Cotter Dam

Nov 22, 2015

The original Cotter Dam, a concrete gravity dam, was completed in 1915 built to a height of 18.6m. It was raised from 1949 – 1951 to a height of 28.5m to accommodate a growing population. It served as Canberra’s primary water source until the 1960’s.

The dam was enlarged again between 2009 & 2013, this time by constructing a new 80 metre high roller compacted concrete dam wall approximately 100 meters downstream from the original dam wall. This new dam wall increased the holding capacity of the reservoir from 4GL to 78GL.

The enlarged Cotter Dam, completed in 2013, was built as part of a suite of projects to ensure the ACT has a secure water supply. The new dam allows us to better deal with future droughts without having to endure high level water restrictions.
