What this means today

At 3,840 cfs the Wisconsin River is inside the runnable range but only 1,840 cfs above the 2,000 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, 4,050 cfs to 3,840 cfs. Daily means over the past 7 days have run between 4,050 cfs and 4,450 cfs, ending roughly where it started.

Paddling Lower Wisconsin — Sauk City to Spring Green

Wisconsin River at Lower Wisconsin — Sauk City to Spring Green is a 19-mile Class I run in Wisconsin — easygoing moving water with light riffles and nothing technical. Most paddlers put in at Sauk City / Prairie du Sac landing and take out at Spring Green landing, a trip that runs about 7 hours at a relaxed pace.

Whether it's worth the drive comes down to flow. This section generally paddles well at 2,000–20,000 cfs (a conservative estimate — see our methodology). Much below that and the Wisconsin 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 05407000 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–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.
