This Technical Report outlines the environmental values and associated watering requirements for seven wetland sites (Lake Leaghur, Lake Meran, Little Lake Meran, Lake Yando, Little Lake Boort, McDonalds Swamp and Round Lake), three waterway sites on the Campaspe River (2/11 Outfall, Cahir’s Billabong and Somerville’s Billabong) and two waterway sites on the Loddon River (Nine Mile Creek and Pennyroyal Creek) with particular reference to: 1. both historical and current environmental values 2. defined ecological objectives and associated water requirements 3. the proposed overall wetland water regime 4. the assumptions, unknowns and gaps in knowledge (to inform the adaptive management framework section of the plans). This document has been developed using the format developed for the Johnson Swamp, Lake Elizabeth and Lake Murphy Technical Report (NCCMA 2009a). The information in this report will form a key component of the Environmental Watering Plans (EWPs) being developed for the Northern Victorian Irrigation Renewal Project (NVIRP). This information was sourced from a variety of reports, from targeted field inspections and from individual knowledge and expertise (in particular Rob O’Brien, Department of Primary Industries, Kerang). The document will be used as a background paper for the Environmental Watering Plan Wetland Workshop to be held in December 2009. Therefore, please note that this report is a working document and should be considered in this context. The information should not be quoted or used for any purpose without the express permission of the North Central CMA.
