No matter the season, groundwater science continues! In this March photo, Hydrologic Technician Jeremiah Pomerleau is making groundwater measurements and inspecting the USGS groundwater site monitoring equipment. Due to snowy terrain, Pomerleau used a utility terrain vehicle (UTV) to access the well, requiring a trek of about 15 miles from the main road.

Modern equipment currently in use at the South Fork of the Ogden River streamgage, to include; an electronic data logger, pressure transducer and GOES radio. This streamgage has been monitoring water levels and flow since March 21, 1921, making it one of 25 centennial gauges in Utah. The equipment used to collect data has changed significantly over the pas

The USGS Active Groundwater Level Network includes about 20,000 wells that have been measured by the USGS or USGS cooperators at least once within the past 13 months. The animation shows a daily snapshot of water-level statistics in the network for January 2021.
