A three-dimensional groundwater flow model was developed in 1997 to evaluate the groundwater flow system at Puget Sound Naval Shipyard, Naval Base Kitsap, Bremerton, Washington (https://pubs.er.usgs.gov/publication/wri964147). In 2016, a regional groundwater flow model for the greater Kitsap Peninsula was developed (https://pubs.er.usgs.gov/publication/sir20165052). Using information from the 2016 regional model, the 1997 groundwater flow model for the Puget Sound Naval Shipyard was updated with a new interpretation of the underlying hydrogeologic units, a refined model grid, and improved recharge estimates. A steady-state model version was constructed in MODFLOW-NWT to simulate equilibrium conditions. MODPATH forward...

The Klickitat mule deer herd inhabits the Columbia Hills and surrounding terrain to the north along the Columbia River, Washington (fig. 23). The Klickitat River is the western boundary of the herd and is part of a transition zone between black-tailed deer and mule deer distributions. Habitats in the western half of the herd’s range include Quercus garryana (Oregon white oak) mixed with Abies spp. (fir), pine, or grassland species. The western half of the herd’s range comprises a mix of public and private lands, including rangeland, farmland, and the Klickitat Wildlife Area, which has protected crucial winter range since the 1950s. Sagebrush steppe is more prevalent in the eastern half of the herd’s range with Quercus...

The Colockum elk herd inhabits a mix of public and private lands northeast of Ellensburg between Blewett Pass of the Cascade Range and west of the Columbia River (fig. 35). The population ranges between 4,000 and 5,000 animals and is partially migratory, with individuals displaying a mix of resident (63 percent of analyzed individuals) and migratory (34 percent of analyzed individuals) behaviors. During winter, many elk inhabit grassland, sagebrush, antelope bitterbrush, and ponderosa pine habitats in the Whiskey Dick, Quilomene, and Colockum Wildlife Areas and the eastern reaches of the Naneum State Forest. As spring green up of vegetation nears, migratory elk travel northwest toward summer ranges in the Wenatchee...

This data release contains reference baselines for primarily open-ocean sandy beaches along the west coast of the United States (California, Oregon and Washington). The slopes were calculated while extracting shoreline position from lidar point cloud data collected between 2002 and 2011. The shoreline positions have been previously published, but the slopes have not. A reference baseline was defined and then evenly-spaced cross-shore beach transects were created. Then all data points within 1 meter of each transect were associated with each transect. Next, it was determined which points were one the foreshore, and then a linear regression was fit through the foreshore points. Beach slope was defined as the slope...

The depths to a high and average water table below the land surface were estimated across the Clover Creek watershed in Pierce County, Washington. Groundwater model simulations provided initial estimates of water-table depths for the analysis. To provide optimized, data-driven estimates of these depths, a continuous bias correction surface was applied to model output according to differences between simulated and observed water levels at observation wells.

Note: This data release is currently under revision and is temporarily unavailable. Phenological dynamics of terrestrial ecosystems reflect the response of the Earth's vegetation canopy to changes in climate and hydrology and are thus important to monitor operationally. The Exotic Annual Grass (EAG) phenology in the western U.S. rangeland based on 30m near seamless Harmonized Landsat and Sentinel-2 (HLS) Normalized Difference Vegetation Index (NDVI) weekly composites between 2016 and 2021 (Dahal et al., 2022) were processed using these 3 methods: (1) NDVI threshold-based method, (2) manual phenological metrics, and (3) modeling and mapping. The EAG phenology model produced eight metrics identifying the sustainable...

The Wenatchee Mountains mule deer herd inhabits a matrix of private and public lands along the eastern slope of the Cascade Range in Chelan and Kittitas Counties in Washington (fig. 24). Historically, the Wenatchee Mountains mule deer herd was separated into two subherds, Chelan and Kittitas; however, recent GPS collar data indicated the mule deer south of U.S. Highway 2 and north of Interstate 90 represent one population. Their high-use winter range extends along the foothills west and south of Wenatchee, Washington and throughout the foothills of the Kittitas Valley near Ellensburg. Their low-use winter range occurs along the foothills west of the Columbia River north of Interstate 90. In the spring, migratory...

Climate change is one of the most pressing issues facing resource management. The disruptions it is causing require that we change the way we consider management in order to ensure the future of habitats, species, and human communities. Practitioners often struggle with how to identify and prioritize specific climate adaptation actions (CAAs). Management actions may have a higher probability of being successful if they are informed by available scientific knowledge and findings. The goal of the Available Science Assessment Process (ASAP) was to synthesize and evaluate the body of scientific knowledge on specific, on-the-ground CAAs to determine the conditions, timeframes, and geographic areas where particular CAAs...

Post-fire shifts in vegetation composition will have broad ecological impacts. However, information characterizing post-fire recovery patterns and their drivers are lacking over large spatial extents. In this analysis we used Landsat imagery collected when snow cover (SCS) was present, in combination with growing season (GS) imagery, to distinguish evergreen vegetation from deciduous vegetation. We sought to (1) characterize patterns in the rate of post-fire, dual season Normalized Difference Vegetation Index (NDVI) across the region, (2) relate remotely sensed patterns to field-measured patterns of re-vegetation, and (3) identify seasonally-specific drivers of post-fire rates of NDVI recovery. Rates of post-fire...

Since the late 1950s, the USGS has maintained a long-term glacier mass-balance program at three North American glaciers. Measurements began on South Cascade Glacier, WA in 1958, expanding to Gulkana and Wolverine glaciers, AK in 1966, and later Sperry Glacier, MT in 2005. The Juneau Icefield Research Program has measured surface mass balance on Lemon Creek and Taku Glacier since the mid-1940s, with USGS providing complimentary seasonal measurements of Lemon Creek beginning in 2014 (JIRP; Pelto and others, 2013). Direct field measurements of point glaciological data are combined with weather and geodetic data to estimate the seasonal and annual mass balance at each glacier in both a conventional and reference surface...
