What this means today

At 1,160 cfs the Iowa River is inside the runnable range but only 860 cfs above the 300 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, 1,210 cfs to 1,160 cfs. Daily means over the past 7 days have run between 1,220 cfs and 3,290 cfs, 63% 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.
