National Streamflow Statistics Program (NSS)

The USGS develops regression equations for estimating streamflow statistics for every state, Puerto Rico, and a number of metropolitan areas in the U.S. These equations have been compiled into the National Streamflow Statistics (NSS) Program for design, planning, management, and regulatory purposes. These estimates are often needed at ungaged sites where no observed flow data are available....

The Groundwater Toolbox: A Graphical and Mapping Interface for Analysis of Hydrologic Data

The Groundwater Toolbox is a graphical and mapping interface for analysis of hydrologic data. It provides methods to estimate many of the components of the water budget for a hydrologic basin, including precipitation, streamflow, base flow, runoff, groundwater recharge and evapotranspiration.

Wellfootprint - A Map App for Visualizing Groundwater Withdrawals

Wellfootprint computes a raster map of groundwater withdrawals relative to a user-defined "Depth-Rate Index" (DRI), such as a recharge rate. Dividing each well's withdrawal rate by the length per time DRI yields an area for display for each well's 'footprint' as a circle around each well. Symbols for closely spaced wells are merged to visualize the combined withdrawals equitably.
