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.
