The Metropolitan Water District of Southern California will be undertaking comprehensive assessments of the spillways and dam structures at Lake Mathews and Lake Skinner along with preliminary design of upgrades to the dam monitoring systems at both lakes. The MWD board vote, Dec. 12, also approved an agreement with AECOM, an international design firm, for technical support of those activities. The $2.86 million appropriation for the project covers $2,000,000 for the study and $860,000 to upgrade the monitoring systems and includes $1.53 million for AECOM’s consultant work.
