“In 2023, the project team completed the abutment excavation, hydro demolition of the dam face and a full-scale roller-compacted concrete test placement. We also nearly completed the foundation grouting and erection of the crusher and batch plants. In short, the preparatory work is almost complete, and the project is on track to start the dam raise in the spring of 2024.” - Jeff Martin, Denver Water Gross Reservoir Expansion Program Manager. 2023 Year in Review.
