Quick Facts

  • Since its creation in the fall of 2013, the Colliery Dam Technical Committee has spent the past eight months exploring remediation options for both the Lower and Middle Colliery Dams.
  • A key objective of the Technical Committee’s work included developing an environmentally, minimally invasive, cost and time-effective solution that addresses the safety of residents and businesses downstream of the dams and meets the requirements of the Provincial Dam Safety Regulations.
  • Golder has identified two remediation options, 1) enlarging the existing spillway from an average depth of 1.5m to 5m or; 2) modifying the dam by adding a hardened surface to protect the embankment below the dam in the event that water overtops the dam during a severe storm.
