A Monitor channel conditions 1/1/2005 12/31/2005 Concluded Preston Bronson (Inactive) 12/30/2005 8:36:44 AM
Description: Visually monitor channel conditions weekly. The project regularly monitors channel conditions throughout the Walla Walla River (including tributaries), Mill Creek, and the lower Touchet River looking for changes in river morphology and instream structures that may potentially affect upstream and downstream migration. Regularity of monitoring is based on the occurrence of channel changing events and inspection of instream structures at varying flow levels. Specific areas of concern are identified and reported to fisheries co-managers in order that further analysis of the situation can occur and potential solutions to address the concerns can be implemented.
B Monitor flow and temperature 1/1/2005 12/31/2005 Concluded Preston Bronson (Inactive) 12/30/2005 8:36:45 AM
Description: Monitor hydrologic conditions as relates to passage as needed. Project staff makes visual observations of flow conditions multiple times per week to relate measured flow levels to passage conditions. In Oregon, river flows and irrigation usage are reviewed for the South Fork Walla Walla River and North Fork Walla Walla River using monthly reports on usage and river flows. Flow and diversion data for Oregon is provided monthly by the Oregon Department of Water Resources (OWRD). In addition, the local irrigation districts monitor river flow in the reach from Nursery Bridge Dam to the state line and include the data in their monthly river monitoring reports. In Washington, real-time flow data is checked daily by project staff by reviewing: 1) the United States Geological Survey (USGS) website for their gauging station located on the lower mainstem Walla Walla River (RM 18), below the confluence with the Touchet River, and 2) the Washington Department of Ecology (WDOE) website for two gauging stations located at pepper bridge and beet road. Information on the WDOE website is also in the local irrigation districts' monthly river monitoring reports. Actual data from these gauging stations is then correlated to observed flow/channel conditions to assess passage concerns at varying flow levels.
C Monitor passage facility operations 1/1/2005 12/31/2005 Concluded Preston Bronson (Inactive) 12/30/2005 8:36:47 AM
Description: All BPA funded passage facilities are inspected weekly to ensure they are operating within design criteria. The major BPA facilities associated with the project are located at the Garden City/Lowden II Canal (river mile 31.0 - ladder and screen), Burlingame Canal (river mile 36.0 - ladder and screens), Nursery Bridge Dam (rivermile 46.0 - ladder), and Little Walla Walla River (rivermile 47.0 - ladder and screens). If facilities are out of criteria, adjustments are made by project staff or communicated to BPA O&M staff for correction (Jon Brough of Hudson Bay Irrigation District for Little Walla Walla River and Nursery Bridge and Stuart Durfee of Gardena Farms Irrigation District for Burlingame and Gardena/Lowden II). In addition, the project inspects Mitchell Act and private passage facilities to assess whether they are operating within criteria on a more infrequent schedule. If problems are observed, the project contacts the responsible Mitchell Act screen staff and documents in the project monthly's that are also distributed to NOAA fisheries and USFWS.
