1 Overarching Strategy For the Sabie and Crocodile River Systems

2 Areas Included: –Nelspruit –White River –Karino Plaston –Nsikazi South –Matsulu Crocodile River Catchment

3 Water Balance For Crocodile River Without Interventions

4 Envisaged Intervention Expected Benefit million m 3 /a Expected Starting Date Time to Full Yield/ Saving (Y) WC/WDM4.420145 Groundwater development0.520141 IAP Removals4.4201416 Operating rules White River Dams 120141 Water Trading4.320145 Boschjeskop (or other) Dam19.520185 Intervention Options For Crocodile River Catchment

5 Water Balance For Crocodile River With Interventions – No Dam Resource Groundwater IAPs Operating Rules

6 Water Balance For Crocodile River With Interventions & Dam Resource Groundwater IAPs Operating Rules Boschjeskop Dam

7 Low growth water requirements scenario can be met A dam will be required to meet the high growth water requirements scenario. Dam could be upstream or downstream of MLM. If downstream, water swops between MLM and irrigators will be required. Effect on aquatic environment needs to be investigated if lower dam is chosen Conclusions For Crocodile River

8 The current IAP removal programme should be checked and if necessary, the focus areas should be changed and the programme accelerated. WC/WDM Plans and implementation strategy to be developed Groundwater can be developed to contribute in overcoming the short term water shortages Urgent Actions Required

9 Area of fallow irrigation lands with water entitlements with no or limited risks of farm workers losing jobs which can possibly be earmarked for water trading. The preferred dam option needs to be selected. Choice between Boschjekop, Mountain View and Strathmore Dams. Towards Final Strategy – Further Information Required

10 Areas Included: –Hazyview –Nsikazi North Sabie River Catchment

11 Water Balance Sabie River Catchment Without Interventions

12 Envisaged Intervention Expected Benefit million m 3 /a Expected Starting Date Time to Full Yield/ Saving (Y) WC/WDM (15%)0.920145 Groundwater development0.320141 Purchase irrigation entitlements4.320145 Intervention Options For Sabie River

13 Water Balance For Sabie River With Interventions Resource Groundwater Water Trading

14 WC/WDM and groundwater development will improve the situation but will not achieve the required water balance. To achieve the water balance, water trading needs to be considered. The area of fallow irrigation lands with water entitlements with no or limited risks of farm workers losing jobs which can possibly be earmarked for water trading, needs to be. Conclusions For Sabie River Catchment

15 Development of the WC/WDM plan and implementation strategy Borehole siting with latest technology DWA to develop a policy for water trading Urgent Actions Required

16 The area of fallow irrigation lands with water entitlements with no or limited risks of farm workers losing jobs which can possibly be earmarked for water trading. The environmental water requirements of the Sabie River if the Reserve is optimised. Towards Final Strategy – Further Information Required

17 Facilitated Discussion
