The basin upstream of the dam has a gross drainage area of 450 km2 and an effective drainage area of 372 km2. The components of the project include a 1040m long earthfill embankment, a 20m wide earthcut spillway around the west abutment, a low level outlet located near the west abutment of the embankment (West LLO) and a low level outlet located near the east abutment of the embankment (East LLO). The downstream water users include the Herbert and Rush Lake Irrigation Projects.

The work for this contract includes the provision of professional services to complete the final design, and construction oversight for the rehabilitation of the West Low Level Outlet. This includes general and specialized services during construction, project management services, environmental services and documentation as noted in this statement of work. Design and construction engineering for the remainder of the rehabilitation of the Highfield Project is not included in the scope of this service contract; these activities will be handled by a separate service contract.
