Clarrie Hall Dam is a dam built across the Doon Doon Creek that creates the artificial Lake Clarrie Hall. The dam is located close to the small town of Uki, New South Walesmarker, Australia.

The dam's primary role is to provide drinking water for the Tweed Vally Shire, by releasing water downstream into Doon Doon Creek when levels of freshwater in the Tweed River fall below 95%, which occurs mostly in Winter and Spring. Otherwise the natural flows of the Tweed River provide 80% of the water needs of the shire.

Purpose

The dam was primarily designed as "an off-creek" water storage facility and building commenced in 1974 and ended in 1982.

  • Lake Clarrie Hall provides a location for freshwater sports fishing for the species Australian Bass. Boat access for electric outboard and paddle powered craft is available at Crams Farm, at the Southern end of the waterbody.


Fishing

A NSW Fishing Licence is required to fish in the dam.
