The smallmouth rivers the Fish & Boat Commission manages, from the Susquehanna, Juniata and Delaware to the Allegheny and French Creek, with its Best Fishing Waters, bass lakes, access areas and water trails for floats.
Check before you fish. Access, stocking and regulations here come from Pennsylvania's own data and can be out of date. Posted signs and landowners' wishes come first, and private land needs permission. The rules that apply are in the Pennsylvania Fishing Summary, and you need a valid fishing license.

Public land is shoreline context; on the big rivers the water itself is open to fishing. Access sites are the agency's own.

Smallmouth and largemouth water are the warmwater fisheries the Commission's biologists define for each species, by stream section. Best Fishing Waters are the sections and lakes PFBC names as the best for the species. Each section in a river's details gives its ends, length and the rule that applies, linked to the Fishing Summary: for example, catch-and-release bass on parts of the Juniata and Susquehanna.
Lakes are mapped as one point near the middle. Access sites are PFBC access areas (ramps, shore fishing, parking) within reach of the water. Water trails (off at first; turn them on under Layers) are PFBC's mapped floats.
On the big rivers the water is open to fishing, but the banks often aren't: get in from an access area or public land, and respect posted land. There are no river gauges on this map yet; check the flow before a float.
