Brennan started work in late 2020 on the Sandy Lake Dam located on the outlet of the Big Sandy Lake in northern Minnesota. Sandy Lake Dam is owned by the United States Army Corps of Engineers (USACE), St. Paul District.
The USACE identified that the original concrete structure needed repairs and improvements to address immediate safety concerns. Because the dam structure was more than 100 years old, the USACE used this as an opportunity to have Brennan rehabilitate the dam and update many of its operational features.
Our Work:
- Cofferdam installation and dewatering
- Demolition of the existing structure
- Concrete placement
- Sluice gate replacement
Our work on the Sandy Lake Dam Rehabilitation project concluded with a final concrete placement on August 29, 2022, and site demobilization shortly after. Thank you to the entire crew, our project partners, and our suppliers for working with us on this project.
