Valley Creek Dam Rehabilitation


Client: Williams Lake Indian Band

Date: Fall 2005

Value: $950,000



As a condition to the transfer of Federally held water licenses associated with Valley Creek to the Williams Lake Indian Band, INAC initiated and funded the rehabilitation of Valley Creek Dam in 2005.  Although classified as a rehabilitation project, the existing Valley Creek Dam structure comprised a long list of significant deficiencies.  As such, the dam essentially had to be completely reconstructed in order to meet the stringent requirements of the Provincial Dam Safety Regulation.



One interesting feature associated with this structure was the fact that it relied upon a diversion system from Borland Creek in order to store water.  The point of diversion at the creek was improved as a component to this project.  Because Borland Creek is a fish bearing watercourse, a diversion system was carefully designed which would allow water to be diverted from the creek to the dam during freshet conditions while both maintaining normal channel flow in Borland Creek and preventing the passage of fish from the Creek to the Dam.

Work associated with Valley Creek Dam included:

  • 310m long, 8500 cu.m. earth dam
  • 320m long rip rap lined high flow spillway system
  • 50m long low-level sluice pipe system with cast in place concrete control chamber
  • replacement of sluice pipe control works
  • 130m long outlet piping system
  • 450m long diversion piping system
  • cast in place concrete bridge crossing of the high flow spillway complete with integrated weir wall system

Valley Creek Dam provides storage of 60 acre-ft of water which is available for use by the Williams Lake Band for irrigation of hayfields located downstream of the structure.
