Interactive Maps

The GAMA-PBP Public-Supply Well Results data viewer allows the user to visualize and download California water-quality data and trends for1974 - 2014. Groundwater-quality data for 38 inorganic constituents are captured and can be downloaded for individual sites or by grid cell. 

Developed by Lower Mississippi-Gulf scientists, these visual flood warning maps empower citizens, federal, state, and local partners to understand flood risks in Louisiana.

This story map explores the role USGS scientists play in understanding the risks presented by avian influenza, and how their work is being used to predict areas of transmission risk.

Compares Anza Valley, CA land use data within the USGS study boundaries for 5 time periods between 1934 and 2005.

2012 SPARROW (SPAtially Referenced Regressions On Watershed attributes) interactive mappers are available for 5 regions of the conterminous U.S. These mappers simulate river streamflow, and nutrient and sediment loads and yields, that would occur under long-term average hydrologic conditions for the time period 1999 through 2014, and source inputs that occurred during or near 2012.

The Texas Water Dashboard presents USGS real-time stream, lake and reservoir, precipitation and groundwater data for more than 850 USGS real-time observation stations in Texas.

SPARROW model results of long-term mean-annual total nitrogen and total phosphorus in streams of the Midcontinental Region of North America. The simulated loads represent source inputs similar to 2002 and normalized to long-term average hydrologic conditions for the period from 1970 to through 2012.
