Carpenter’s Dam

Closed 23 Feb 2023

Opened 16 Feb 2023


Red Moon Property Holdings Pty Ltd and property lessee Altera Ltd propose to construct and operate Carpenter’s dam taking water from 4-mile brook.

The proposal is to construct a dam not exceeding 3,400,000 cubic metres in capacity which includes an automatic bypass system that allows at least 8, 000 kilolitres of water to bypass the dam with excess water returned to the original watercourse.

The proposal is in Beedelup, WA, approximately 20 kilometres Southwest of Manjimup, adjacent to the Greater Beedelup National Park.

Why your views matter

At this initial stage of the EIA process, comment is simply sought on whether or not the EPA should assess a proposal and, if so, what level of assessment is considered appropriate.

What happens next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The EPA's decisions on level of assessment are released each Monday on the EPA's website.
