Groundwater level trends for 110 U.S. Geological Survey observation wells in the Delaware River Basin This data release contains groundwater level trend results from 110 U.S. Geological Survey (USGS) observation wells in and near the Delaware River Basin. Mean annual groundwater level elevations from water years 2000-2020 were computed from mean daily recorded groundwater levels and discretely measured groundwater levels. Both time series were analyzed using the Mann-Kendall test for monotonic trend and the Thiel-Sen slope. Wells are completed in both confined and unconfined aquifers. Data include well identification number, latitude, longitude, aquifer type, trend slopes and p-values for both mean annual time series at 110 wells.

The National Hydrologic Model database contains parameters for hydrologic response units (HRUs) and stream segments needed to run the NHM. These parameters are generated using python scripts to process input datasets such as digital elevation models, soil maps, and land cover classifications.

A statistical machine learning technique - random forest modeling (Liaw and Wiener, 2018; R Core Team, 2020) - was applied to estimate natural flows using about 150 potential predictor variables (Miller and others, 2018). Calibration data used for the random forest model are available from (Foks and others, 2020). Each model was run twice, first using all potential predictor variables, which represents a "full" model run, and a second time using the top 20 predictors from the original run, which...

This data release focuses on definitions and metrics of resilience in water management institutions. Water resource managers, at various scales, are tasked with making complex and time-sensitive decisions in the face of uncertainty, competing objectives, and difficult tradeoffs. To do this, they must incorporate data, tacit knowledge, cultural and organizational norms, and individual or institutional values in a way that maintains consistent and predictable operations under normal circumstances, while...

Working in cooperation with local, State, and Federal agencies, the USGS has published an estimate of water use in the United States every 5 years, beginning in 1950. These 5-year compilations contain water-use estimates that are aggregated to the county level in the United States. This USGS data release contains summaries of method codes used in the 2015 national compilation of public supply, self-supplied domestic, thermoelectric, and irrigation water-use data.

The GFv1.1 is an update to the original Geospatial Fabric (GFv1, Viger and Bock, 2014) for the National Hydrologic Modeling (NHM). Analogous to the GFv1, the GFv1.1 described here includes the following vector feature classes: points of interest (POIs_v1_1), a stream network (nsegment_v1_1), and hydrologic response units (nhru_v1_1), with several additional ancillary tables. These data are contained within the Environmental Systems Research Institute (ESRI) geodatabase format (GFv1.1.gdb).

The output data distinguish between native and reusable streamflow. Native streamflow is that which originates naturally within the watershed. Reusable streamflow originates as water imported from outside the watershed, water derived from pumping of certain groundwaters, or as other water with rights that allow it to be reused. The program accounts for reusable water throughout the watershed, as well as the total inflow and outflow of water to each subreach division within the watershed.

These metrics are computed for every 10 years from 1800 - 2015. The first metric (DamIndex_EROM.zip) estimates reservoir storage intensity in units of days based on reservoir storage in a contributing area normalized by the mean annual streamflow. This metric indicates the duration of storage impact upstream from each stream segment relative to the typical flow condition. In addition, this metric provides an assessment of the potential influence of a dam on average and low flows because the metric estimates the...
