Multisource Water-Quality Trends in the Delaware River Basin

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.

North American Bat Monitoring Program (NABat) Partner Portal

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

Measuring stream flow

In this explorable interactive tool you will investigate a series of charts and sliders to explore how water level, water velocity, number of measurement points and stream channel shape influence stream flow. Great for use in the classroom, especially for student curious about coding.

Lowell Minor Planet Services - asteroid.lowell.edu

The USGS Astrogeology Science Center has collaborated with Lowell Observatory to create a graphical interface for their main asteroid characterization web portal. The portal uses data from the astorb database maintained by Lowell Minor Planet Services.

Data Query for the Water Quality of San Francisco Bay Project

Since 1969, USGS has collected water-quality data along the deep-channel longitudinal axis of the San Francisco Bay-Delta system at 37 fixed locations spaced 3-6 kilometers apart. The Water Quality of San Francisco Bay Data Query provides access to the entire dataset.

Fire Danger GACC Regional Forecast Graphs

The GACC Regional Forecast Graphs provide a look at the most recent fire risk outlook in comparison to historical information.

Fire Danger OGC Services

Fire Danger map services are available as Open Geospatial Consortium (OGC) Web Map Service (WMS) services.

Fire Danger Map and Data Products

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

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).

Emergency Assessment of Post-Fire Debris-Flow Hazards: Dolan Fire

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.

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.
