What this means today

At 3,460 cfs the Susquehanna River is inside the runnable range but only 2,260 cfs above the 1,200 cfs floor, so it is sitting at the shallow end of what this reach runs at. A dry few days would take it under.

Over the last 24 hours it has barely moved, 3,670 cfs to 3,460 cfs. Daily means over the past 7 days have run between 3,680 cfs and 5,910 cfs, 16% lower at the end of the week than the start.

Paddling Danville to Sunbury

Susquehanna River at Danville to Sunbury 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 Danville, PA access and take out at Sunbury / Northumberland, 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 1,200–25,000 cfs (a conservative estimate — see our methodology). Much below that and the 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 01540500 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.
