Lake Catani is an artificial lake in the Mount Buffalo National Park in Victoria, Australia. It was constructed in 1910 under the supervision and probably design of the Victorian Public Works engineer, Carlo Catani, to provide recreational facilities in the newly opened winter resort. Carlo Catani was appointed Public Works Engineer in 1882, and spent much of his career developing hydrological schemes such as the drainage of Koo Wee Rup and Elwood Swamps.
