What this means today

At 1,720 cfs the Iowa River is sitting in the middle of the 300 cfs–6,000 cfs range for this reach, with 1,420 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 barely moved, 1,740 cfs to 1,720 cfs. Daily means over the past 7 days have run between 1,730 cfs and 4,110 cfs, 58% lower at the end of the week than the start.

Paddling Coralville Dam to Iowa City

Iowa River at Coralville Dam to Iowa City is a 7-mile Flatwater float in Iowa — no rapids under normal flows, just moving water and the odd riffle. Most paddlers put in at Coralville Dam tailwater and take out at Iowa City, a trip that runs about 3 hours at a relaxed pace.

Whether it's worth the drive comes down to flow. This section generally paddles well at 300–6,000 cfs (a conservative estimate — see our methodology). Much below that and the Iowa 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 05454500 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.
