Lake Broadwater is the only large, naturally-occurring freshwater lake on the Darling Downs and is an important refuge for waterbirds and other wildlife. The lake is popular for picnicking, walking and birdwatching at any time of year; as well as power-boating, skiing, canoeing and swimming when conditions are suitable.

Lake Broadwater, surrounded by cypress pine, eucalypt and brigalow open woodland, is a shallow lake which covers approximately 350ha of the 1,212ha conservation park. It is listed in the Directory of Important Wetlands in Australia and is an excellent example of a semi-permanent freshwater lake in an area where these are rare. The lake fills only after heavy rains and, when full, is up to 3—4m deep. It dries out periodically—sometimes for lengthy periods.

More than 230 species of birds have been recorded at the park. The number and variety are due primarily to the wide range of habitat types; from wetlands to vegetation representative of drier inland regions. It is a valuable breeding ground for waterfowl, including migratory species that have travelled long distances from other parts of Australia and the world.

The park preserves valuable remnants of the vegetation types which once covered the Western Downs before European settlement. Many are now uncommon elsewhere due to agricultural development. Four hundred and fifty species of plants have been identified in the park, along with at least 30 mammals, 55 reptiles, 22 frogs, numerous fish and a myriad of invertebrates.

With easy access to water, tracks and recreational facilities, Lake Broadwater is a great spot to relax and to appreciate nature.
