Abstract/Summary The proposed Penrith Lakes Scheme which is located in western Sydney comprises a series of 12 lakes and parklands, covering an area approximately 2,000 hectares. The development is located beside the Nepean River, and flooding, flood impacts and emergency response planning are key issues for the development. It is proposed to control the flow of floodwaters through the lakes using various weirs. One of the proposed weirs in the northern portion of the Lakes Scheme (the Wildlife Lake Weir) controls both the inflow of water into the Wildlife Lake and also the outflow of water from the Lakes Scheme in large flood events. As a result, it has the unusual feature of flowing in two directions. As part of the detailed design of this weir, detailed analyses were undertaken of a number of options before the final weir configuration was adopted. Once the flood has receded the Wildlife Lake Flood Outlet Pipe will drain floodwaters trapped in the lake back into the Nepean River. Detailed analyses were undertaken of options to address a number of considerations before the final outlet pipe configuration was adopted. This paper overviews the hydraulic analysis and design of the weir, spillways and outlet pipe. The construction of the Wildlife Lake Weir and Flood Outlet Pipe have been recently completed
