Interactive Maps

Water quality is essential for understanding water availability by providing insights into the drivers of change and possible availability constraints. Using data from eight monitoring organizations including the USGS, the Multisource Water-Quality Trends in the Delaware River Basin mapper shows changing water-quality trends from 2008-2018 in rivers and streams across the Delaware River Basin.

NABat is an international and interagency program that aims to conserve North American bat populations by providing standardized survey data from across the continent.

The Map and Data Products page offers bulk download of the Fire Danger Forecast data suite.

This interactive map depicts the likelihood of debris-flow generation and estimates of flow magnitude in locations where debris flows initiate. The models do not predict downstream impacts, potential debris-flow runout paths, and the areal extent of debris-flow or flood inundation.

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.

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.

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.

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.

The Flycatcher Habitat Viewer was developed to meet the needs of organizations by providing maps of predicted flycatcher breeding habitat throughout its range. Maps are provided from 2013 to present and cover 57 satellite scenes. Maps identify predicted flycatcher habitat based upon the amount of green vegetation within a 120-m radius of each cell, and the size of floodplain within a 360-m radius.

Launched on September 27th, 2021, Landsat 9 is a partnership between NASA and the U.S. Geological Survey. Learn about the process of building Landsat 9 and how it will extend Landsat's unbroken record of our planet to over half a century.

Data visualization tool created for California's Bay-Delta Regional Monitoring Program. This web applicaton visualizes nutrients and phytoplankton spatially and temporally.

The U.S. Wind Turbine Database (USWTDB) Viewer lets you visualize, inspect, interact, and download the most current onshore and offshore turbine locations in the United States, corresponding facility information, and turbine technical specifications through a dynamic web application. The Viewer provides direct access to data and information stored within the USWTDB.
