Georgetown Lake, at the upper reaches of Flint Creek, is one of the state’s oldest hydroelectric projects. The lake is incredibly popular with the locals and is visited summer and winter.
Flint Creek was first dammed in 1885 and was further developed in 1891 when the silver mines in Philipsburg  demanded a source of electric power. In the 1890s Marcus Daly’s Butte , Anaconda , and Pacific Railroad ran weekend trains to the lake for the workers in Butte and Anaconda. A steamboat plied the lake, offering excursion trips.
Today, the preferred pastimes at Georgetown Lake are boating, windsurfing, fishing, and snow-kiting, although many people simply go there to weekend at their cabins.
