WHY - Red Gap Ranch?
Overdraft?
Drought?
• Water Conservation – decrease in per capita water use by ~40% since 1980s (186 116 GPCD)
• Still have Long-term impacts to groundwater supplies
• Need for a diversified water supply for existing residents here today - redundancy & drought protection
WATER MANAGEMENT DECISIONS
WHY - Red Gap Ranch?
• Due to multi-years of drought and impacts to Flagstaff’s water supplies
• In 2004, a $15 million Bond was approved
• Purpose to acquire and/or develop property or
water rights
Citizens approve Future Water Supply
