The last day and the week as a whole point opposite ways, which usually means a recent rain bump on top of a longer rising trend — worth a second look at the chart before you commit to the drive.

West Branch Susquehanna River at West Branch Susquehanna — Karthaus to Keating is a 27-mile Class II run in Pennsylvania — bouncy wave trains and the occasional small rapid. Most paddlers put in at Karthaus, PA access and take out at Keating, PA access, a trip that runs about 9 hours at a relaxed pace.

Whether it's worth the drive comes down to flow. This section generally paddles well at 600–12,000 cfs (a conservative estimate — see our methodology). Much below that and the West Branch Susquehanna River gets low and bony, so you end up scraping gravel and walking the shallows; well above the top of the range it turns fast, cold and pushy, which is a more serious day than most casual boaters want. We read USGS gauge 01542500 about every 30 minutes and compare the live number to that window, so the verdict at the top of this page reflects conditions right now rather than a monthly average.

Flows here are usually most dependable April–June. Spring can run high after rain or snowmelt, and late summer often drops too low to float well — but the gauge always beats the calendar, so check today's reading before you go.
