South West Water (SWB) Reservoir Levels

Some water companies calculate the capacity of reservoirs differently than others. The capacity can mean the usable volume of the reservoir or the overall volume that can be held in the reservoir including water below the water table. In this dataset: Percentage of Capacity is based on Net Storage (the usable volume of water between the reservoir’s minimum operating level and its maximum operating level). Current Level is reported in meters below Top Water Level (the maximum designed water level a reservoir can safely hold under normal operating conditions). 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 rainfall level. This dataset does not remove the requirement for visual checks on reservoir levels that are in place for caving/pot holing safety.部分水务企业对水库（reservoir）库容的计算方式存在差异。库容可指代水库的有效容积，亦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。 本数据集中的库容占比（Percentage of Capacity）基于净蓄水量（Net Storage）计算，即水库最低运行水位与最高运行水位之间的可用水体容积。 当前水位（Current Level）以距最高水位（Top Water Level）的米数进行上报，其中最高水位指水库在正常运行条件下可安全容纳的设计最高水位。 本数据集不得用于制定供水短缺或供水过剩相关应对措施，例如实施或解除水管禁令。 请务必等待所属水务供应商发布相关指引后，再调整自身用水行为。 结合季节因素或近期降雨量来看，水库水位出现显著偏高或偏低的情况，可能属于正常或预期范围内的状态。 本数据集并未免除为保障洞穴探险与坑洞探险安全而需执行的水库水位目视检查义务。
