The Friends of the Pecatonica River Foundation mission is to preserve, protect, and foster the vitality of the Pecatonica River for the plant, animal and human communities within the Stephenson County, Illinois watershed.
The Pecatonica River enters Illinois at Stephenson County north of Winslow. The name is believed to be Native American for crooked stream. The Pecatonica River is 58 miles long in Stephenson County and 94 miles in Illinois. The river joins the Rock River at Macktown, near Rockton. The early years saw roads develop all over the county. Many of the roads connected the mills that were in use in the county. Crossing the Pecatonica resulted in several ferries operating in the county. Toll bridges replaced the ferries and would be replaced with public owned bridges. The railroad was a significant influence for the area.
