California WaterFix Draft Supplemental EIR/EIS Available for Public Review and Comment

The Zone 7 Board of Directors would like to encourage the public to review and comment on the Draft Supplemental Environmental Impact Report/ Environmental Impact Statement (EIR/EIS) for California WaterFix. The Draft Supplemental EIR/EIS was released on July 17, 2018 and comments are being accepted through 5:00 p.m. PST on September 17, 2018. The document is available at www.CaliforniaWaterFix.com. Comments can be submitted by mail to "WaterFix Comments 2018," P.O. Box 1919, Sacramento, CA 95812 or by email to WaterFixComments@icf.com with the subject line "Draft Supplemental EIR/EIS Comments." 

The Draft Supplemental EIR/EIS evaluates proposed modifications to the project that was approved by the California Department of Water Resources in July, 2017. The proposed modifications would only affect the project footprint, and operations of the approved project would not change. Consistent with the approved project, water would be diverted from the Sacramento River through three fish-screened intakes on the east bank of the Sacramento River between Clarksburg and Courtland and conveyed by tunnels to a new forebay in the south Delta. Diversion facilities would also be identical to the approved project, with Intakes 2, 3, and 5 operating with a maximum capacity of 3,000 cubic feet per second each.

In September, 2017, the Zone 7 Board of Directors adopted a resolution to support California WaterFix. California WaterFix would provide a much-needed upgrade to the aging through-Delta conveyance currently used by Zone 7 to import roughly 80 percent of the Valley's supplies. Despite Zone 7's efforts to increase supply reliability through other sources, the Water Supply Evalution shows that Zone 7 will continue to rely on water conveyed through the Delta and delivered to the Valley via the SWP for about 70 percent of its supplies.

2018 Flood Control Channel Maintenance

Zone 7's flood control channels experienced a historic amount of damage due to the winter storms of 2017. This summer the flood protection program is embarking on efforts to repair a large portion of the damages. Progress and any impacts to publicly accessible maintenance roads can be viewed on this map.

Major Capital Project Updates

Zone 7 implements capital improvement projects to continue providing a reliable supply of high quality water, flood protection, and groundwater basin management. Click on the links below to obtain more information about the major projects in progress:

South Chain of Lakes Study

Starting on April 30, 2018, Zone 7 and the quarry operator, CEMEX, are collaborating on a groundwater study near the intersection of Isabel and Vineyard Avenues at Lakes A and B of the future Chain of Lakes facility. The study will include drilling into the ground near the lakes to collect data on aquifer conditions and soil characteristics. Drilling activities are not expected to impact traffic or trail access, as the drill rig will be within the perimeter of the mining area. The study is expected to last about a month.
