2015 High Flow Experiment Snapshot
The 2015 Fall HFE was canceled due to the discovery of green sunfish in Glen Canyon
Sediment Conditions
Fall Accounting Period
- Paria input (Jul 1 - Nov 8): 1,168,498
- Accumulated in Upper Marble Canyon (Jul 1 - Nov 8, lower bound) = 563,000
- Accumulated in Lower Marble Canyon (Jul 1 - Nov 8, lower bound) = 214,000
- Available for HFE: 563,000 + 214,000 = 777,000
- Paria input (Dec 1 to Apr 1): 32,000
- Evacuated from Upper Marble Canyon (Dec 1 to Apr 1, lower bound) = -517,000
- Accumulated in Lower Marble Canyon (Dec 1 to Apr 1, lower bound) = 37,000
- Available for spring HFE: -517,000 + 37,000 = -480,000
