Its been cold out!!!! Hydrologic Technicians Tom Eaton and Crystal Hammer braving the cold weather to ensure the 402913084285400 Chickasaw Creek at St. Mary's OH streamgage is accurately measuring water level and flow.

Ice measurements are done to ensure we report accurate data during winter flows.

Stay warm!

Congrats to Dr. Tanja N. Williamson, research hydrologist - pedologist for the OKI WSC. Dr. Williamson had one of the top cited papers in the Journal of Environmental Quality! Read more below!

This paper in Journal of Environmental Quality (https://doi.org/10.1002/jeq2.20290) was just highlighted as being among one of ten most often cited. The analysis of water quality in a western Lake Erie headwater tributary showed that phosphorus (P) concentration significantly differed for total (T), dissolved (D), and normalized particulate (PSS) forms between events when maximum TP concentration coincided with maximum DP versus maximum suspended sediment (SS) concentrations. Analysis used data collected as part of GLRI-supported research at both edge-of-field and stream scales.

Hydrotech Tyler Sink conducted a discharge measurement from a kayak at site 03251900, Stoner Creek near Paris, KY (link: https://waterdata.usgs.gov/monitoring-location/03251900), recording a flow rate of 62.5 cubic feet per second.

This routine visit was essential for verifying gage height accuracy and maintaining the stage-discharge relationship.

Before and after! Spring rainstorms often lead to log jams, prompting hydrotechs to intervene and remove them.

Recently, at site 05536179 Hart Ditch in Dyer, IN (link: https://waterdata.usgs.gov/monitoring-location/05536179), a log jam was nearing the or***ce line and temperature sensor, causing an artificial increase in gage height. To ensure the accuracy of the stage-discharge relationship and data quality, the jam was cleared by our hard-working hydrotechs.

The Murray Field Office has been actively managing the high water levels on the Ohio River. Recently, a team conducted operations at site 03612600, located at Olmsted, IL, (link: https://waterdata.usgs.gov/monitoring-location/03612600), where they collected PFAS and other National Water Quality Network (NWQN) samples.

During this operation, they calibrated the water quality sonde and performed a discharge measurement, recording a total of nearly 600,000 cubic feet per second. To put it in perspective, that's equivalent to 600,000 basketballs floating past every single second! A huge shout-out to the dedicated Murray crew for their hard work!

Terrible omen, or friendly pollinator?

Either way, planting native flowers and plants will help you stay on Mothman's good side! (It can't hurt, right?)

By providing food and habitat, native plants can attract all manner of winged pollinators to your yard, including bees, butterflies, and moths*. Other ways to help include keeping leaves on the ground in the fall and avoiding the use of insecticides that are harmful to pollinators.

We can’t promise we won’t tell mothman if you don’t...

Patrick Mayo and Caleb Artz setting up sediment sampling tubes for Black Creek near Harlan, IN (https://waterdata.usgs.gov/monitoring-location/04183038) and a nearby tributary. These tubes collect an integrated sample of sediment transported by the stream after a rain event. Collecting samples for streams of different sizes helps us understand source, size, and age of sediment. This provides key information on how to limit nutrients and sediment that foster harmful algal blooms.
