1. Staff recommended against a one-time golden mussel treatment in 2026 Staff recommended against proceeding with a proposed one-time copper treatment for the Cross Valley Canal (CVC) in 2026, favoring development of a broader 2027 strategy. Several golden mussel subcommittee participants supported waiting; the advisory committee took no vote on treatment. The consultant’s proposed one-time treatment was estimated at $1.6 million to $3.8 million and would not be a permanent solution. Staff reported no new growth in areas already dewatered and cleaned, and said existing mussels are not hindering operations. Further assessment will inform a potential eradication treatment followed by lower-dose maintenance treatment. A 2027 budget item, a later supplemental cash call, and budgeting without immediate collection were discussed; no funding approach was selected.
