Gross Reservoir Expansion Project
Progress and schedule
There are many steps to building a dam 471 feet high. Final dam design will continue into 2020 to meet our current completion date of 2025. A lot of other preparatory work is required such as quarrying and preparing the existing dam and foundation for the new dam.
Denver Water is committed to working closely with residents to ensure safety and open communication throughout construction.
