Contract value

$12,000,000

No explicit dollar amount is disclosed. Based on the scope—full design of eight high‑capacity spillway gates, associated hoist and electrical systems, concrete rehabilitation, rip‑rap replacement, environmental permitting, and a five‑year construction‑management support component—a comparable dam‑gate replacement project in the Pacific Northwest typically ranges from $10 M to $15 M. Considering the optional construction‑management services and potential federal funding, a midpoint estimate of roughly $12 M is reasonable.
