Hafren Dyfrdwy Raw Water Storage - Reservoir Levels 2023

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.本数据集提供了关乎公共供水安全的水库原水储存水位实测数据。本数据集收录的水库均为筑坝拦蓄未经处理原水的天然水体。 本数据集不得用于决策供水限制措施的启用或解除（例如实施或取消软管用水禁令），相关用水调整事宜请等候所属供水商的官方指引。 若结合季节或近期天气情况来看，水库水位出现显著偏高或偏低的情形，可能属于正常预期范畴。 本数据集并未免除为保障洞穴探险/探洞安全而开展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：库容既可指代水库的可用蓄水容积，也可指代水库可容纳的总容积，其中包含地下水位以下的水体。
