The Lake Clarendon Dam is a rock and earth-fill embankment dam with an un-gated spillway located off-stream in the locality of Lake Clarendon in the Lockyer Valley Region, South East Queensland, Australia. The main purpose of the dam is for irrigation of the Lockyer Valley.[2] [3] The resultant impounded reservoir is called Lake Clarendon.
Located northeast of, the Lake Clarendon Dam is part of a number of small dams built above the Lockyer Valley to supply water for irrigation purposes.
The 4200m (13,800feet) long rock and earthfill structure has a maximum height of 13.1m (43feet) and an overflow spillway which diverts excess water into a series of open channels that eventually flow into the Lockyer Creek. The dam creates a reservoir, Lake Clarendon, with a storage capacity of 24276ML and a maximum surface area of . The dam is managed by SEQ Water.
Completed in 1992, by mid-2006 the dam was empty due to drought conditions in Australia.[4] In January 2011, the dam was over 80% full according to the Queensland Water Commission website.
A Stocked Impoundment Permit is no longer required to fish in the reservoir. Lake Clarendon was removed from the SIP scheme in 2012.[5]
