West Branch Susquehanna — Williamsport to Montgomery: River Level Today — Can You Paddle It?

At 7,010 cfs the West Branch Susquehanna River is sitting in the middle of the 800 cfs–18,000 cfs range for this reach, with 6,210 cfs of margin to the nearer edge — the most forgiving part of the window on the numbers alone.

Over the last 24 hours it has gone from 9,590 cfs to 7,010 cfs, 27% down. Daily means over the past 7 days have run between 4,940 cfs and 13,200 cfs, 97% higher at the end of the week than the start. 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 — Williamsport to Montgomery is a 13-mile Flatwater float in Pennsylvania — no rapids under normal flows, just moving water and the odd riffle. Most paddlers put in at Williamsport, PA (Susquehanna State Park area) and take out at Montgomery, PA access, a trip that runs about 5 hours at a relaxed pace.

Whether it's worth the drive comes down to flow. This section generally paddles well at 800–18,000 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 01551500 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–October. 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.
