Tender Details

Detailed_Description : The Madawanson Lake Dam is a rock-filled timber crib structure constructed in 1968, located approximately 59 km north of Highway 17 at Massey Ontario. A Ministry of Natural Resources (MNR) access road branches east from Highway 810, which provides the sole vehicular access route to the dam site.The dam consists of a 58.22 m long by 4.57 m wide rock-filled timber crib, with a 4.27 m span stop log controlled bay near the centre of the structure.
