摘要

This report describes a project designed to derive an environmental flow regime forthe lower Coal River, southern Tasmania, downstream of Craigbourne Dam, and itsestuary and related coastal embayment, Pitt Water.Within the current Tasmanian water management policy context, the principle aim ofan environmental flow regime is to maintain existing values. This implies a focus onexisting conditions. However, opportunities for environmental rehabilitation/restoration should also be explored where they are broadly commensurate with theexisting water management focus, which in the lower Coal is on irrigation watersupply.The Coal catchment has been extensively cleared for grazing, and development forintensive agriculture has been stimulated by the development of irrigationinfrastructure. This development has had a number of consequences for the CoalRiver and Pitt Water, whose environmental condition is discussed in Sections 2-4 ofthis report.
