Project Name: Utica's Fall 2024 Maintenance Outage

Status: Complete

Description

During the outage, Utica will shut off water conveyed from the North Fork Stanislaus River that normally flows through Utica’s system from Avery to Angels Camp. During this period, water supply to UPUD and COA will be maintained using water stored in reservoirs. Throughout the outage, Utica will plan limited water deliveries to maintain the reservoir levels to meet operational needs and environmental requirements. On weekends in November, Utica may turn the water back on for a day or two in order to refill storage reservoirs.

While the system is de-watered, Utica staff will make needed repairs to our wooden flumes and gunite lined canals, which will help reduce water lost to leakage. While the Utica Conveyance Crew is working on flumes and canals, the Operations and Maintenance Crew will be making repairs and upgrades to both the Murphys and Angels Powerhouses. Below is a list of work anticipated to be completed :

Anticipated work in the Lower Utica System (P-2019) and Murphys Powerhouse:
• Maintenance and repairs to Flume 14
• Relining canal with shotcrete where needed
• Cleaning and patching canal where needed
• Vegetation control on upper and lower banks of the canal where needed
