PG&E Files a Long-Term Flow Regime Request Due to Restricted Storage Capacity to FERC

UPDATED FEBRUARY 2024: The drought variance will end when Lake Pillsbury storage exceeds 36,000 AF after October 1, 2024, or is superseded by another variance or license amendment. The
36,000 AF storage threshold would allow the reservoir to meet minimum flow
obligations, including a possible Blockwater release, through January 2025 if inflow
is extremely low in early winter:

UPDATED  OCTOBER 2023: From the PG&E 2024 Flow Variance Request: "...FERC requested PG&E to file an application to amend the license to leave the spillway gates open indefinitely. Currently, PG&E has initiated the internal process to prepare the license amendment." 

On July 31, 2023, PG&E filed a Long-Term Flow Regime Request Due to Restricted Storage Capacity to FERC, a copy of which can be found linked below. The long-term variance is very similar to the 2023 short term variance that FERC is currently reviewing, with added provisions for winter diversions.

On October 4, 2023, FERC responded, requesting further information on multiple points.
