San Joaquin Field Division Liner Raise and Instrumentation Project

The California Department of Water Resources (DWR) has released a draft Initial Study (IS) and intends to adopt a Mitigated Negative Declaration (MND) for the proposed San Joaquin Field Division Liner Raise and Instrumentation Project (proposed project). The draft IS and proposed MND have been prepared in accordance with the California Environmental Quality Act to provide agencies, the public, and interested parties an opportunity to review the environmental analysis for the proposed project.

The proposed project is located at Pools 24 and 25 of the California Aqueduct, specifically in Kings and Kern Counties between Aqueduct milepost (MP) 175.16 and MP 213.00. The northernmost site, MP 175.16, Pool 22, is approximately 2 miles southwest of the town of Kettleman City. The southernmost site, MP 213.00, Pool 25, is approximately 8 miles southwest of the town of Lost Hills.

Subsidence has caused reduced flow capacity in Pools 24 and 25 of the California Aqueduct that is limiting the ability to deliver water to Southern California. The proposed project would raise portions of the concrete liner on each side of Pools 24 and 25 over 1.65 miles and would also involve the installation of water level monitoring instrumentation to provide real time monitoring of flow and water levels in Pools 22 and 25.

The IS provides an assessment of the proposed project’s potential significant adverse impacts on the environment. The IS concludes the proposed project would not have any significant adverse effects on the environment after implementation of mitigation measures.
