  • PURPOSE of HYDROGRAPH:
  • Develop recommendations for operational hydrographs based on anticipated possible annual release volumes from Glen Canyon Dam consistent with Section 1802 of the Grand Canyon Protection Act.
  • The operational hydrographs are within the framework of the 1996 ROD and MLFF operation, consistent with balancing other resources, including power production, and recognize the variability of possible annual release volumes from Glen Canyon Dam under the 2007 Interim Guidelines.
  • HYDROGRAPH CONCEPT:
  • Apply sound science principles within the framework of adaptive management to adjust the timing of water deliveries to protect and restore flow-dependent resource conditions.
