Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Dam safety upgrades planned
Pacific Gas & Electric proposes to install a filter and buttress to mitigate seepage at Lower Blue Lake Dam, increase the dam height by 2 feet to mitigate earthquake effects, and repair a downstream monitoring weir and add it into the project boundary. The proposed construction work is described in the license amendment application and would occur between June and October 2026.
Reservoir drawdown for construction
To construct the proposed measures, the licensee would lower the reservoir by 23.7 feet or more for up to 5 months. The filing states this drawdown would occur during the proposed construction window between June and October 2026.
No change to power output or operating elevation
The application is a non-capacity license amendment and the licensee does not propose any changes to the reservoir operating elevation or to the project's power production. The filing is explicitly limited to non-capacity changes.
Public comment and intervention deadline
Anyone may submit comments, protests, or motions to intervene on this application, but all filings must be received by July 23, 2025. The Commission encourages use of its eFiling or eComment systems and provides contact information for assistance.
