The WESP is a master planned conjunctive management project that would acquire rights to existing unappropriated surface waters in the Calaveras River, Rock and Littlejohns Creeks, and the Stanislaus River. The purpose of the project would be to apply these waters to direct (in-lieu) recharge of the Eastern San Joaquin Groundwater Basin.
The subject waters consist of flood releases and/or peak wet season flows. These waters would be taken under control at existing and new diversion facilities and conveyed by canals and pipelines to up to 7,000 acres of proposed recharge sites located in the vicinity of existing and proposed conveyance systems.
The project would allow a maximum diversion and use of up to 598,900 acre-feet annually. The project would involve the construction of an intake expansion and one new intake on the Calaveras River, the construction of a new six-mile canal, the lining of eight miles of an existing SEWD canal, construction of an approximately 20-mile extension of the existing Upper Farmington Canal, and approximately 25 miles of pipeline ranging from 30 to 120 inches in diameter.
