Getting ready to collect sample number 378 at Green Riv blw Green Riv. Samples collected at regular intervals over a long period of time are critical for understanding current water-quality conditions and changes.

Recent warm weather has increased flow in the North Platte River to above average for the date at the streamgage at Northgate, CO (just upstream of the WY-CO stateline). Real-time data online at: http://ow.ly/vodL50zt6YO

With ice off the Wind River near Kinnear, we headed out to make a streamflow measurement in open water. Flows were a bit higher than average for the date (35 years of record) and can be found real-time at: http://ow.ly/eSXS50zcGLF

Capitalizing on nice spring weather to visit sites and make streamflow measurements. Dinwoody Creek above Lakes was right at the 52-year average.

As part of a long-term study with the National Park Service to evaluate water quality in the Great Plains, water-quality monitoring equipment was installed at a site on the Niobrara River in Agate Fossil Beds National Monument.

Blackrock Creek above Split Rock Creek is online and now measuring temperature! http://ow.ly/BE8B50z2xZt Still plenty of snow on Togwotee Pass and since solo trips (to comply with social distancing) take longer, hot drinks are critical.

The stage of Belle Fourche River near Moorcroft rose nearly 10 feet one Saturday due to ice jamming and back water, and was nearing NWS flood stage.

Hats off to the tireless efforts of WYDOT and county crews for all the plowing to get roads open so we can do our jobs.

Drilling holes to collect samples for water-quality analyses at Green River nr LaBarge was made extra challenging by a temperature of -10F. It takes a lot of planning and quick action to collect and process the sample before equipment and water freeze.

The stream at this site is free flowing under the ice, so the relation between stream stage and streamflow works like it does in the summer (or other non-ice months). Real-time flow and stage for Dinwoody Creek abv Lakes online: http://ow.ly/a0L850yr2Nb

Streamflow and water-quality data have been collected at Fivemile Creek near Shoshoni since the 1940s. All data available on line at: http://ow.ly/uraY50ylvIi

It took all of the auger flight plus a little to get through ice to the creek. Collecting sample no. 238 from Muddy Ck nr Shoshoni. Monthly samples create a data set that can be used to describe water quality during different seasons and over time.

Instantaneous streamflow and real-time stage for Laramie River at Laramie, Wyoming.

Equipment is dropped through the holes drilled in the ice on the Little Wind River near Riverton to measure streamflow.

Wildlife out in force in Yellowstone as streamgagers headed into streamgages on Firehole and Gibbon Rivers. The thermal activity of the area means that the Firehole River is almost always ice free.

Stream stage is still accurately measured by equip under ice, and fluctuates a fair amount due to ice damming and accumulation. Streamflow, however, during most of the winter is typically quite stable.
