Cressbrook Dam is one of the three water storages used to supply Toowoomba and the surrounding region. The dam was constructed in 1983^[1] for the former Toowoomba City Council, now part of Toowoomba Regional Council. The other two storages used for Toowoomba are Perseverance Dam and Cooby Dam.

Cressbrook Dam has a surface area of 517^[1] hectares with a total capacity of 81,842 mega-litres when full (78,847 ML usable) at an average depth of 15.8 meters. The catchment also contains Perseverance Dam, which is located 10 km upstream of Cressbrook.

Fishing

A Stocked Impoundment Permit is required to fish in the dam^[2].

Current Water Levels

Due to several years of below average rainfall the usable storage capacity of Cressbrook Dam is currently 27.9%^[3] or 22,022 ML capacity (as of 14 October 2010) and as a result Toowoomba is under high level water restrictions.
