Market: Water Resources; Irrigation
Completion: Current Project (Started 2016)
Project Narrative: The Huntley Project Irrigation District provides essential water delivery to the agriculture community and other users in Yellowstone County. Tunnel 2 is located at the head of the irrigation system and is 1,600 feet long, 15 feet wide, and 20 feet tall. If Tunnel 2 were to fail, water delivery would be cut off from 36,000 acres, leaving farmers high and dry during the critical growing season.
More on Tunnel 2:
- It was built in the 1930s.
- Modifications were made in the 1990s.
- The tunnel started experiencing failures and collapses following the 1990s modifications.
- Since last modification there has been a partial collapse of the tunnel, and the overall danger of the facility is increasing, which threatens the community.
- In 2016, a 12-year-old girl drowned in the tunnel, which re-emphasized the critical need for changes and modifications to the current design.
Project Result: The Tunnel 2 Remediation Project still in progress.
- Inspection and engineering review and analysis of existing conditions.
- Preliminary engineering report and alternatives for remediation.
- Preliminary designs on slip lining the tunnel, open cutting the tunnel
- Geotechnical review
- Coordination with U.S. bureau of Reclamation and the Montana Rail Link
- Presented at public meetings.
- Public/Community information campaign for project
- Managed funding applications the U.S. Bureau of Reclamation
- Completed funding application package
- Able to secure $1.2 million in grant funding assistance while negotiating a 3%, 30-year loan with the Montana Legislature (only to later be rejected by Governor Steve Bullock).
