After suffering extensive damage from a storm in 2020, the spillway at Lake Lyman had to be demolished and replaced. Upgrades were added to the existing structure to enhance resilience and to provide a new slide gate and pedestrian bridge. Next, a new reinforced concrete flume spillway was constructed, including structural slabs, 20’ walls, an underdrain system, and vertical drains.
Concrete for the spillway flume was initially placed using a pump, and later a crane bucket was utilized to reach the required distance and depth of the project. Thomas Concrete used optimized mixes with THOMACOOL to meet the demanding specifications and control temperature.
