This data release contains a dataset of continuous in-situ water temperature records from multiple federal, state, local agencies, non-profit organizations, and private industry partners across 788 locations within the Willamette River Basin (WRB) from years 2011 to 2024. This dataset complements and extends the existing multi-agency NorWeST water temperature dataset for the Willamette River Basin which includes records through 2011, by adding new sites and expanding the period of interest through 2024. This work was conducted as part of the U.S. Geological Survey (USGS) Next Generation Water Observation System (NGWOS) and Integrated Water Availability Assessments (IWAAs) projects to characterize spatial and temporal patterns in water temperature and support trends and modeling assessments by IWAAs. The data will also inform site selection in future multi-agency efforts to fill in monitoring gaps and reduce redundancy. This data release includes three files. The first (Willamette_WT_Unit_Values.csv) is a dataset of continuous water temperature data in csv format where data from multiple sources were merged into a single dataset. The second file is a zip file containing a shapefile of all locations with continuous water temperature data contained in this data release (Willamette_WT_Sites.zip). The third file (Willamette_WT_Sites.csv) contains a csv file listing the locations of each water temperature record contained in this data release.

The Quillayute River Basin in northwestern Washington consists of the Quillayute River and the river systems of its major tributaries, the Dickey, Sol Duc, and Bogachiel Rivers. With a drainage area of 629 square miles, the Quillayute River Basin provides important habitat for 23 distinct runs of anadromous steelhead and salmon, representing one of the largest and most productive watersheds on the Washington coast (Nelson, 1982; Hunter, 2006). The Quileute Tribe maintains treaty-protected fisheries at usual and accustomed areas in the Quillayute River Basin; however, these fisheries are currently at risk during the late summer as water temperatures within these areas may exceed the specific thermal tolerances of salmonids and other cold-water aquatic species. To inform the planning and prioritization of projects that aim to improve the availability of cold-water habitat in the Quillayute River Basin, the U.S. Geological Survey (USGS), in cooperation with the Quileute Tribe and Wild Salmon Center, utilized various methods to characterize the late-summer water temperature dynamics of the Quillayute River Basin. These study components and their corresponding objectives included the following: - Thermal infrared surveys to map and profile water surface temperatures and identify thermal points of interest in the Quillayute River and its major tributaries (126 river miles total). - Paired air-stream temperature analysis to evaluate the groundwater influence and thermal sensitivity of 11 sites within the Quillayute River Basin. Repeated longitudinal near-surface and near-bottom water temperature float surveys to locate temperature changes indicative of groundwater discharge and assess the tidal influence on water temperatures along the right edge, left edge, and center of the Quillayute River (20 surveys total) - Models of groundwater-surface water exchange using streambed sediment temperature data at 6 sites in the lower Quillayute River and 13 sites in the Quillayute River oxbow ponds. - Cross-sectional profiles of water temperature and specific conductance to support interpretation of continuous water temperature records collected in the Quillayute River oxbow ponds. The data from these study components are included in the Child Items of this Data Release. In addition to the data presented herein, continuous water temperature data at ten sites representing deep pools in the Quillayute River and Quillayute River oxbow ponds were collected and published on the USGS National Water Information System (USGS, 2024a-e, g-k) as part of this study, along with river stage data at an additional site on the Quillayute River (USGS, 2024f). At each of the ten pool sites water temperature was collected at two to three depths in the water column to assess thermal stratification and the potential effect of tides and groundwater discharge. A forthcoming USGS Scientific Investigations Report will provide interpretation of all data published for this study.

This dataset provides a zipfile containing 20 shapefiles with geo-referenced longitudinal water temperature profiles (LTPs; .shp). Profiles were obtained from longitudinal “Lagrangian” drag-probe temperature surveys ("float surveys") of the Quillayute River. Near-streambed and near-surface water temperature and conductivity were measured at three-second intervals and the spatial locations of each measurement was recorded using a GPS from a kayak drifting downstream at ambient stream velocity following the method of Vaccaro and Maloy (2006). The study area consisted of the Quillayute River from its upstream-most point at the confluence of the Sol Duc and Bogachiel Rivers to its outlet at the Pacific Ocean (8 river kilometers). The float surveys were conducted August (Aug.) 10 and 11, 2021, and Aug. 2 and 3, 2022, during different tidal conditions. Three longitudinal profiles were measured near-simultaneously on each survey date, along the left bank, right bank, and thalweg. Each shapefile was named according to the depth of the measurements at near-surface (SRF) or near-streambed (BED), and whether it was along the left bank (L), right bank (R), or thalweg (C). Only twenty profiles are included because data from four surveys was unusable due to sensor malfunction. The missing profiles were from the following dates and sensor locations: Aug. 10, 2021, near-surface left bank; Aug. 10, 2021, near-streambed left bank; Aug. 11, 2021, near-surface right bank; and Aug. 3, 2022, near-streambed left bank. Two of the sensors used in the float surveys had temperature values adjusted by -0.2 degrees Celsius to correct for calibration drift, based on pre-survey verification readings. This correction was applied to the near-streambed thalweg surveys on Aug. 10 and 11, 2021, the near-surface right bank survey on Aug. 10, 2021, the near-streambed left bank survey on Aug. 11, 2021, and the near-surface thalweg and near-streambed right bank surveys on Aug. 2 and 3, 2022. Float surveys targeted a start time in the late morning and an end time in the late afternoon during the diurnal increase in water temperature such that deviations from the diurnal increase may be attributed to groundwater discharge, tributaries, or other sources of water that differ in temperature from the river. The data is projected in UTM10N and the horizontal datum is NAD83(2011).

Abstract: We apply the hydrologic landscapes (HL) concept to assess the hydrologic vulnerability of the western United States (U.S.) to projected climate conditions. Our goal is to understand the potential impacts for stakeholder-defined interests across large geographic areas. The basic assumption of the HL approach is that catchments that share similar physical and climatic characteristics are expected to have similar hydrologic characteristics. We map climate vulnerability by integrating the HL approach into a retrospective analysis of historical data to assess variability in future climate projections and hydrology, which includes temperature, precipitation, potential evapotranspiration, snow accumulation, climatic moisture, surplus water, and seasonality of water surplus. Projections that are not within two-standard deviations of the historical decadal average contribute to the vulnerability index for each metric. The resulting vulnerability maps show that temperature and potential evapotranspiration are consistently projected to have high vulnerability indices for the western U.S. Precipitation vulnerability is not as spatially-uniform as temperature. The highest elevation areas with snow are projected to experience significant changes in snow accumulation. The seasonality vulnerability map shows that specific mountainous areas in the West are most prone to changes in seasonality, whereas many transitional terrains are moderately susceptible. This paper illustrates how the HL approach can help assess climatic and hydrologic vulnerability across large spatial scales. By combining the HL concept and climate vulnerability analyses, we provide a planning approach that could allow resource managers to consider how future climate conditions may impact important economic and conservation resources. Purpose: These data were created in support of the US EPA’s ACE CIVA 2.3, Task Project (QAPP: E-WED-0030854). However, these climate data and hydrologic landscape summaries should have broad applicability for hydrological, geomorphic, or ecological modeling, management, and restoration. This raster contains the modeled change in the seasonality of the month of maximum surplus precipitation between the target modeled time period (in title) and the 1971-2000 Normal period (1 = same season, 0 = earlier season, 2 = later season).
