Both the GOM Dashboard and the Sea-level Tool feature interactive maps for viewing either water data and associated weather data or the potential for flooding. Both maps are specific to regions along the Gulf of Mexico.

The Biomonitoring of Environmental Status and Trends (BEST) Program's Large River Monitoring Network (LRMN) has examined fish health in multiple river basins by using a suite of organismal and suborganismal endpoints, which monitor and assess the effects of environmental contaminants in fish.

This site provides hydrologic data collected or compiled by the USGS in the Yucaipa area; some additional data may be available from the USGS database National Water Information System (NWIS).

The Geologic CO2 Sequestration interactive web map includes investigated basins, assessed areas, stratigraphic columns, and well density information.

This website is a data visualization companion to the U.S. Geological Survey (USGS) report titled Federal Lands Greenhouse Gas Emissions and Sequestration in the United States: Estimates 2005-14. The maps and charts on this site include the estimated emissions and sequestration from both fossil fuel activities and ecosystem processes on Federal lands only.

The following graphs show water surface elevations above NGVD 1929 in selected reservoirs for several years, including 2015. The purpose of these graphs is to compare water surface elevations during 2015 with water surface elevations observed during years when documented droughts have occurred.

The Water Level and Salinity Analysis Mapper is designed to conduct automated statistical and graphical analyses on water-level and salinity data collected from sites monitored by the U.S. Geological Survey (USGS) in South Florida.

The quality of groundwater in the Borrego Valley is a concern because it is the sole source of water for agricultural, recreational, and public supply. Explore the interactive water-quality data map for detailed information and to download data.

The Multi-Resolution Land Characteristics (MRLC) consortium is a group of federal agencies who coordinate and generate consistent and relevant land cover information at the national scale for a wide variety of environmental, land management, and modeling applications.

A geonarrative (Esri Story Map) describing what it might be like the next time the Hayward fault has a large earthquake. Scientists examined a hypothetical earthquake, the magnitude 7.0 HayWired earthquake scenario.

Long-term groundwater-level data are fundamental to the resolution of problems dealing with groundwater availability and sustainability. Significant periods of time typically are required to collect water-level data needed to assess the effects of climate variability, to monitor the effects of regional aquifer development, or to obtain data sufficient for analysis of water-level trends.

Streams, rivers, lakes and reservoirs are important natural resources for irrigation, public supply, wetlands and wildlife.  Excess precipitation that flows into these sources is called runoff, and it's an important drought indicator.  The California Water Science Center tracks both monthly and annual runoff.
