This is Lock #7. The Hennepin Canal Parkway is a 66.3 mile east-west linear trail, and a 29.7 mile north-south "feeder canal." The mainline canal forms a segment of the northern route of the American Discovery Trail through Illinois. It also is part of the 500-mile Grand Illinois Trail. The eastern end of the Hennepin Canal at Bureau Junction is where the Hennepin connects with the Illinois River.
