StreamStats provides access to spatial analytical tools providing USGS water science-backed information that are useful for water-resources planning and management, and for engineering and design purposes.

Flood Inundation Mapper

The USGS Flood Inundation Mapper combines flood inundation map libraries with real-time USGS river-level data and National Weather Service flood forecasts into a powerful tool that helps communicate when and where flooding may occur and better inform local responses that can protect lives and property.


SPARROW is a collection of tools for relating water-quality monitoring data and watershed attributes. Sparrow models are designed to describe the spatial patterns of water quality and the factors that affect it. WIM has partnered with SPARROW scientists to provide a suite of map applications depicting SPARROW models for different regions of the U.S. and parts of Canada.


WHISPers is the Wildlife Health Information Sharing Partnership event reporting system. It web application exposing wildlife mortality data submitted by partners across North America and verified by trained biologists.

Wetlands Inventory

The U.S. Fish and Wildlife Service is the principal federal agency that provides information to the public on the extent and status of the Nation's wetlands. The agency has developed a series of topical maps to show wetlands and deepwater habitats which can be viewed and downloaded through the wetlands mapper.

NAWQA Surface Water Quality Trends

This USGS Water-Quality Changes in the Nation’s Streams and Rivers 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.
