The Logan River Basin occupies an area of 3435 sq km and extends from the McPherson Ranges in the south to Moreton Bay. The major tributaries are Burnett Creek and Teviot Brook. Peaks range from 49 m in the lower catchment to 448 m in the cenrtal part of the catchment to 1396 m in the Mc Pherson Range. The mean annual rainfall for the catchment for the 50 year period 1920-1969 varies from 1400mm in the south-west to 1800 mm in the south east and less than 900 mm in the central plains area. The major storage is Maroon Dam on Burnett Creek. Maroon Dam supplies water downstream to Cedar Grove, downstream from Beaudesert. This region is primarily cattle country. The Albert is a sub-catchment of the Logan River catchment. The Albert River flows into the Logan River 12 km upstream from where the Logan discharges into the Pacific Ocean south of Redland Bay. It is a long narrow catchment in which the major streams flow from south to north. The major storage is Beaudesert Weir with a storage capacity of 9130 ML. A significant portion of the catchment is used for dairy farming and is covered by quite lush pastures and open forest. In the upper reaches this open forest gives way to the dense rainforests of Lamington National Park.
The Logan-Albert River Basin (145) ARCE was moderately modified and the ARCB was in reference condition. The basin condition was largely unmodified based on the hydrological disturbance index, moderately modified based on the catchment disturbance index, largely unmodified based on the habitat index and substantially modified based on the nutrient and suspended load index.
The appropriate State agencies have reviewed this information and the following text is their comments and corrections.
The Queensland river condition workshop expert panel assessed the basin as falling in the lowest 10 of all the reviewed systems.
