Data

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...

This dataset provides information collected at three stream sites on the lower Yakima River in Washington State during 2018 to 2020 by the U.S. Geological Survey. Sample locations included the Yakima River at Prosser, WA (site ID, 12509489), the Yakima River at Kiona, WA (site ID, 12510500), and the Yakima River at Van Giesen bridge near Richland, WA (site ID, 12511800). Water stargrass...

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...

This data release contains channel cross sections of the Nooksack River near North Cedarville, WA, collected during routine streamgaging and discharge measurement efforts at USGS streamgage 12210700. All cross sections were collected using an acoustic doppler current profiler (ADCP) from the downstream side of the Highway 542 bridge. Raw ADCP measurement data were processed using a...

MODPATH simulations were performed using the MODFLOW groundwater flow model by Wright and others (2023) as the basis, with particles originating from 5 separate areas in or near Joint Base Lewis-McChord (JBLM). Steady-state and transient runs were performed, with transient runs representing 2005-2015 conditions. This data release contains the input and output files for the simulations...
