WOW I used to fish the river as a child in Cecil county Maryland. The river is much wider than it is in Lancaster. The big deal then was catching shad and herring. I lived close to the Conowingo Dam. We had smallies in the streams nearby but I have never recalled anyone catching smallies from the Susquehana in Maryland.

In Maryland the river is about 1/4 to 1/2 mile wide. FAST moving waters.
