Map of the Upper Colorado River Basin —referred to as an Integrated Water Science (IWS) basins—are intensively monitored study basins representing a wide range of environmental, hydrologic, and landscape settings and human stressors of water resources to improve our understanding of water availability across the Nation.

The U.S. Geological Survey uses a depiction and classification scheme for hydrologic units known as hydrologic unit codes (HUCs). HUCs generally represent catchments, and river basins are represented by a unique series of numbers with successively smaller hydrologic units nested inside of larger ones.

Underside of Bell Jet Helicopter with thermal infrared and true-color image sensors and JN and M.D. The helicopter is used for airborne surveys of river reaches to capture temperature values of water-surfaces.

Schematic diagram of water flow through a conventional copper-ore flotation plant and unlined tailings storage facility illustrating water losses (in italics), reclamation of process water, and addition of makeup water.

Profile view of a Bell Jet Helicopter with a thermal infrared and true-color sensor co-mounted to the underside of the nose. These sensors are used in airborne thermal infrared surveys for remotely sensing land/water surface temperature.

Summer Lake, Oregon is one of the 20 terminal lakes identified by USGS partners as priority ecosystems for study by the Saline Lakes Ecosystems IWAA.

A soil moisture data logger buried in the ground is a specialized instrument designed to measure and record the moisture content of soil over time. Here's how it generally functions:

This map shows the airborne geophysical survey area and planned flight paths across the Illinois River Basin in Illinois and northwest Indiana. Surveys will not occur directly above populated areas. Planned flight lines and survey progress can be found online.

Steamboat Geyser eruption signals recorded by nearby monitoring instruments. The vertical pink lines mark when the signal first appears. (A) Seismic station YNM records a signal which slowly tapers as the eruption decreases in intensity. Spikes seen before the eruption are mostly due to human activity.
