This study was conducted in the Shambley Creek research watershed (outlet location: 32.98410915, -88.01334337) on privately owned property in Greene County (AL, USA). The watershed drains a non-perennial unnamed tributary to Shambley Creek, and contains 0.70 km^2 of coniferous forest managed for silviculture in the East Gulf Coastal Plain physiographic section. Located near Eutaw, AL, the watershed spans an elevation range from 63 to 94 m above sea level, and is a tributary to the Sipsey River (within the larger Mobile-Tombigbee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 7.3°C and 27.4°C respectively, and mean annual precipitation of 1,350 mm/yr.

These data were collected in support of the sampling goals of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) Project. 14 pressure transducers were placed in seven sets of nested groundwater and surface water monitoring wells along the Shambley Creek watershed, as well as an additional pressure transducer hanging from a tree near WHM07 t to collect barometric pressure. These 15 pressure transducers collected data from Aug. 2021 through Sep. 2024, with the two pressure transducers at the watershed outlet being vented sensors (Seametrics PT12 pressure/temperature sensor) from 2021 through 2023, whereas all other sensors were unvented (Onset HOBO U20 series pressure transducers). These nested well locations monitored water level continuously throughout the project, as well as served as the AIMS approach 2 sampling locations, where a field team co-collected datasets characterizing the hydrology, biogeochemistry, and ecology across seven locations within the Talladega watershed six times across two years.

These sensors were set to collect temperature and pressure data every 15 minutes starting from Aug. 2021 through May 2024, and every 1 hour from May to Sep. 2024. The raw pressure data were converted to water level using barometric pressure data and surveyed elevation data. Each .csv file is associated with a single sensor for a single year.
