  1. CLASSIFICATION OF SIGNIFICANT WATER RESOURCES IN THE MVOTI TO UMZIMKULU WATER MANAGEMENT AREA (WMA) 3 October 2014 Presented by: Mmaphefo Thwala Technical Working Group Meeting

  2. STUDY PROCESS • In accordance with the classification, Reserve and RQOs guidelines 1 2 3 4 5 6 • Division of the Management Units (IUAs & RUs) & describing the Status Quo • Divided catchment into management units (IUAs) based on socio-economic/ • land use characteristics/ • water resources and defined Resource Units (RUs) • Data assessed • Status quo understood • Catchment vision established • Link value and condition of water resources • Assess the contribution of using water resources • Understand the importance and value of water in order to assess the implications and consequences of protecting water resources • Ecological requirements of water resources understood and quantified • Determine how much water does the ecology need for the protection of water resources • How much water does the ecology require for different protection levels • Identification and evaluation of scenarios • Scenarios are different options for protection within each catchment • Evaluated against flow, water quality and socio-economics • Determine the minimum level of protection • Recommended Management classes & RQOs • Setting requirements to satisfy the ecology • Setting requirements which the different users require from water resources Gazetting To gazette Classes, Reserve and RQOs We are here Stakeholder engagement

  3. THE PURPOSE OF THE TWG: SESSION 1 • To present additional technical information on the multi-criteria analysis approach to recommend Water Resource Classes • To evaluate and compare scenarios with the aim to find a balance between the level of protection and the use of water resources • Approach will be illustrated using the preliminary results of the Mvoti and Mkomazi river

  4. PURPOSE OF THE TWG: SESSION 2 • Gathering information for setting up river water quality RQOs • Obtain specialist stakeholder input with reference to: • Confirming the priority Resource Units for RQO determination • Identifying the priority indicator components (ecological and user water quality) to be addressed at each priority Resource Unit • Precursor to the derivation of RQOs for the priority Resource Units • Focus will be the Mvoti and Mkomazi river systems

  5. APPROACH OF THE TWG • Presentations of the methods • Description of scenarios • Demonstration of scenario assessment and ranking • Demonstration of how the Water Resource Class is derived • Interaction with stakeholders regarding site-specific information and supporting data sources

  6. EXPECTED OUTCOMES OF TWG • Understanding of methods • Input from stakeholders • Confirmed water quality hotspots • Confirmed primary users and key variables
