Lake Abert, Oregon is one of the 20 terminal lakes identified by USGS partners as priority ecosystems for study by the Saline Lakes Ecosystems IWAA.

USGS Water and Fire Technicians team members, Jorge Gonzalez and Efren Alvarado, made repairs to the Buck Mountain precipitation gage during the Blue 2 Fire near Alto, New Mexico on June 7, 2024. This station, along with similar gages, provides critical real-time rainfall data to the National Weather Service and local emergency managers.
