Holland Lake

Available Water Storage Remaining

A weir at Holland Lake stores water so that it is available for use by the Town of Ladysmith and the Diamond area. Water is withdrawn through an intake at the weir and then delivered to these communities. The following graph shows the % available water storage remaining.

The available water storage calculation is based on 100% storage corresponding to the level of the spillway and 0% storage corresponding to the level of the water intake (the point of withdrawal). The Holland Lake Dam can actually store up to 0.6 meters above the spillway. However, water stored above the spillway is not released into the rivers at controlled rates and so it is not considered “available storage”.
