Data collected in 2008-2010 to evaluate juvenile salmon and forage fish use of eelgrass on the Skagit River Delta, Washington State, USA Data collected in 2008-2010 to evaluate juvenile salmon and forage fish use of eelgrass on the Skagit River Delta, Washington State, USA
Data are abundance and body size (length) of juvenile salmon, forage fish, and other species captured with a lampara net in eelgrass and nearby unvegetated habitat on the Skagit River Delta monthly, April-September, 2008-2010, as well as vegetation status, water depth, temperature, salinity, and clarity for each fish netting event.
High-resolution bathymetry and acoustic-backscatter data collected in 2004, 2005, 2007, and 2010 in Skagit Bay, Washington High-resolution bathymetry and acoustic-backscatter data collected in 2004, 2005, 2007, and 2010 in Skagit Bay, Washington
This data release provides the U.S. Geological Survey (USGS) Pacific Coastal and Marine Science Center (PCMSC) 2004, 2005, 2007, and 2010 bathymetry data that was collected in Skagit Bay, Washington as well as a merged 2005-2010 bathymetry grid. Also, this data release provides the acoustic-backscatter as a merged 2005-2010 backscatter image. All bathymetry grids are provided at 1-m...
Stage, water velocity and water quality data collected in the Lower Nisqually River, McAllister Creek and tidal channels of the Nisqually River Delta, Thurston County, Washington, February 11, 2016 to September 18, 2017 (ver. 1.1, December, 2019) Stage, water velocity and water quality data collected in the Lower Nisqually River, McAllister Creek and tidal channels of the Nisqually River Delta, Thurston County, Washington, February 11, 2016 to September 18, 2017 (ver. 1.1, December, 2019)
This data release includes time series data of stage, water velocity and water quality parameters at multiple locations in the tidally-influenced reaches of the Nisqually River and McAllister Creek, and tidal channels of the Nisqually River Delta. In total, time series data were collected at multiple sites from February 11, 2016 to March 19, 2018 during separate but generally overlapping...

Assessing tidal marsh vulnerability to sea-level rise in the Skagit Delta Assessing tidal marsh vulnerability to sea-level rise in the Skagit Delta
Historical aerial photographs, from 1937 to the present, show Skagit Delta tidal marshes prograding into Skagit Bay for most of the record, but the progradation rates have been steadily declining and the marshes have begun to erode in recent decades despite the large suspended sediment load provided by the Skagit River. In an area of the delta isolated from direct riverine sediment...

Suspended sediment delivery to Puget Sound from the lower Nisqually River, western Washington, July 2010–November 2011 Suspended sediment delivery to Puget Sound from the lower Nisqually River, western Washington, July 2010–November 2011
On average, the Nisqually River delivers about 100,000 metric tons per year (t/yr) of suspended sediment to Puget Sound, western Washington, a small proportion of the estimated 1,200,000 metric tons (t) of sediment reported to flow in the upper Nisqually River that drains the glaciated, recurrently active Mount Rainier stratovolcano. Most of the upper Nisqually River sediment load is...

Changes in habitat availability for outmigrating juvenile salmon (Oncorhychus spp.) following estuary restoration Changes in habitat availability for outmigrating juvenile salmon (Oncorhychus spp.) following estuary restoration
The restoration of the Nisqually River Delta (Washington, U.S.A.) represents one of the largest efforts toward reestablishing the ecosystem function and resilience of modified habitat in the Puget Sound, particularly for anadromous salmonid species. The opportunity for outmigrating salmon to access and benefit from the expansion of available tidal habitat can be quantified by several...

Impacts of Climate Change on Regulated Streamflow, Hydrologic Extremes, Hydropower Production, and Sediment Discharge in the Skagit River Basin Impacts of Climate Change on Regulated Streamflow, Hydrologic Extremes, Hydropower Production, and Sediment Discharge in the Skagit River Basin
Previous studies have shown that the impacts of climate change on the hydrologic response of the Skagit River are likely to be substantial under natural (i.e. unregulated) conditions. To assess the combined effects of changing natural flow and dam operations that determine impacts to regulated flow, a new integrated daily-time-step reservoir operations model was constructed for the...

Combined effects of projected sea level rise, storm surge, and peak river flows on water levels in the Skagit Floodplain Combined effects of projected sea level rise, storm surge, and peak river flows on water levels in the Skagit Floodplain
Current understanding of the combined effects of sea level rise (SLR), storm surge, and changes in river flooding on near-coastal environments is very limited. This project uses a suite of numerical models to examine the combined effects of projected future climate change on flooding in the Skagit floodplain and estuary. Statistically and dynamically downscaled global climate model...
