Paddling Fertile to Mason City
Winnebago River at Fertile to Mason City is a 13-mile Class I run in Iowa — easygoing moving water with light riffles and nothing technical. Most paddlers put in at Fertile and take out at Mason City, 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 100–1,500 cfs (a conservative estimate — see our methodology). Much below that and the Winnebago 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 05459500 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 May–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.
