Data

Warming climates, declining winter snowpacks, and increased periods of drought have contributed to warming stream temperatures and declining stream flows, impacting habitat availability for cold water species. Particularly in the northern Great Basin region available habitat may be restricted to headwaters, where cooler temperatures and reliable stream flows allow cold water species...

These data were collected as part of a larger project to support Total Maximum Daily Load (TMDL) modeling in the Big Soos Creek basin. Water temperature, air temperature and sensor depth were collected from four sites in the Big Soos Creek basin; LITTLE SOOS CREEK BELOW LAKE YOUNGS NEAR KENT, WA (USGS site ID 12109400), JENKINS CREEK AT 188TH AVE SE NEAR KENT, WA (USGS site ID 12110300)...

These data sets have at-site values of probability differences and entropy-based metrics to compare the effects of streamflow resolution, monitoring period, and record extension instead of monitoring on streamflow information. Source code for the R functions used to calculate conditional probabilities, conditional entropy, and mutual information are included in a compressed file with...

This data release includes estimated Self-Calibrated Palmer Drought Severity Index (scPDSI) values and ancillary information for three data products that had previously been developed for the Pacific Northwest Region (HUC 17). The data products are stored in three child items: 1. National Hydrography Dataset High Resolution Flowlines: This child item contains the flowlines in the...

Particulate samples were collected from a fish hatchery in Puyallup, Washington, September 18 – 20, 2023 during late summer, low-flow conditions in the intake creek. Settled solids were collected from a retention pond and from the incubation room trough. The trough solids likely had been deposited during storm events the previous winter. A third sample was collected in the incubation...

A three-dimensional groundwater flow model, constructed in MODFLOW-NWT, was developed to evaluate the groundwater flow system of the Kitsap Peninsula, west-central Washington. A transient model was constructed to simulate groundwater flow for January 1985–December 2012 using annual stress periods for 1985–2004 and monthly stress periods for 2005–2012. The model was used to simulate six...

This Data Release contains supporting data to evaluate fine sediment infiltration into gravels in identified locations of Chinook spawning habitat at three sites on the Sauk River, located in western Washington. Fine sediment infiltration into the river substrate that salmonid fish species use to spawn has been shown to increase mortality during the incubation and pre-emergence phase...

This data release contains the results from hydrograph separation analysis for 44 separate sites within the Columbia Plateau region of the Pacific Northwest. The hydrograph separation program (HYSEP) (Sloto and Crouse, 1996) was used to perform baseflow separation. HYSEP is an automated approach to traditional graphical hydrograph separation methods and was utilized for this study. For...

The U.S. Geological Survey (USGS), in cooperation with the Washington State Department of Ecology (Ecology), conducted a study to describe the current understanding of the regional groundwater system of the lower Duwamish River valley and groundwater and surface-water interactions in the lower Duwamish Waterway. A nearshore site along the western shoreline of the Duwamish River, about 1...

The U.S. Army Corps of Engineers Fish Passage Facility, located on the White River, Washington State, collects upstream-migrating fish and transfers them to trucks, allowing the fish to access the watershed upstream of Mud Mountain Dam. The structure, constructed in 2019, includes an impoundment held by gates that can be raised or lowered remotely. Those gates are typically lowered...

The data within this data release presents information used to characterize the groundwater-flow system and the development of a groundwater-flow model in the active model area. Conceptual and numerical models of groundwater flow were developed by the U.S. Geological Survey Washington Water Science Center, in close cooperation with 18 water-resource agencies and stakeholders, to assess...

Water temperature is an important characteristic of stream conditions with implications for water quality and stream dwelling organisms. This Data Release contains spatial stream network (SSN) objects and R scripts to run SSN models to predict mean monthly stream temperature and 7-day average daily maximum (Max7DAD) during August and September in the White River watershed within Mount...
