Umgeni Water embarked on a process to develop a Resource Management Plan (RMP) for NAGLE Dam, which is the first RMP to be developed for any of the dams owned by this organisation.

4 Nemai Consulting (RMP Process Facilitator) was appointed by Umgeni Water (RMP Process Initiator) to compile the RMP for NAGLE Dam. The phases of the RMP development process for NAGLE Dam are presented in the diagram to follow. Phases of the RMP Development Process for NAGLE Dam Focus of this document NAGLE DAM RMP RMP (Draft) November 2016 ii This document presents the RMP, which is the culmination of the overall process, and integrates the information contained in the other deliverables to develop a sustainable plan for the use and management of NAGLE Dam. An overview of the dam, its operational requirements, infrastructure components and facilities is provided. The main pieces of environmental and development-related legislation governing the use and management of NAGLE Dam and the surrounding land are also presented, together with the management functions of key Government Departments.

5 The RMP also includes a brief description of the following, based on information extracted from the preceding deliverables: Biophysical and socio-economic environment, as detailed in the Research Report; Hindrances associated with the potential utilisation of the dam and its shoreline area for recreational purposes, based on the findings of the Encumbrance Survey; and Desired state and objectives for the future management of NAGLE Dam, as established as part of the Vision and Objectives Report. This information set the scene for the future management requirements for NAGLE Dam, which are provided in the following sections of the RMP: An Institutional Plan, which consists of a three-tiered management system that includes a RMP Steering Committee, Operational Management Committee and Dam Management Committee; A Zonal Plan, which considered The water surface of the Dam; The shoreline area, which includes the remainder of the NAGLE Dam property; A Strategic Plan, which takes into consideration the management objectives related to NAGLE Dam, based on the outcomes of the RMP deliverables.

6 And A Financial Plan, which provides information on how revenue generated through recreational use should be used, as applicable. Based on the priority management requirements identified for NAGLE Dam, various Business Plans will be developed which will be captured in the final RMP deliverable. The Business Plans will summarise the operational and financial objectives of the RMP and will contain the interventions, resources and timeframes required to achieve these objectives. This RMP will be reviewed every 5 years and revised as necessary, according to changing priorities, constraints and achievements. The Business Plans will be updated annually.
