Groundwater, Surface water and Tidal Time Series Data at OU1 Naval Base Kitsap, Keyport, WA
This Data release includes time series data collected at Operable Unit 1, Naval Base Kitsap, Keyport, WA and bounding surface water bodies over a 3 week period from 07/12/2018 to 08/08/2018. Groundwater altitudes in nineteen monitoring wells and surface water altitude and water quality parameters in five surface water bodies were monitored. Time series data were collected covered a period that...
Groundwater and Tidal Time Series Data, Operable Unit 2, Area 8, Naval Base Kitsap, Keyport, Washington
This Data release includes time series data collected at Operable Unit 2, Area 8, at Naval Base Kitsap, Keyport, WA. Groundwater elevations and water quality parameters in five monitoring wells, along with tide levels in Port Orchard Bay, were monitored every 15 minutes during a 3-week duration. Time series data were collected from October 24, 2017, to November 16, 2017, a period that included...
Bathymetric Data Collected for Pre-levee Repair in the Green River near Tukwila, Washington on 20150730
Field Data: The first ADCP data collection effort for this project was done on July 30th, 2015 represented with these bathymetric point locations on the Green River near Tukwilla, WA. Stream surface conditions in the vicinity of the project area were relatively flat and water clarity was good. The upstream and downstream extent of the fishing site was identified by the Muckleshoot’s...
Bathymetric Data Collection Approx. One Year after Levee Work Completion in the Green River near Tukwila, Washington on 20160927
Field Data The fourth ADCP data collection effort for this project was done on September 27th, 2016 represented by these bathymetric point locations on the Green River near Tukwila, WA. Stream surface conditions in the vicinity of the project area were relatively flat and water clarity was good. The upstream and downstream extent of the fishing site was identified by the Muckleshoot’...
Bathymetric Data Collection during high-flow event in the Green River near Tukwila, Washington on 20160121
Field Data: The second ADCP data collection effort for this project was done on January 21, 2016 represented with these bathymetric point locations on the Green River near Tukwila, WA. The stream surface in the vicinity of the project area was relatively flat and water clarity was fair. Stream stage (water-level elevation) was 6.83 ft. higher relative to the July 2015 ADCP data collection...
Bathymetric Data Collection for Post-levee Repair in the Green River near Tukwila, Washington on 20160512
Field Data The third ADCP data collection effort for this project was done on May 12, 2016 represented by these bathymetric point locations on the Green River near Tukwila, WA . The stream surface in the vicinity of the project area was flat and water clarity was good. The upstream and downstream extent of the fishing site was identified by the Muckleshoot’s fisheries biologist...
Analysis of groundwater response to tidal fluctuations, Operable Unit 1, Naval Base Kitsap, Keyport, Washington
Chlorinated volatile organic compounds have affected groundwater beneath a former 9-acre landfill at Operable Unit 1 (OU 1) of Naval Base Kitsap (NBK) Keyport, in Keyport, Washington. The landfill was the primary disposal area for domestic and industrial waste generated by NBK Keyport from the 1930s through 1973. Naval Facilities Engineering...

Analysis of groundwater response to tidal fluctuations, Site 10 Naval Magazine Indian Island, Port Hadlock, Washington
Site 10 at Naval Magazine Indian Island is an approximately 3.7-acre inactive landfill. The site was used as the primary landfill for the island from about 1945 until the mid-1970s, receiving paints, batteries, trash, and materials. In a memorandum to Washington State Department of Ecology, Naval Facilities Engineering Command Northwest (NAVFAC NW...

Water temperature in the Lower Quinault River, Olympic Peninsula, Washington, June 2016 - August 2017
The availability of cold-water refugia during summertime river-water temperature maximums is important for cold-water fish species including Endangered Species Act listed salmonids since water temperature influences metabolism, growth, and phenology. The U.S. Geological Survey monitored water temperature at 10 sites approximately evenly-spaced...

Analysis of groundwater response to tidal fluctuations, Operable Unit 2, Area 8, Naval Base Kitsap, Keyport, Washington
Operable Unit 2, Area 8, at Naval Base Kitsap, Keyport is the site of a former chrome-plating facility that released metals (primarily chromium and cadmium), chlorinated volatile organic compounds, and petroleum compounds into the local environment. To ensure long-term protectiveness, as stipulated in the Fourth Five-Year Review for the site,...

Water temperature profiles for reaches of the Raging River during summer baseflow, King County, western Washington, July 2015
Re-introducing wood into rivers where it was historically removed is one approach to improving habitat conditions in rivers of the Pacific Northwest. The Raging River drainage basin, which flows into the Snoqualmie River at Fall City, western Washington, was largely logged during the 20th century and wood was removed from its channel. To improve...

Thermal profiles for reaches of Snee-Oosh and Fornsby Creeks, Swinomish Indian Reservation, northwestern Washington, July 2013
Longitudinal profiles of streambed temperatures were measured in approximately 225-m-long reaches of the Snee-Oosh and Fornsby Creeks in the Swinomish Indian Reservation, northwestern Washington, during July 2013, to provide information about areas of groundwater discharge to streams. During summer, groundwater discharge is a source of cold water...
