Metropolitan Water District of Southern California
Diamond Valley Lake Dam Monitoring System Upgrade
NOE - Notice of Exemption
Project will upgrade the existing dam monitoring system at Metropolitan's Diamond Valley Lake. The upgrade is needed to maintain Metropolitan's ability to continuously monitor the performance of the lake's three rock-fill dams and will include replacement of weir level sensors and strong motion accelerographs, robotic survey stations, and automated data acquisition system.
The proposed action involves the funding, design, and minor alterations, reconstruction or replacement of existing public facilities and the construction of minor appurtenant structures with negligible or no expansion of use and no possibility of significantly impacting the physical environment.
