Work is now back underway on three of the four dams, including Sanford Dam. Construction on the Edenville Dam, which corresponds to Wixom Lake, is expected to restart in early July.

The task force said the Sanford Dam is expected to be completed in December, with construction expected to be done on the Smallwood Dam in June of 2026, and the Secord Dam in September of 2026.
