• 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
![Page 8: Overarching Strategy For the Sabie and Crocodile River Systems.](https://reader036.fdocuments.us/reader036/viewer/2022062802/56649e915503460f94b965a6/html5/thumbnails/8.jpg)
• 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

• 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.

• 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 .

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

• 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.
