Nontidal Water Quality Monitoring Stations in the Chesapeake Bay Watershed

Open the Data Source: https://gis.chesapeakebay.net/ags/rest/services/TMDL/non_tidal_stations/MapServer/2 Water quality monitoring data in the freshwater, or "nontidal," streams and rivers of the Chesapeake Bay watershed provide information on levels of nitrogen, phosphorus and sediment pollution, and how these levels have changed over time. Every two years, water quality monitoring data are analyzed to determine the amount of nutrients and sediment in streams and rivers, and to estimate trends in water quality conditions. This information allows planners, managers and implementers to assess progress and identify opportunities for restoration.打开数据源：https://gis.chesapeakebay.net/ags/rest/services/TMDL/non_tidal_stations/MapServer/2 切萨皮克湾流域（Chesapeake Bay Watershed）内的淡水（即“非潮汐”）溪流与河流的水质监测数据，可提供氮、磷与沉积物污染水平及其随时间的变化情况。相关机构每两年会对该类水质监测数据开展分析，以明确溪流与河流中的营养物及沉积物含量，并估算水质状况的变化趋势。此类信息可助力规划人员、管理者与项目实施者评估修复进展，并识别修复机遇。
