ADCP Bridge Measurement

An ADCP is used to measure streamflow from a bridge near Kelly, Wyoming. Even with smoke making the view hazy, the Tetons never fail to make measuring streamflow in the Gros Ventre a treat.

Lamar River Downstream View

This photo was taken within Yellowstone National Park and shows a cableway view of Lamar River near Tower Ranger Station. Less than half a mile downstream, the Lamar River flows into the more well-known Yellowstone River. When this photo was taken, flows were just a bit above average at the streamgage.

Dropping the Wire Weight

The wire weight was dropped from this bridge to measure the stream stage of the Blacks Fork River near Lyman, Wyoming. Even with an early start, it is a struggle to get work done before an afternoon storm rolls in.

Collecting Water-Quality Sample Using Bridge Crane, Bighorn River

Summer Interns learning about sampling at the Bighorn River near Worland, Wyoming. The team used the bridge crane and heavy sampler to get water while streamflow was about twice average for the date.

Growth of algae and other aquatic plants is greater in Fish Creek than in nearby rivers and streams, according to a new U.S. Geological Survey report. This excess algae is related to the influx of nutrients, orthophosphate and nitrate, to the stream from groundwater and can lead to various environmental issues.

The U.S. Geological Survey's Wyoming and Montana water science centers will merge in October, improving science capacity and capabilities by integrating scientists in the two centers and allowing them to share equipment and expertise.

The mere presence of wolves, previously shown to affect the behavior of elk in the greater Yellowstone ecosystem, is not potent enough to reduce the body condition and reproductive rates of female elk, according to new research published today.

The U.S. Geological Survey has released a new report detailing changes of groundwater levels in the High Plains Aquifer. The report presents water-level change data in the aquifer in two separate periods: from 1950–the time prior to significant groundwater irrigation development–to 2011, and 2009 to 2011.

YELLOWSTONE NATIONAL PARK, Wyo. -- A new sensor network installed in Yellowstone National Park this summer will provide scientists and the public near “real-time” data on what’s happening in one of the nation’s most active geyser basins.

LARAMIE, Wy. — Previous research has claimed that the reintroduction of wolves to Yellowstone National Park in 1995 is helping restore quaking aspen in risky areas where wolves prowl. But apparently elk hungry for winter food had a different idea.

Continued high flows in the upper North Platte River and its tributaries have resulted in the river reaching an all-time record at the USGS streamgage on the North Platte River above Seminoe Reservoir near Sinclair. The gage height of 11.6 feet reached on June 14, 2010 is 2.6 feet above the National Weather Service flood stage.
