Donner Lk Nr Truckee Ca
Donner Lake is located near Truckee, California, and is a popular recreational area for swimming, fishing, and boating. The lake was named after the Donner party, a group of pioneers who became stranded in the area during the winter of 1846-1847. The hydrology of the area is influenced by the surrounding mountains, which feed snowmelt into the lake.
