Ground-water-levels-spring85.pdf |
USGS | 1989 | Groundwater level contour maps for three basalt units of the Columbia Plateau regional aquifer system were constructed by using water levels measured in 1,105 wells during 1985. These measurements then were compared with similar measurements from spring 1983 to assess the changes in groundwater levels over the 2-year period for each of the basalt units.

Walla Walla Basin Watershed Council | 2010 | One of the greatest barriers to salmonid survival in the Walla Walla Basin is thermal water quality. The 2002/2003 Total Maximum Daily Load (TMDL) temperature studies carried out on the three major basin riversfound that water temperatureoften reachedlethal levelsfor salmonid species. The Oregon TMDLassessment conducted by the Oregon Department of Environmental Quality (ODEQ) and the Walla Walla Basin Watershed. Council (WWBWC)in 2000 found that seven-day moving average temperatures on the main stem Walla Walla River exceeded the Oregon state water quality standard1on 36 of the 43 study sites on the Walla Walla River (Butcher et. al, 2005). The standard was also exceeded at all sevenstudy sites on the Touchet River and Mill Creek (Butcher et. al, 2005). The ODEQ/WWBWC TMDL assessment citedincreased in-stream flows and increased shade as the most critical factors for lowering the currently high water temperatures to meet thermal water quality standards. | Consultant reports - Agency reviewed/approved | Walla Walla Basin, TMDL, Total Maximum Daily Loads, instream flows, Touchet River, Mill Creek, Walla Walla Watershed, fisheries, riparian vegetation, riparian habitat, land use |

HDR EES, Inc. | 2007 | The Walla Walla River Basin is an important aquatic resource that empties into the Columbia River downstream of the Snake River confluence and upstream of McNary Dam at approximately River Mile 315 (RKm 507). As illustrated in Figure 1, the main stem of the Walla Walla River originates in the Blue Mountains of eastern Oregon before crossing the state line into Washington near the towns of Milton-Freewater, Oregon and Walla Walla, Washington. Because of increasing concerns for resident bull trout and anadromous salmonid species in the basin, fish and water management agencies have begun to examine steps needed to protect several important rearing and spawning reaches in the river system. One issue concerns the impact of water temperatures in the main stem of the Walla Walla River. | Consultant reports - Agency reviewed/approved | Walla Walla River Basin, Columbia River, goundwater, instream, flow calibration, North Fork, South Fork, Little Walla Walla, Touchet River, fisheries, streamflow, water quality |

Courtney van Stolk | 2019 | This study collected a significant amount of data on groundwater isotopic and chemical composition in the Walla Walla Subbasin that could provide input for future research to better understand its groundwater system. In particular, a partial mixing model using carbon-14 and tritium concentrations would allow for estimates of recharge volumes along different flow paths and timescales in the subbasin. One statistical weakness of this study was the small number of wells with the full suite of chemical and isotopic parameters used in the principal component analyses. This issue could be solved by including more data points from wells that are being sampled as part of a planned USGS and Washington Department of Ecology study in the Washington portion of the Walla Walla River Basin that will take place in 2019 and 2020. | Peer reviewed | Walla Walla Basin, Oregon, Oregon State University, Walla Walla Subbasin, USGS, WA Depy.

Assessing Success of the Walla Walla Watershed Management Partnership Pilot - Perfomance Audit PerformanceAudit.pdf |
Office of the Washington State Auditor | 2020 | Codified in 2009 (RCW 90.92), the Walla Walla Watershed Management Partnership was originally a 10-year pilot allowing water management through a locally focused, collaborative approach without the Department of Ecology's usual regulatory oversight. Although the Legislature created the water management pilot to improve streamflow, the board's initial strategic plan only cited it in connection with establishing local water plans. In its 2018 report to the Legislature, the Partnership acknowledged streamflow did not improve, but thought the pilot succeeded in bringing diverse interests to the table. Our statistical analysis also suggests that streamflow did not change, and similar statistical models could be used to help evaluate future efforts. | Federal/State/Tribal/Local agency | Walla Walla watershed, water management, instream flows, endangered fish, water demand, water banking, water plans, well mitigation, audit, funding, WWWMP |

Shoreline Restoration Plan City of Dayton, Washington Shoreline Master Program Update Ord_1882SRP.pdf |
URS | 2015 | Under the Washington State Shoreline Management Act (SMA), each city and county with "shorelines of the state" must adopt a Shoreline Master Program (SMP) based on state laws and rules but tailored to the specific geographic, economic, and environmental needs of the community. The primary goal that must be addressed in an SMP update is how to achieve "no net loss of ecological shoreline functions necessary to sustain shoreline natural resources" (Ecology 2004).

This Technical Memorandum explores the viability by describing the generaldifferences between the two reservoir sites and providing a comparison with the other alternatives from the 2019 Flow Study. The comparison is provided by adding the LPCR as Alternative 5 in the summary figures and tables from Section 4, Performance and Cost, of the 2019 Flow Study. The details about the figures and tables are not duplicated herein but can be readily referenced in the 2019 Flow Study. Drawings depicting the associated facilities of the LPCR are provided in Attachment 1. | Consultant reports - Agency reviewed/approved | Walla Walla Basin Watershed Partnership, Flow Study, Walla Walla River, fish, wildlife, stream flow, funding, cost, Office of Columbia River, booster pumps, Walla Walla Basin, Lower Pine Creek, pump station, pipeline, dam, reservoir, funding models, O&M, Reclamation, Oregon, Umatilla, Columbia River, drought relief, groundwater, Grand Coulee Dam, instream flow, Odessa, grants, taxes, cost reduction, RCW, pumping facilities |
Addendum to the Flow Study 2019 Update Report WWFS_Addendum_201_FlowStudy.pdf |
Jacobs Engineering Group and Aspect Consulting | 2021 | This memo documents the current status of the Walla Walla River Bi-State Flow Study (Flow Study) completed in June 2021 as an addendum to the 2019 Flow Study Update (December 2019) report. This 2020-2021 biennium phase of the Flow Study builds upon over a decade of work by multiple basin stakeholders documented in the Walla Walla Basin Integrated Flow Enhancement Study (November 2017), and the Flow Study Update (December 2019). The previous reports identified the Flow Study geographical context, objectives, stakeholders, and documented the process where over 100 water supply projects were evaluated and focused to four specific water supply alternatives to improve flows in the mainstem Walla Walla River. The current phase of the project seeks to further refine the four previously selected alternatives plus one new alternative that emerged during this phase with the goal of focusing on a preferred water supply alternative. | Consultant reports - Agency reviewed/approved | Walla Walla Basin Watershed Partnership, Flow Study, Walla Walla River, fish, wildlife, stream flow, funding, cost, Office of Columbia River, booster pumps, Walla Walla Basin, Lower Pine Creek, pump station, pipeline, dam, reservoir, funding models, O&M, Reclamation, Oregon, Umatilla, Columbia River, drought relief, groundwater, Grand Coulee Dam, instream flow, Odessa, grants, taxes, cost reduction, RCW, pumping facilities |

Critical Low Flow Plan For the Walla Walla Basin CLFP_Plan_ Apr_2015_FINAL.pdf |
Walla Walla Watershed Management Partnership | 2015 | Critical Low Flow Plan to develop Walla Walla River drought response. The purpose of this plan is to prevent take of ESA listed species and Spring Chinook due to critical low flows. This drought response strategy was developed by basin partners, fisheries co-managers, and water users. Initiation and implementation of the Critical Low Flow Plan would require a Critical Low Flow Declaration made by CTUIR, ODFW, and WDFW, and this initiation can be made in conjuction with or independent of a drought declaration from state government. | Miscellaneous non-peer reviewed | Critical Low Flow Plan, Walla Walla Basin, Drought, Declaration, Endangered Species Act, ESA, fisheries, Spring Chinook, pulse flows, snowpack, source switch, surface water, groundwater, trap and haul, Walla Walla River, Mill Creek, Yellowhawk Creek, Touchet River |
