Georgia Water Use

The U.S. Geological Survey (USGS) South Atlantic Water Science Center and the Environmental Protection Division of the Georgia Department of Natural Resources have been collecting and compiling water-use information in Georgia since 1980 as part of an ongoing cooperative agreement.

Gulf Coast Monitoring and Assessment Program (CMAP)

Explore the inventory of Gulf Coast habitat monitoring, mapping, and water quality programs and assessments compiled by the RESTORE Council Monitoring and Assessment Program (CMAP).

Surface Water Flow Trends in the Nation's Streams and Rivers

Changes in streamflow conditions can affect infrastructure, water supply, and ecosystems. The IWAAs Surface Water Flow Trends mapper provides access to information about long-term changes in low flows, mean flows, and peak flows. View national trends for the last 100, 75, or 50 years, or calculate trend values for a custom time period at an individual site.

Hydrogeology of the Adelaida Area, San Luis Obispo County, CA

The USGS is conducting a comprehensive evaluation of groundwater resources of the Adelaida area. Use this map to explore the hydrogeology of the area, including land use, geology, and USGS hydrologic data by watershed or water management district. 

TrendPowerTool: A web lookup tool for estimating the statistical power of a monitoring program to detect population trends

A simulation-based power analysis can be used to estimate the sample sizes needed for a successful monitoring program, but requires technical expertise and sometimes extensive computing resources. We developed a web-based lookup app, called TrendPowerTool.

LCMAP CONUS Mosaic Download Portal

A web based application used for searching and downloading LCMAP science products at the Conterminous United States (CONUS) scale. 

Model archive for analysis of long-term annual yields of highway and urban runoff in selected areas of California with the Stochastic Empirical Loading and Dilution Model (SELDM)

This model archive describes approaches used by the U.S. Geological Survey in cooperation with CalTrans for assessing long-term annual yields of highway and urban runoff in selected areas of California with version 1.1.0 of the Stochastic Empirical Loading and Dilution Model (SELDM). 

Storm Summary Timelapse Dashboard (SSTL)

Many USGS water-resource monitoring sites have webcams installed to allow remote visibility of current water and environmental conditions, identify technical issues, verify remote measurements, and gather data for visual analyses. The Storm Summary Timelapse Dashboard (SSTL) displays many of these active webcams and provides access to still-frame images and timelapse videos of recent conditions.

How Wildfires Threaten U.S. Water Supplies

The 2020 fire season provided stark evidence that wildfires are changing the landscape of America. But when a forest burns, the impacts on water supply and quality last long after the flames go out. Learn more about how wildfires threaten U.S. water supplies – and what we can do to adapt to the complex impacts of hotter and bigger fires.
