The PeakFQ application performs peak-flow frequency analysis to evaluate flood frequency on rivers and streams.

This data visualization displays the results of distribution models for 130 snake and lizard species in western North America under six time-by-climate scenarios.

The Fairfax Water Quality Dashboard provides access to water quality data from 6 intensive monitoring stations and 15 trend monitoring stations in Fairfax County.

The Hampton Roads Water Quality Dashboard displays data from 12 water-quality monitoring stations across the cities of Chesapeake, Hampton, Newport News, Norfolk, Portsmouth, and Virginia Beach. This application provides access to current conditions at each monitoring station and visualize timeseries plots for continuously monitored parameters collected at each monitoring stations.

To understand the contamination caused by historic mining in California, researchers sampled sediment, water, and biota (animals) during the years 1999–2004 and 2011–2012. From the data collected, a set of interactive maps were produced. The maps, along with the data release and introductory video, explain the results of the research.

The Landsat Reprocessing Application allows you to discover scene and tile products that have been changed by reprocessing.

This application provides access to estimates of depth-to-water and the water-table elevation for the Portland, Oregon, metropolitan area.

Hawaiian coastal wetlands provide important habitat for endangered waterbirds and socio-cultural resources for Native Hawaiians. Currently, they are degraded by development, sedimentation, and invasive species and, thus, require restoration. Site prioritization represents both an actionable plan for coastal wetland restoration and an alternative protocol for restoration decision-making.

Inland recreational fishing is often conceived as primarily a leisure-driven activity in freshwaters, yet it can contribute substantially to food systems. This tool explores nutrition, economic value, and climate vulnerability of inland recreational consumption by country.

The USGS EROS Cal/Val Center of Excellence (ECCOE) Landsat Cal/Val Team, along with their NASA counterparts, maintains primary responsibility for radiometric and geometric characterization and the calibration and validation of the Landsat instruments and spacecrafts. This work includes both the ongoing operations of active Landsat missions, as well as the retired Landsat missions.

New Jersey Groundwater Levels and Trends provides access to groundwater-level data from continuous groundwater wells across New Jersey. Recent water-level measurements for all wells considered are compared to long-term monthly statistics and are classified and visualized according to water-level conditions relative to those statistics.

The Philadelphia Water Department (PWD) and USGS have been working together to create and expand the water-quality monitoring network for Philadelphia. Data from these gaging stations will allow PWD scientists and engineers to monitor spatial and temporal water quality/quantity trends in support of watershed restoration initiatives occurring in Philadelphia.
