Surface Water

An important part of the USGS mission is to collect scientific data about the nation's water resources. Streamflows (discharge) are one of the most fundamental components needed. To continually assess the nation's surface-water resources, the USGS operates and maintains a vast network of real-time streamgages throughout the country. The USGS also monitors lakes and reservoirs, and engages in many site-specific studies to address issues of concern such as water quality, water availability, and the interconnectedness of surface and ground waters.

Current Utah Streamflows and Lake Levels

Current Utah Streamflows and Lake Levels

Monitoring Utah's streamflows and lake levels has never been more important. Real-time data is key to resource management in a state with a growing population and rapidly-changing precipitation patterns.

Bear Lake Water Quality

Bear Lake, located approximately 50 kilometers (km) northeast of Logan, Utah, straddles the Utah-Idaho border and is nestled in a graben valley between the Bear Lake Plateau on the east and the Bear River Range on the west (Reheis and others, 2009). Its calcium carbonate type water is a brilliant green-blue color that, in combination with sandy beaches and easy access, draws thousands of...

Streamflow Information Program

The U.S. Geological Survey (USGS) operates and maintains a national network of about 8,000 streamgages (2018) to provide long-term, accurate, and unbiased streamflow information (often called discharge) to meet the multiple needs of many diverse users. Streamflow information is fundamental to national and local economic well-being, protection of life and property, and efficient and effective...

Lake Powell Coring

In response to the August 5, 2015, Gold King Mine Spill from the Bonita Peak Mining District that resulted in the release of three-million gallons of mine-impacted waters, the Utah Water Science Center, in partnership with the Utah Division of Water Quality, National Park Service, and U.S. Bureau of Reclamation, cored the San Juan and Colorado River deltas in multiple locations in Lake Powell...

Managed Aquifer Recharge

Sand Hollow Reservoir in Washington County, Utah, was completed in March 2002 and is operated for both surface-water storage and managed aquifer recharge via infiltration from surface basin spreading to the underlying Navajo Sandstone. From 2002 through 2014, about 216,000 acre-feet were diverted from the Virgin River to Sand Hollow Reservoir, and about 127,000 acre-feet of water seeped...

What is a streamgage?

Information on the flow of rivers and streams is a vital national asset that safeguuards lives, protects property, and ensures adequate water supplies for the future. The USGS operates a network of more than 9,000 streamgages nationwide with more than 150 in Utah, but how does a streamgage work? Dee Lurry of the Texas Water Science Center answers that question.
