THE WAITAKERE RESERVOIR is situated on the Waitakere Stream, about 14 miles from Auckland. This, the first impounding reservoir constructed by the Council in connection with its gravitation scheme, has a storage capacity of 220 million gallons, and has yielded, with the dry weather flow of the stream, 3 million gallons as its minimum daily supply. The water area of the Reservoir is 64 acres, and the catchment area 2,200 acres. The overflow weir, which is 100 feet long, is situated 580 feet above sea-level and 50 feet above the bed of the stream. The dam is 540 feet in length, and is curved to a radius of 382 feet, measured to the upstream face. The width on the bottom is 231 feet, and at the top it is 3 feet 6 inches.
