Wallis Lake Estuary Management Plan 1 Introduction 1.1 Purpose of the Wallis Lake Estuary Management Plan The purpose of the Wallis Lake Estuary Management Plan (WLEMP) is to coordinate management efforts of local government, state government agencies and community to address issues regarding the social, cultural, environmental, recreational and commercial amenity of the Lake. The plan provides a schedule of achievable and targeted management actions that have been developed with and are endorsed by all stakeholders. The WLEMP has been developed in accordance with the State Government’s Estuary Management Program. It will operate in concert with a number of other policies including Ecologically Sustainable Development, the NSW Coastal Policy, the NSW Estuary Policy and other relevant local government policies (eg Development Control Plans). Local remedial plans and strategies for the estuary and catchment already in existence (see section 13.1) will not be replaced by the WLEMP. Instead the WLEMP will provide a strategic framework to ensure elements of these plans and strategies are implemented in concert with the broader management goals of the estuary community. The WLEMP will address management issues of the Wallis Lake water body and its tributaries up to the tidal limits, the foreshore and other lands adjacent to the estuary including wetlands and drainage reserves that are functionally related to the estuary. 1.2 Objectives The Wallis Lake Estuary Management Plan aims to provide a strategic framework within which management measures can operate effectively to: 1. conserve, protect and enhance areas of significant cultural, ecological and aesthetic value ∗ 2. restore or remediate degraded areas 3. balance the recreational, commercial, social and cultural needs of the estuary 4. increase the economic value of the estuary in an ecologically sustainable manner, and 5. increase community awareness of estuarine processes and management issues. 1.3 The estuary management process The Estuary Management Process (Figure 1.1) is outlined in the Estuary Management Manual (1992). This manual was developed to assist communities to implement the New South Wales Government’s Estuary Management Policy of 1987. The goal of this policy was for Estuary Management Plans to be developed and implemented for all estuaries in New South Wales. ∗ Aesthetic value is defined here is a combination of both water quality and scenic attributes. 1
