  Construction research 2026-10-24: McCook Stage 2 is In Progress: MWRD’s^[4] August 15, 2025 release explicitly describes active quarry excavation and a December 31, 2032 operational estimate. The native date is retained with estimated confidence; Stage 1’s 2017 operation does not complete Stage 2. The current TARP budgets mix shared Stages 1/2 works, mining and individual future preparation contracts. Neither the whole-reservoir budget nor a mining-change-order ceiling establishes a separately quoted all-in Stage 2 total. Source quote: “Stages 1 and 2” McCook budget includes combined stages and multiple separate contracts; not an all-in Stage 2-only budget.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
