screening features. ERTA West supports other agencies, citizens and non-profit groups in conducting fish passage inventories in their jurisdictional areas and local watersheds by providing free training and technical assistance. The data are entered into the WDFW Fish Passage and Diversion Screening Inventory (FPDSI) Database. The FPDSI is the repository for data associated with fish passage barrier and diversion screening inventories. It is intended to provide a common framework for collection, storage, retrieval, and dissemination of information pertaining to the location and fish passage barrier status of culverts, dams, fishways, and other human-made structures. The FPDSI includes data compiled from several WDFW inventory efforts as well as data from a variety of non-WDFW inventory efforts. The data are statewide in scope but do not represent a comprehensive or complete inventory of fish passage features. For example it is estimated the FPDSI currently contains information on only 15 - 20% of the potential culvert crossings existent within the state. To date, more than 18,000 culvert crossings have been identified and assessed within Washington's waterways. As inventory efforts continue these numbers will increase. Data stored in the FPDSI database is maintained for agency and public use. Data from the FPDSI is incorporated into the Salmon and Steelhead Habitat Inventory and Assessment Program (SSHIAP) data layers and the Salmonscape Internet map application. To request FPDSI data, or for more information, contact Brian Benson at (360) 902-2570, bensoblb@dfw.wa.gov. In 1998, WDFW published the Fish Passage Barrier and Surface Water Diversion Screening Assessment and Prioritization Manual. Last updated in August 2000, TAPPS is currently updating the manual for 2006. This manual describes fish passage barrier, diversion screening and habitat assessment protocols WDFW uses and recommends to other entities for inventory efforts. The manual is intended to provide a consistent methodology for fish passage barrier assessment and prioritization. This method is the foundation for the data contained in the FPDSI database. WDFW/TAPPS uses information collected during the inventories to identify opportunities for fish passage, screening and habitat restoration. Once identified, TAPPS staff further scope and prioritize projects, develop preliminary designs and request funding for projects to be completed on WDFW owned or managed land. ERTA biologists then work with WDFW Business Services Program engineers, engineering aides and construction crews to further develop and construct fish passage, screening and habitat projects.
