The Australian Alps contain Australia's only peaks exceeding 2000 m in elevation above sea level. The Alps are the only bioregion on the Australian mainland in which deep snow falls annually. The Alps comprise an area of 1232981 ha .
Feather Headwaters The Feather Headwaters are 3 watersheds totaling 3450 sqmi and which drain to Lake Oroville. The North Fork Feather Watershed is 1090 sqmi —including the West Branch drainage of about 282.5 sqmi . The East Branch North Fork Feather Watershed is 1010 sqmi , and the Middle Fork Feather Watershed is 1350 sqmi —including the South Fork drainage of about 132 sqmi . Headwaters drainage is impaired by the Palermo Canal at Oroville Dam, the Hendricks Canal at the West Branch Feather River, and the Miners Ranch Canal at the South Fork's Ponderosa Reservoir. Additionally, the Pacific Gas and Electric Company releases Upper Feather water into the Hyatt Generating-Pumping Plant for hydroelectric generation during daily peak demand.
