Data and Tools

The USGS Water Resources Mission Area provides water information that is fundamental to national and local economic well-being, protection of life and property, and effective management of the Nation’s water resources. Below, find data and tools relevant to a wide range of water resources and conditions including streamflow, groundwater, water quality, and water use and availability.

Water-Quality Changes in the Nation's Streams and Rivers

This mapper provides results from the largest-ever assessment of water quality changes in the Nation's streams and rivers. More than 185 million water-quality records from over 600 Federal, State, Tribal, and local organizations were screened as part of this assessment.

Groundwater Quality: Decadal Change

Almost one-half of the U.S. population rely on groundwater for their water supply, and demand for groundwater for public supply, irrigation, and agriculture continues to increase. This mapper shows how concentrations of pesticides, nutrients, metals, and organic contaminants in groundwater are changing during decadal periods across the Nation.

Watershed Regressions for Pesticides (WARP)

The Watershed Regression for Pesticides (WARP) is an online tool that allows users to estimate pesticide concentrations for streams that have not been monitored. WARP models are developed using linear regression methods to establish quantitative linkages between measured pesticide concentrations and a variety of human-related and natural factors that affect pesticides in streams.

Environmental Data Discovery and Transformation (EnDDaT)

Environmental Data Discovery and Transformation (EnDDaT) accesses environmental data from a variety of data sources, compiles and processes the data, and performs common transformations. The result is that data from multiple sources is sorted into a single table that aids model development.

Geo Data Portal

The Geo Data Portal (GDP) provides access to numerous datasets, including gridded data for climate and land use. Datasets can be subsetted or summarized before download using several algorithms, and these algorithms can also be applied to other datasets hosted elsewhere.
