Both the GOA 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 America.

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.

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.

Careful observation and analysis of the movement and condition of surface water is essential for understanding this resource, especially during times of drought. The California Water Science Center uses a network of more than 500 streamgages to collect real-time data on surface water at locations across the state.

The EDNA Watershed Atlas contains watershed characteristics for major named rivers of the contiguous U.S. including maps, images, legends, and statistics derived from the EDNA Watershed Characteristics model.
