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.本数据集包含采自约翰斯顿德劳（Johnston Draw）流域出水口的高频水位与流量监测数据，涵盖电导率（conductivity）、溶解氧（dissolved oxygen）、浊度（turbidity）、荧光溶解有机物（fluorescent dissolved organic matter）以及温度等指标。约翰斯顿德劳流域位于美国爱达荷州西南部，流域面积为1.8 km²，出水口地理坐标为43.1226, -116.776，隶属于爱达荷州西部的雷诺兹克里克临界带观测站（Reynolds Creek Critical Zone Observatory），该研究中心开展牛群放牧相关研究工作。流域内海拔范围约为1490至1850 m，年平均降水量为550 mm/年，其中低海拔区域以降雨为主，高海拔区域则以降雪为主且易形成深厚积雪（Godsey等，2018）。流域年平均气温从底部的8.9℃至顶部附近的4.7℃不等。本数据集的采集工作旨在支持“溪流微生物群水文间歇性影响（Aquatic Intermittency effects on Microbiomes in Streams, "AIMS"）”项目的核心采样目标。2022年3月至2024年10月期间，研究人员在该流域出水口GSS01以15分钟的时间间隔开展水位与流量监测工作。
