The Texas Water Dashboard presents USGS real-time stream, lake and reservoir, precipitation and groundwater data for more than 850 USGS real-time observation stations in Texas.

SPARROW model results of long-term mean-annual total nitrogen and total phosphorus in streams of the Midcontinental Region of North America. The simulated loads represent source inputs similar to 2002 and normalized to long-term average hydrologic conditions for the period from 1970 to through 2012.

Locations of active wells (at least one measurement during the previous year) in the New England groundwater level network at the end of 2017. The dataset contains 104 wells with continuous water-level measurements (15-minute to hourly measurements), 182 wells with discrete water-level measurements (monthly measurements at most locations), and 95 wells with intermittent water-level measurements.

This application includes information about ongoing or completed groundwater studies in Washington. Included are studies from coastal areas, the densely populated Puget Sound, central and eastern Washington, and cross-boundary areas shared with Canada, Oregon, and Idaho.

The Regional Stream Quality Assessment (RSQA), part of the National Water Quality Assessment project, seeks to characterize multiple water-quality factors that are stressors to aquatic life (contaminants, nutrients, sediment, and streamflow alteration) and to develop a better understanding of the relation of these stressors to ecological conditions in streams throughout the region.
