To help resource managers plan and mitigate long-term drought impacts in the Colorado River Basin, the USGS has launched a platform that brings together science, data, and mapping and analytical tools from across the basin in a central location.

The USGS is conducting research at uranium-bearing breccia pipe deposits to address data gaps related to the potential effects of uranium exploration and mining activities on the Grand Canyon watershed, its people, wildlife, and water resources. Study locations are primarily on Federal lands with a few locations on Tribal lands, and include historic and active mines.

This application highlights modeled flows of the Colorado River for a discharge of 41,000 cubic feet per second (cfs) that is approximate to recent (2012 - 2018) and future anticipated water releases associated with a High Flow Experiments conducted from Glen Canyon Dam near Page, Arizona.  These data are to help visualize the water levels during High Flow Events in relation to othe

This link launches the Grand Canyon Monitoring and Research Center’s discharge, sediment and water quality monitoring application gateway.  Sediment and water quality information can be accessed from here for our on-going monitoring taking place across the Southwest U.S.

Several applications related to the Grand Canyon Monitoring and Research Center’s long-term sandbar monitoring project can be accessed here, including the sandbar area and volume tool and applications highlighting changes to sandbars as a result of High-Flow Events (HFEs) conducted by Glen Canyon Dam near Page, Arizona.

This application allows for the exploration of a select set of insect emergence data collected as part of a citizen science project initiated by the Grand Canyon Monitoring and Research Center (GCMRC).  Data present in this application relate to a recent BioScience publication from USGS scientists and collaborators that investigated the effects of dam operations on downstream aquatic insects.
