AIMS Johnston Draw Continuous Stage and Discharge at Watershed Outlet Data (AIMS_MW_JDR_DISC)

This resource contains high-frequency stage and discharge data collected at the outlet of the Johnston Draw watershed, including conductivity, dissolved oxygen, turbidity, fluorescent dissolved organic matter, and temperature. Johnston Draw is a 1.8 km² watershed in southwestern Idaho, USA (outlet location: 43.1226, -116.776) located within the Reynolds Creek Critical Zone Observatory in western Idaho, a research center with cattle grazing. Elevation ranges from approximately 1,490 to 1,850 m. The mean annual precipitation in the watershed is 550 mm/yr with rainfall occurring at the lower elevations and snowfall, resulting in large drifts, at the higher elevations (Godsey et al., 2018). Mean annual temperature ranges from 8.9°C at the bottom of the watershed to 4.7°C near the top. These data were collected in support of the core sampling goals of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) Project. Between March 2022 and October 2024, stage and discharge were monitored at the watershed outlet (GSS01) at 15-minute intervals.
