Arrowsmith Dam

The Arrowsmith Dam, with a live storage volume of 9,000,000 m3, is used to regulate the flow in the Englishman River for release during the summer and fall to meet the domestic water demands in the service area. Approximately 50% of the live storage volume behind Arrowsmith Dam is provided for release of water during low natural river flows, to improve fisheries flow in the downstream reach of the Englishman River.
