  • Water Deficit: Demand > Recharge
  • STRESS LEVEL LOW: <50% MOD: >50% HIGH: >100% Residential 37% increase Commercial increase Agricultural increase
  • How reliable are the stress assessments? Example: North Degnen Bay • Assumes ~85% of water use in North Degnen is agricultural • High agricultural demand April-Sept (irrigation period) • Agricultural demand values assume maximum licensed volume of water across the entire irrigation period • Low total demand/km2 compared to other sub-regions • % recharge assumed uniform year round North Degnen Bay
  • Water Budget Study: Conclusion Author recommendations:  Improved estimates of hydraulic parameters (pump tests)  Increased water level monitoring (Mudge & DeCourcy)  Monitoring of rainfall and water level rise  Increased monitoring of coastal wells for Saline intrusion  Water budget calculation parameters need improved accuracy (survey #s, commercial & agricultural use is unknown, surface water!)

Assess current state (i.e. poor, good, high)  WHAT  Conclusion 3. Watershed Management  What & Why  How & Who 6. Reasons for not achieving good status  WHY 7. Action plan to achieve good status/improve  HOW
  • PRESENTATION Integrated Watershed Management Planning 1. DWWP update  Program 1 WHO?  Program 2  Program 3 Residents  Program 4  Program 5 Industry  Program 6 Stewardship groups  Program 7 2. Water Budget  Background  Overview  Methodology  Findings  Conclusion 3. Watershed Management  What & Why  How & Who Scientists Conservation groups Government A key component to the success of these plans is public input…you live in the watershed! You know it best
  • Integrated Watershed Management Planning Where do we go from here? In your opinion: • what are the priority watershed issues? • who is responsible for watershed management? • what do you think the DWWP program should focus on?
