The Connolly Dam, also called the Silverwood Dam, is a rock–fill embankment dam with an un–gated spillway across the Rosenthall Creek and the Fitz Creek that is located in the Darling Downs region of Queensland, Australia. The main purpose of the dam is for potable water supply of the Southern Downs Region.
Location and features
The dam is located in a pristine mountain valley 15 kilometres (9.3 mi) southeast of Warwick and approximately 20 kilometres (12 mi) north of the Border Rivers region that generally defines the border between Queensland and New South Wales.
Completed in 1927, the rock–fill dam structure is 22 metres (72 ft) high and 145 metres (476 ft) long. The 115-thousand-cubic-metre (4.1×106 cu ft) dam wall holds back the 2,592-megalitre (0.570×109 imp gal; 0.685×109 US gal) reservoir when at full capacity. The uncontrolled un-gated spillway has a discharge capacity of 710 cubic metres per second (25,000 cu ft/s). The dam is managed by the Southern Downs Region Council.
Recreational activities
Golden Perch, Silver Perch, Murray Cod, Spangled perch and Eel-Tailed Catfish may be found in the reservoir. Golden Perch dominate most catches for lure/fly anglers, while Silver Perch and Eel-Tailed Catfish (dewfish) are more of a bait fishing prospect. A stocked impoundment permit is required to fish in the dam.
Connolly Dam is an "electric only" impoundment (outboards must be taken off) meaning only electric or manually powered craft may be used. Only members of the Warwick District Recreational Fish Stocking Association (WDRFSA) may take craft on the waterway, and only on weekends between sunrise and sunset. WDRFSA memberships are available from the caretaker at the dam currently costing $10. There is no boat ramp but there are many ideal locations around the dam to launch a boat. Membership cards must be shown to the caretaker prior to launching watercraft.
Camping is not permitted at Connolly Dam. Toilets are provided at the lookout adjacent to dam wall.
