Features of the WCA contract include:

• Placement of zoned earthfill dam embankment.

• Manufacturing highly engineered sand and gravel filter and drain materials.

• Dam foundation treatment.

• Concrete lining of the outlet works tunnel.

• Construction of a control house at the outlet end of the tunnel.

Work is set to be completed in 2008.
