What this means today

At 210 cfs the Milwaukee River is 40 cfs short of the 250 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, 221 cfs to 210 cfs. Daily means over the past 7 days have run between 189 cfs and 275 cfs, 26% higher at the end of the week than the start.

Paddling Grafton to Cedarburg

Milwaukee River at Grafton to Cedarburg is a Class II run in Wisconsin — bouncy wave trains and the occasional small rapid. Most paddlers put in at Grafton (Lime Kiln Park area) and take out at Cedarburg area landing.

Whether it's worth the drive comes down to flow. This section generally paddles well at 250–700 cfs (a conservative estimate — see our methodology). Much below that and the Milwaukee 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 04086600 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.
