The Bill Gunn Dam is an earth-fill embankment dam with an un-gated spillway located off-stream in Laidley Heights in the South East region of Queensland, Australia. The main purpose of the dam is for irrigation of the Lockyer Valley.[1][2] The resultant reservoir is called Lake Dyer.

Location and features

Located Script error: No such module "convert". west of the town of Laidley, the dam was developed to increase the capacity of the existing Lake Dyer, a natural lake adjacent to Laidley Creek, a tributary of Lockyer Creek. The dam was named after the Queensland politician Bill Gunn and is managed by SEQ Water.[1]

Water from the dam is used for irrigation, in the densely cropped Lockyer Valley.[1] Bill Gunn Dam suffers from high drawdowns and summer evaporation which together with phosphate fertilizer creates significant blue green algae problems.[1] In November 2005, during drought conditions in the area, the dam's water level declined to just 1%.[3]

Recreation

A boating permit is not required, however a maximum of eight boats are allowed on the lake at once.[1] A single concrete boat ramp and some facilities for visitors, including campers, are available at a lakeside caravan park which is managed by the local council.

The dam is stocked with silver perch and golden perch, while bony bream, spangled perch and eel-tailed catfish breed naturally.[1] A Stocked Impoundment Permit is required to fish in the dam.[4] The poor water quality means that fish caught in the dam may, at times of an algae outbreak, be a health hazard if eaten.[1]
