The dam's purpose includes hydro-power, irrigation, water supply, and conservation. The impounded reservoir is called Lake Toonumbar. Location and featuresCommenced in 1969 and completed in 1971, the Toonumbar Dam is a minor ungated dam, located approximately {{convert|30|km}} west of Kyogle and {{convert|55|km}} north-west of Casino. The dam was built by Citra Australia Limited on behalf of the New South Wales Department of Land and Water Conservation to conserve water, control flows, reduce flood risk and provide a reliable water supply in the region.[1][2][3] The dam wall constructed with {{convert|361|m3}} of rock fill with clay core is {{convert|44|m}} high and {{convert|483|m}} long. The maximum water depth is {{convert|34|m}} and at 100% capacity the dam wall holds back {{convert|11100|ML}} of water at {{convert|129.6|m}} AHD. The surface area of Lake Toonumbar is {{convert|320|ha}} and the catchment area is {{convert|9800|km2}}. The uncontrolled concrete chute spillway is capable of discharging {{convert|1700|m3/s}}.[1][2][3] RecreationThe reservoir, Lake Toonumbar, provides a location for freshwater sports fishing for the species Australian Bass. Boat access is available at Bells Bay and near the dam wall, combustion engine powered craft are permitted to use the dam as long as the 8 knot speed limit is kept to. FishingLake Toonumbar has been stocked regularly with Australian Bass and Eastern Cod (totally protected in NSW) fingerlings. It is also known as one of the best bass fisheries on the North Coast.[4] A NSW Fishing Licence is required to fish in the dam. See also{{portal|New South Wales}}
