Aspinall Unit Reservoir Operations
2012
Operational Considerations• Aspinall Unit Purposes
– Water storage / Compact Development– Power Production– Flood Control
• Downstream Flow Requirements - including Senior Water Rights, timing side-inflows
• Target Elevations• Meeting the ROD flow targets at Whitewater• Others - Including Recreation and Safety

Drought Rules During Dry and Moderately Dry years, if Blue Mesa Reservoir
content drops below 600,000 af, the Whitewater baseflow target is reduced from 1050 cfs to 900 cfs until Blue Mesa Reservoir content exceeds 600,000 af
Whitewater Baseflow Targets
2012 Spring Operational Goals
• Black Canyon Water Right• One Day Peak Target 814 cfs
• ROD Peak Flow at Whitewater• 900 cfs (1 days)
• <14,000 cfs at Delta, CO• Safe Ramping Rates• Fill Blue Mesa
