A wide variety of regional assessments of the water-related impacts of climatic change have been done over the past two decades, using different methods, approaches, climate models, and assumptions. As part of the Water Sector research for the National Assessment of the Implications of Climatic Variability and Change for the United States, several major summaries have been prepared, looking at the differences and similarities in results among regional research projects. Two such summaries are presented here, for the Colorado River Basin and the Sacramento River Basin. Both of these watersheds are vitally important to the social, economic, and ecological character of their regions; both are large snowmelt-driven...

Ponds are impoundments that have been used for flood control, water supply, irrigation, and recreation. They constitute modifications to the stream network that fragment the aquatic habitat by limiting river network connectivity necessary for fish passage. A dataset was developed to quantify small ponds as proxy measures of barriers to flow in stream networks across the State of North Carolina. The USGS used a combination of the 2016 National Land Cover Dataset (NLCD) and the National Hydrography Dataset (NHD) Plus High Resolution to identify 105,560 small ponds that are less than 10 acres in size. The features are more refined than larger scale assessments such as those in the NHDPlus High Resolution and provide...
The U.S. Geological Survey, in cooperation with the California Department of Water Resources (DWR), has constructed a new spatially distributed Precipitation-Runoff Modeling System (PRMS) for the Merced River Basin (Koczot and others, 2021), which is a tributary of the San Joaquin River in California. PRMS is a deterministic, distributed-parameter, physical-process-based modeling system developed to evaluate the response of streamflow and basin hydrology to various combinations of climate and land use (Markstrom and others, 2015). Although further refinement may be required to apply the Merced PRMS for official streamflow forecast operations, this application of PRMS is calibrated with intention to simulate (and...

The geospatial data presented here as ArcGIS layers denote landcover/landuse classifications to support field sampling efforts that occurred within the Cache Creek Settling Basin (CCSB) from 2010-2019. Manual photointerpretation of a National Agriculture Imagery Program (NAIP) dataset collected in 2012 was used to characterize landcover/landuse categories (hereafter habitat classes). Initially 9 categories were assigned based on vegetation structure (Vegtype1). These were then parsed into two levels of habitat classes that were chosen for their representativeness and use for statistical analyses of field sampling. At the coarsest level (Landcover 1), five habitat classes were assigned: Agriculture, Riparian,...
This dataset consists of hydrologically enforced digital elevation model rasters for each 4-digit Hydrologic Unit Code (HUC) area in Maine (0101, 0102, 0103, 0104, 0105, and 0106). The cell size of each raster is 10 meters, and the elevation values are expressed in centimeters. The elevation rasters may be used along with the accompanying data layers in this release to delineate watersheds within the HUC-4 areas.
This data release contains one shapefile describing cattle access to a total of 36 different sub basins within the Shenandoah Watershed located in Virginia and West Virginia. This data release identifies areas in satellite imagery where cattle were observed to have access to the stream (confirmed access), areas where cattle exist, and are not fenced off from the stream (unrestricted access), and areas where cattle do not have access to the stream (restricted access) at the time of imagery capture. Streams were defined using a combination of geospatial data and visually assessing channel morphology in aerial imagery. Cattle access points were determined by visually assessing satellite imagery for barren or disturbed...

This tabular dataset includes measurements of net radiation, air temperature, relative humidity, wind speed, and calculated reference evapotranspiration (ET0) for a bioretention garden in Douglas County, Nebraska. To determine the amount of water that was lost to the atmosphere, evapotranspiration (ET) was calculated at the Eastern Nebraska Office on Aging (ENOA) bioretention garden by scaling the reference evapotranspiration (ET0) by a landscape coefficient. Measurements of net radiation, air temperature, relative humidity, and wind speed were used to calculate daily ET0 using the Penman-Monteith equation (Monteith and Unsworth, 1990; Allen and others, 1998). Reference evapotranspiration represents ET, in inches,...

USGS met with 13 local groups and organizations around the Portland, Oregon region to collect information regarding the locations of beaver dams in the Tualatin Basin. The local sources had identified beaver dams between 2011 and 2019, and data were compiled by USGS into an ArcGIS shapefile. Often, the local groups did not know the GPS coordinates of beaver dams, but they had identified beaver-affected reaches during that same time period. Therefore, a second shapefile was created to include the locations of beaver activity (including beaver chews, lodges, and dams) in the Tualatin Basin. The Beaver Dam Locations ArcGIS shapefile shows the known locations of beaver dams in the Tualatin Basin. The Beaver Activity...
