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 Wales, Australia.
The dam's primary role is to provide drinking water for the Tweed Valley 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.
Clarrie Hall Dam consists of an earth and rock embankment lined with concrete and with a concrete spillway, it cost $34,000,000 Au to build. The dam has a total storage capacity of 16,000 ML (13,000 acre·ft). The catchment area has an approximate area of 6,020 hectares (14,900 acres). The spillway level is 61.5 m above sea level.[1]

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.[2] Boat access for electric outboard and paddle-powered craft is available at Crams Farm, at the southern end of the waterbody. Lake Clarrie Hall has been stocked with more than 358,000 Australian bass fingerlings over the past 10 years. A NSW Fishing Licence is required to fish in the lake.
