Burdekin River (below Dam) Wetlands

From Dry Tropics Wiki
Jump to: navigation, search


The flow regime, water quality and aquatic habitat of the Burdekin River below the dam has been highly modified by irrigation releases from the Burdekin Falls Dam, including persistently elevated water turbidity. This has had a major effect on ecological processes in a significant reach of the river, and although knowledge of the exact effects are limited, it appears to still be relatively healthy, just highly modified from natural. The reach also includes three weir pools, the most downstream of which, Clare Weir, restricts fish passage up the river, although a new fishway was installed there in 2006.
