South Lake Como Boating Site

The Lake Como Boat Launch Site is located within the Lake Como Recreation Area, located between Darby and Hamilton, Montana.  The site hosts 38 boat trailer parking spots and a 4-section floating dock.  The wider, longer dock and wide ramp allows for recreationists to safely and easily launch their watercraft from either side of the dock.  Depending on lake levels and weather conditions the boat dock is generally installed by late-May and removed by mid-August

Lake Como is an irrigation reservoir.  Water levels fluctuate throughout the year, with the lake typically being at its highest from spring through late-July. Lake Como plays a vital role in irrigation for the Bitterroot Valley. The lake serves as a late-season water source, storing water from Rock Creek and releasing it to the main canal that serves a 72-mile stretch of irrigation to the Valley.
