Document Description
The proposed project would raise portions of the concrete liner of the California Aqueduct's Pools 17 and 18 between Milepost (MP) 128.4 and MP 135.6 to maintain functionality in Pools 17 and 18 to enable DWR to avoid future disruptions of water deliveries to the Public Water Agencies, thereby maintaining operational flexibility and improving safety and reliability. The existing concrete liner would be raised approximately 1 foot 9 inches over a total length of approximately 8.9 miles on both sides of Pools 17 and 18. Construction activities would be performed above the waterline and would not require dewatering of the Aqueduct. Work would include excavation and use of on-site borrow material, road drain rerouting, and the removal and reinstallation of guardrails, road delineators and other existing features. Construction is anticipated to begin in 2027 and conclude within nine months.
