Clarrie Hall Dam
Encyclopedia
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 16000 millilitre. The catchment area has an approximate area of 6020 hectares (14,875.7 acre). The spillway level is 61.5 m above sea level.
was primarily designed as "an off-creek" water storage facility and building commenced in 1974 and ended in 1982.
. 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.
Dam
A dam is a barrier that impounds water or underground streams. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees are used to manage or prevent water flow into specific land regions. Hydropower and pumped-storage hydroelectricity are...

Spillway
A spillway is a structure used to provide the controlled release of flows from a dam or levee into a downstream area, typically being the river that was dammed. In the UK they may be known as overflow channels. Spillways release floods so that the water does not overtop and damage or even destroy...
