Finishing up water-quality sampling on Blacks Fork, the last field run of the summer for two of our interns.

Streamflow training at Blackrock Creek below Split Rock Creek near Moran, Wyoming. A new student intern learns how to measure streamflows upon arriving in Riverton just in time for high water.

Dragon’s Mouth in the Mud Volcano Area of Yellowstone National Park.

Measuring streamflow in Little Snake River near Dixon, Wyoming. Streamflows were quite a bit lower than the 75-year average.

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.

100 Spring Plain in Norris Geyser Basin, Yellowstone National Park.  The area is frequently flooded and impassable. Photo taken by Lauren Harrison in August 2018.

Sensor (left) and battery/electronics package (right) at vent location A in the Deep Hole area of Yellowstone Lake.  Photo was taken immediately before recovery from the lake floor. Notice the battery/electronics package slightly submerged in sediment.

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.

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.

An exciting ride to get the ADCP to the main channel on the other side of the willows for streamflow measurement at the Shoshone River near Lovell, Wyoming.

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.

River Styx, Mammoth Hot Springs, Yellowstone National Park. This thermal feature is actually a subterranean hot water creek that likely collects water discharged from Mammoth Hot Spring pools that, after cooling and outflowing from vents, tends to disappear back underground through the porous travertine.
