Construction Time-lapse

Building a New Reservoir

Throughout the duration of construction on Chimney Hollow Reservoir we posted weekly images of the construction progress. Our camera was nestled up high on the ridge above Chimney Hollow and captured the action and changes as we built a new reservoir. Chimney Hollow Dam is a rockfill structure with a hydraulic asphaltic concrete core approximately 350 feet tall. The main dam contains approximately 12 million cubic yards of rockfill and 75,000 cubic yards of asphaltic concrete. Rockfill and aggregates were sourced from within the reservoir footprint. A two-row grout curtain and consolidation grouting was required for foundation preparation.
