Columbia River Reservoir System Analysis: Phase II.

Abstract : Report documenting the application of the HEC-Prescriptive Reservoir Model for evaluation of three operation scenarios of the Columbia River system. The evaluation was performed to optimize the operation of: (1) existing policy with existing Canadian Treaty; (2) hydropower objectives were omitted; and (3) additional Canadian water is provided by Mica Reservoir. Conclusions include: HEC-PRM analysis performed successfully for the Columbia River System; three alternatives specified by CENPD were evaluated and compared; penalty functions were successfully used; using more storage at Mica does not significantly improve system performance; omitting the hydropower objective enhances system fish protection, navigation and recreation at the expense of system hydropower.
