Document Description
The California Department of Fish and Wildlife (CDFW) has executed
Master Lake and Streambed Alteration Agreement EPIMS Notification Number COL-46998-R2,
pursuant to section 1602 of the Fish and Game Code to the project Applicant, Sites Project
Authority as represented by Alicia Forsythe.
The Project consists of the construction of a new off-stream surface water reservoir with a
capacity of approximately 1.3-1.5 million acre-feet. The Project will use existing infrastructures to
divert unappropriated flow from the Sacramento River at Red Bluff and Hamilton City and
convey the water to a new off-stream reservoir west of the community of Maxwell, California.
New and existing facilities will move water into and out of the reservoir, with ultimate release
back to the Sacramento River system via existing canals and a new pipeline located near
Dunnigan, California. The Project will require modifications to the Glenn-Colusa Irrigation District
system and the Tehama-Colusa Canal to move water into and out of the reservoir. Water
conveyance between Sites Reservoir and the canals and Dunnigan pipeline will be facilitated by
an existing and one new regulating reservoir and two new associated pumping/generating
plants. New electrical substations will connect the pumping/generating facilities and their
associated electrical switchyards to an existing overhead power line. Three new recreation
areas will also be constructed around the new Sites Reservoir. New roads will be constructed to
provide access to Project facilities and recreation areas, and some existing roads will be
relocated or improved. Construction of Sites Reservoir will also necessitate construction of a
bridge or bypass road to connect Maxwell with the community of Lodoga.
