North Temperate Lakes LTER: Groundwater Levels 1984 - current

Water levels in monitoring wells are measured several times throughout the year. The number of monitored wells has ranged over the study period from 19 to 44 wells. Currently, 37 wells are being monitored 4 - 5 times per year. The wells are scattered throughout the Trout Lake hydrological basin and the data are used to calibrate and test regional groundwater flow models. In addition (see related data set - Groundwater Chemistry), water chemistry is measured annually in a subset of 11 of these wells to characterize regional groundwater chemistry in the Trout Lake area. Sampling Frequency: varies - generally from 4 - 9 times a year Number of sites: 44

监测井（monitoring wells）的水位在全年内会被多次测量。本研究周期内，监测井的数量在19至44口范围内波动。当前共有37口监测井，每年接受4至5次监测。这些监测井分散分布于特劳特湖（Trout Lake）水文流域内，所采集的数据用于校准与验证区域地下水流模型。此外，为表征特劳特湖区域的地下水化学特征，研究团队会从上述监测井中选取11口作为子样本，每年对其开展一次水化学检测（详见相关数据集——地下水化学（Groundwater Chemistry））。本数据集采样频率存在差异，通常为每年4至9次，监测站点总数为44个。
