The Construction of Chimney Hollow Dam: A Marvel of Engineering

TLDRThe Chimney Hollow reservoir project in Colorado is constructing the biggest new dam in the United States in the past 20 years. It will eventually stand 350 ft tall and hold 90,000 acre-feet of water. The dam is built using advanced engineering techniques and infrastructure, including an asphalt core and a spillway. The project also involves quarrying and on-site production of materials like asphalt and concrete. A tunnel will carry water from a valve house to the top of the reservoir.

Q&A

What is the Chimney Hollow reservoir project?

—The Chimney Hollow reservoir project is constructing the biggest new dam in the United States in the past 20 years. It will eventually stand 350 ft tall and hold 90,000 acre-feet of water.

What materials are being used to build the dam?

—The dam is being built using advanced engineering techniques and infrastructure, including an asphalt core and a spillway. Materials like asphalt and concrete are being produced on-site.

How is water being supplied to the reservoir?

—A tunnel is being constructed to carry water from a valve house to the top of the reservoir.

How much water will the reservoir hold?

—The reservoir will be able to hold 90,000 acre-feet of water.

What is the purpose of the spillway?

—The spillway is designed to prevent water from overflowing the dam and causing a catastrophic failure. It redirects excess water away from the dam.
