About the dam

Clarrie Hall Dam is located on Doon Doon Creek - a tributary of the South Arm of the Tweed River, some 15 kilometres south-west of Murwillumbah. The dam has a catchment area of 60 square kilometres and a usable storage capacity of 15,000ML.

The primary function of the dam is to store drinking water for the Tweed. When required, water is released from the dam’s intake tower and flows down the Tweed River.

At Bray Park, it is drawn off and treated at a state-of-the-art treatment plant to ensure suitable drinking quality.

Dam safety

Tweed Shire Council, as the dam owner, is responsible for safety at Clarrie Hall Dam. Dams are regulated by NSW Dam Safety Committee under the guidance of the Australian National Committee on Large Dams and the Dam Safety Act 1978. Council regularly monitors and reports on the condition of the dam under these regulations.

Clarrie Hall dam is extremely safe structurally.

While the current spillway capacity is deemed sufficient to pass an extreme flood event, there is still a small risk of failure in the unlikely event of an earthquake or other catastrophic occurrence. Council has a Dam Safety Emergency Plan (3.34mB PDF). The plan shows who will be affected and sets out how Council will communicate information so the public is protected and those directly impacted are evacuated.

The plan is activated during floods when certain dam levels are reached, or immediately if other events occur. Council provides education to downstream residents so they know how the Dam Safety Emergency Plan is managed. Visit our Emergency Management for more information.

Public access and recreation

Normally, Clarrie Hall Dam is open to the public from 7.30am to 5.30pm (6.30pm during daylight savings) all year round. Access is via security gates at Crams Farm on Commissioners Creek Road.

Clarrie Hall DamClarrie Hall Dam is set among picturesque forest. While the primary function of the dam is to provide storage for Tweed's water supply, it also is a great area for picnics and barbecues, bush walking, sports fishing and bird watching.

Facilities at Clarrie Hall Dam include toilets, picnic areas and electric barbecues.

Crams Farm Reserve has an extensive area for recreation, toilet facilities and two large sheltered areas.

Please note, dogs and horses are NOT permitted at Crams Farm.
