RDN Water Budget Project – Phase One:
Vancouver Island
Phase 1 of the Water Budget project will be used to identify areas of concern for further study (Phase 2). The main Phase 1 report provides an overview of the hydrogeology of the six RDN Water Regions on Vancouver Island, water budget methods and results.
The report is divided into 5 sections:
IntroductionIn addition to this report, the Agriculture Water Demand Model helps us better understand the amount of water required for agriculture, now and into the future.
Detailed technical graphs and maps are included in the Appendices and links – see PDF downloads marked .
Tips for non-technical readers:
- Improve your understanding with Water 101
- Move your mouse over coloured words for definitions and links to more info
