1. Introduction and Purpose
• Existing County Water Supplies
• Growing Water Demands-> 2035, 2050
• Strategy to Meet Demands
• Planning Options
• 5 Alternatives -> 3 for FurtherStudy
2. Water Supplies
Colorado’s Water Plan (By 2050):• 500,000 AF Water Supply Gap
• 400,000 AF Met by Efficiency, Reuse
PLANNING HAS BEGUN!
2. Water Supplies
Acre-Foot (AF)
2. Water Supplies
Colorado’s Divide• 80% population on East Slope
• 80% water on West Slope
2. Water Supplies
Elbert County Groundwater• Creeks
• Alluvial Water
• Denver Basin Aquifers
• Designated Basins
2. Water Supplies
Water Use In Colorado• >60% leaves state• Remaining: 5.3 MAF:
• 89% Agricultural use

5. Planning Strategies
• Denver Basin Groundwater
Preservation
Drought Supply
• Renewable Water Supplies
Mixture Of Options
A. Reliance on GroundwaterContinue development of Denver Basin aquifersNo water sources pursued
6. Water Supply Options
B. Purchase and Import Renewable Water
Purchase Junior Water Rights – S. Platte River System
Increased Competition
