This study was conducted in the Paint Rock research watershed (outlet location: 34.96861724, -86.16501705) on privately owned property in Jackson County (AL, USA). The watershed drains a non-perennial unnamed tributary to Burks Creek, and contains 2.97 km^2 of deciduous forest in the Cumberland Plateau physiographic section. Located near Estillfork, AL, the watershed spans an elevation range from 211 to 550 m above sea level, and is a tributary to the Paint Rock River (within the larger Tennessee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 4.4°C and 25.4°C respectively, and mean annual precipitation of 1,390 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 27 July 2021 and 3 October 2024, we monitored surface water level at the outlet (PRM01) of the AIMS Talladega watershed at 15 minute intervals using a vented pressure transducer (Seametrics PT12 vented pressure/temperature sensor). 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.
