FOREWARD FOREWARD FFOORREEWWAARRDD The development of an Index of Stream Condition (ISC) allows. for the first time, a holistic assessment of the health of the rivers and streams in Victoria. The ISC has been developed as a new and innovative tool that can be usedbycatchment managersandthe communityin: - benchmarkingthe conditionofstreams; - assessing thelong termeffectiveness ofprogramstomaintainandrehabilitate streams; and - setting priorities totargetresources Use of the Index will lead to improved waterway management. better allocation of resources and genuine improvement in the condition of streams. The ISC will also assist Catchment Management Authorities with their statutoryreportingrequirements. The ISC was developed and trailed over a four-year period by a Specialist Reference Group (SUG)of scientific and industry experts.The initial development work included reviewing previous stream assessment methods ,and consulting with experts with knowledge of hydrology ,geomorphology,aquatic ecology, riparian vegetation and function ,waterquality,and rivermanagement policyandpractice. Following the development of the ISC concept,it was trailed in the field .Two catchments were chosen to represent different river systems :the Latrobe catchment in Gippsland and the Boken River catchment in north east Victoria.Results form the trails were discussed on site with the SRG and lessons incorporated into the ISC to make itmore reliableanduse friendly. The result is a monitoring tool that is based on scientific knowledge and principles. but which is user friendly. It is designed to provide a long-term summaryof all the majorenvironmentalattributes that affect streamhealth that can bemeasured atreasonable cost. I congratulate the SRG on striking a balance incorporating scientific information into the ISC and achieving somethinginnovative anduseful. This does not mean that the ISC can not be improved.
