WWDH Reservoir Conditions

This resource contains daily statistical summaries of reservoir storage conditions for reservoirs in the Reclamation Information Sharing Environment (RISE) network. Data is generated daily by querying the Western Water Data Hub (WWDH) API's Environmental Data Retrieval (EDR) endpoint for the rise-edr collection. Each daily file includes current storage values along with statistical benchmarks (percentiles, mean, standard deviation) calculated from historical data (1990-10-01 to 2020-09-30).本资源涵盖垦务局信息共享环境（Reclamation Information Sharing Environment, RISE）网络内各水库的每日蓄水状况统计摘要。该数据集每日通过调用西部水数据中心（Western Water Data Hub, WWDH）应用程序接口（API）的环境数据检索（Environmental Data Retrieval, EDR）端点，获取rise-edr数据集的相关数据后生成。每份每日数据文件均包含当前蓄水数值，以及基于1990年10月1日至2020年9月30日的历史数据计算得到的统计基准值（含百分位数、均值与标准差）。
