The Darwin River Dam is an embankment-type dam. It is ungated with no spillway regulation possible. The dam relies on the annual wet season to be replenished. Toward the end of this season, the dam sometimes overflows. Most years spilling occurs, and is considered normal. Depending on rainfall amounts, this overflow can last from days to weeks.
The water in this dam is considered to be one of the most pristine on Earth. In order to preserve this quality, the catchment and reservoir policy prohibits recreational use with substantial penalties imposed for trespassing. Also, there is no Cabomba, an aquatic weed genus that can affect water quality.
The dam was formally opened by William McMahon (Prime Minister at the time) on 29 June 1972. The cost of construction was $9 million.
