December 18, 2020 - 7.D. Review of Interim Guidelines

CONCLUSION
  • The most useful graphic from the Final EIS of 2007 Interim Guidelines. Lake Mead scenarios that seriously challenge hydropower operations: Colorado River System Simulation (CRSS); baseline data is the hydrologic record of the 20th century; three traces juxtaposed with the 10th, 50th and 90th percentiles, under No Action Alternative (business-as-usual) and to Year 2060. Here is the Lake Powell graphic which indicate a range of scenarios from serious challenges for flood control to curtailments of hydropower. A system failure will eventually happen long before sediment fill compromises water storage and flood control. The management of the hydrologic extremes is the imperative for dam operations, not the statistical norm. Until full adaptation to this imperative is accomplished, the system will be compromised. Interim guidelines is scheduled to be replaced before December 31, 2025. If the replacement document is more of the same, the Reclamation Era ends and its place in history will be bookmarked as an unsuccessful social experiment.
