Current construction activities
Current work activities:
Denver Water and its contractor, Kiewit Barnard, are placing concrete to raise Gross Dam. Learn more about this process on our raising a dam - RCC webpage. Placing concrete to raise Gross Dam includes:
- Crusher plant operations: The crusher plant is located near the quarry. The crusher plant produces the rock, gravel and sand needed for the dam raise. This reduces truck traffic coming to the site.
- Batch plant operation: The batch plant will take materials produced at the crusher plant (rock, gravel and sand), and mix them with cement, fly ash and water from the reservoir to create the concrete for the dam raise.
- Quarry development: Rock is excavated from the on-site quarry and brought to the crusher plant where it is turned into aggregate and sand for the RCC. Blast notifications are provided via email and on the project MyMap.
Upcoming work activities:
- Tree removal: Denver Water submitted an agency-reviewed amendment to the 2021 Tree Removal Plan for FERC approval. The amendment eliminates haul roads west of the Gross Reservoir Expansion Project site, refines helicopter use and landing locations and reflects all tree processing on the eastern portion of the site. Parts of the 2021 Tree Removal Plan, such as scope and objectives, project description and environmental compliance, have not been changed. This is a draft document until FERC approves it.
