AIMS Talladega Continuous Discharge at Watershed Outlet Data (AIMS_SE_TAL_DISC)

This study was conducted in the Talladega research watershed (outlet location: 33.76219799, -85.59550775) in the Talladega National Forest (Cleburne County, AL, USA). The watershed drains a non-perennial unnamed tributary of Pendergrass Creek, and contains 0.92 km^2 of mixed coniferous and deciduous forest in the Piedmont Upland physiographic section. Located near Anniston, AL, the watershed spans an elevation range from 345 to 456 m above sea level and is a tributary to the Coosa River (within the larger Mobile-Tombigbee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 5.3°C and 25.3°C respectively, and mean annual precipitation of 1,400 mm/yr.

These data were collected in support of the core sampling goals of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) Project. Between 24 August 2021 and 15 October 2024, we monitored surface water level at the outlet (TLM01) of the AIMS Talladega watershed at 15 minute intervals using a pressure transducer (Seametrics PT12 vented pressure/temperature sensor from 24 August 2021 to 31 December 2022 and Onset HOBO U20 series unvented sensor from 1 January 2023 to 15 October 2024). Over the study period, we collected field measurements of discharge (in liters per second) during maintenance visits every three weeks at the watershed outlet. We then used these field discharge estimates with corresponding water level measurements from the continuous record to generate a discharge-stage rating curve and estimate continuous discharge.
