Wessex Water Reservoir Levels 2021-2026

This dataset provides the measurements of raw water storage levels in reservoirs crucial for public water supply. The reservoirs included in this dataset are natural bodies of water that have been dammed to store untreated water. This dataset must not be used to determine the implementation of low supply or high supply measures such as hose pipe bans being put in place or removed. Please await guidance from your water supplier regarding any changes required to your usage of water. Particularly high or low reservoir levels may be considered normal or as expected given the season or recent weather. This dataset does not remove the requirement for visual checks on reservoir levels that are in place for caving/pot holing safety. Some water companies calculate the capacity of reservoirs differently than others. The capacity can mean the useable volume of the reservoir or the overall volume that can be held in the reservoir including water below the water table. For Wessex Water reservoir total capacity information is based on gross capacity of the reservoir. Current percentage full will be a percentage of this gross capacity. Level information is provided as meters below spillway. Where the water level is 0 m it is equal to the height of the spillway, which is equivalent to 100% of the total volume storage available.本数据集提供关乎公共供水安全的水库原水（raw water）存储水位实测数据。本数据集收录的水库均为筑坝拦截以储存原水的天然水体。本数据集不得用于判定限供、增供措施的实施或解除（如实施或取消水管用水禁令）。有关用水调整的具体指引，请务必咨询您的供水服务商。结合季节或近期天气状况，水库水位异常偏高或偏低可能属于正常或预期范围内的情形。本数据集并未免除针对洞穴探险/探洞（pot holing）安全所需的水库水位目视检查义务。部分水务公司对水库库容的计算标准存在差异。库容既可指水库的可用容积，也可指水库可容纳的总容积（含地下水位以下的水体）。对于Wessex Water旗下的水库，其总库容信息以水库毛库容（gross capacity）为计算基准。当前满库百分比为该毛库容的占比。水位信息以溢洪道（spillway）下方的米数标注。当水位为0米时，其高度等同于溢洪道高度，对应水库可用总库容的100%。
