Abstract: Gropps Lake Dam has a concrete ogee spillway with earthen abutments at either end of the spillway. The dam features an internal drainage system, outlet works, an energy dissipator, a steel sheet piling cutoff to the foundation, and a fishway. The solutions to problems related to sensitive-weak soils and relatively high horizontal permeability of the foundation; the integration of the fishway with the concrete ogee spillway; and the internal drainage system and cutoff represent the highlights of the project and the design improvements that enhance the economy, function, and safety of the structure. In addition, the introduction of a new design concept for the outlet works contributed to the innovative design solutions applied.
