The Australian Centre for Tropical Freshwater Research (ACTFR) has been commissioned by the Department of Natural Resources (DNR) to provide an environmental evaluation of prospective dam sites located within the Burdekin Catchment. This exercise is a desk-top study based on existing data sources, with no original information being collected. Prospective dam sites that remain in consideration after this exercise will be subject to more thorough investigations at a later date. The purpose of this exercise is to raise issues that are currently known to exist
