Prairie Du Sac is located in Sauk County, northwest of Madison between Baraboo and Mount Horeb along Hwy 78 on the banks of the Wisconsin River near Merrimac, Lodi, Waunakee, and Mazomanie.
Eagle watching is a favorite pastime for many visitors to the Prairie du Sac area. The churning action at the base of the local dam keeps ice from forming on the surface of the water during winter, and this exposes the fish to hungry eagles.
