Cofferdams upstream and downstream of Sanford Dam have kept the area dry so crews could work on the primary spillway and low-level outlet (LLO). During this time, the Tittabawassee River was temporarily routed around the dam (labeled 1 in photo below) through the breach channel. ![]() This week, crews removed the cofferdams upstream and downstream of Sanford Dam so water can flow through the Sanford Dam low level outlet (labeled 2 in photo above). First, crews removed the downstream cofferdam stone (pictured right) then pulled sheet pile from the upstream cofferdam (pictured below). Water begins to flow through the low level outlet (pictured below, bottom left) when the lake's elevation reaches 612.50 feet above sea level. To understand how lake levels work and the purpose of the low level outlet, check out this short video. Next Steps for Sanford DamCrews will build a cofferdam, and I-wall around the breach channel so they can construct the auxiliary spillway and right embankment. The river will flow through the primary spillway and LLO for the duration of the project. The river/lake level will remain the same with fluctuations due to weather conditions. Once the cofferdam around the breach channel is complete, FLTF will suspend construction until legal issues are resolved and it can acquire financing.
