Gross Reservoir Expansion Project

It takes a long time to build a dam 471 feet high. A lot of other preparatory work is required such as quarrying and preparing the existing dam and foundation for the new dam.

The first planned work supporting the project consists of geotechnical drilling (summer 2018) and exploratory work in the Osprey Point Quarry starting after the reservoir is closed to boating for the season in October 2018. Next up, starting as early as 2019, is site development work and road improvements to the roads accessing Gross Dam. Principally, Denver Water is evaluating improvements and/or traffic control options for the intersection at SH72 and Gross Dam Road, and to Gross Dam Road itself.

Denver Water is committed to working closely with residents to ensure safety and open communication throughout construction.
