What this means today

At 90 cfs the Tioughnioga River is 10 cfs short of the 100 cfs this reach needs to float — that is the gap between today's reading and the bottom of the runnable range, not a small margin you can paddle through.

Over the last 24 hours it has barely moved, 93 cfs to 90 cfs. Daily means over the past 6 days have run between 89 cfs and 99 cfs, ending roughly where it started.

Paddling Cortland to Marathon

Tioughnioga River at Cortland to Marathon is a 10-mile Class I run in New York — easygoing moving water with light riffles and nothing technical. Most paddlers put in at Cortland (river access) and take out at Marathon, a trip that runs about 4.5 hours at a relaxed pace.

Whether it's worth the drive comes down to flow. This section generally paddles well at 100–2,500 cfs (a conservative estimate — see our methodology). Much below that and the Tioughnioga 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 01509000 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–September. 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.
