The U.S. Geological Survey (USGS) Water Mission Area (WMA) - Ecosystems Mission Area (EMA) EcoDrought project is comprised of interdisciplinary teams across the United States focused on the nexus between drought and ecosystem processes. To characterize streamflow conditions in EcoDrought study areas, gage height (stage) and water temperature data were collected using submersible pressure transducers (PTs) in eleven small streams across the US. During various durations from 2019 to 2024, assorted configurations of vented (In-Situ TROLL® 700H) and unvented (Onset HOBO® U20L-04) submersible PTs were installed as “compact” streamgages with minimal infrastructure at thirteen sites in four states: 2 sites in Massachusetts (MA); 2 sites in Colorado (CO); 3 sites in Idaho (ID); 6 sites in Oregon (OR). Corresponding regional USGS Water Science Centers installed and operated the compact streamgages following USGS reference streamgage procedures (for example, hydraulically stable infrastructure and regular sensor check measurements and drift corrections; Sauer and Turnipseed, 2010). Additionally, the compact streamgages in MA, CO, and ID were collocated with existing USGS reference streamgages, permitting 1) the application of reference gage height-discharge rating models to compact gage height data to produce compact discharge data and 2) the comparison of compact and reference gage height (and discharge) data. This documentation describes a single CSV file containing the HOBO® absolute (water and barometric) pressure, water temperature, and barometric pressure data for USGS stations 423815118453900 (2020-06-17 to 2022-10-26; Donner Und Blitzen Above Indian Creek), 423830118453200 (2020-06-18 to 2022-10-25; Indian Creek NR Donner Und Blitzen Confluence), 424003118453700 (2019-07-24 to 2022-07-06; Little Blitzen River NR Riddle Ranch), 424325118495900 (2019-10-16 to 2022-07-07; Donner Und Blitzen Near Burnt Car Spring), 424547118503500 (2019-07-25 to 2022-10-24; Donner Und Blitzen Above Fish Creek), and 424551118503200 (2019-07-25 to 2022-10-23; Fish Creek at Donner Und Blitzen Confluence). These data are used to calculate sensor depth for each site, which is publicly available in Water Data for the Nation ([WDFN]; USGS, 2025).
