Little Elk Creek (Elk Creek/Lake Erie trib.) - 1.) Old State Road to Francis Road (PA)
The gauge is close by and should be quite accurate.
This rapid can be anything from a Class II to Class V+ depending on the level. Concrete Falls is directly underneath Francis Road. The river becomes constricted into a fake narrow channel, slides down a sloping drop with one big hole, then plunges into the whirlpool. This is a fun ride and the climax of the trip. You can't scout it except from the shuttle because the area upstream of the falls is posted. Metal grading exists on the concrete bed, but you will not see it nor will it be a problem. If it weren't for that, this spot would be the ideal place to use as a waterslide. Take out just below on the left side or continue into the Lower Gorge.
WARNING: Excersise extreme caution in high water. The whirlpool at the base of the falls creates a death trap at levels above 1.4 ft.
