River Raisin — Heritage Water Trail: River Level Today — Can You Paddle It?

At 139 cfs the River Raisin is 161 cfs short of the 300 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 gone from 128 cfs to 139 cfs, 9% up. Daily means over the past 7 days have run between 135 cfs and 182 cfs, 26% lower at the end of the week than the start. The last day and the week as a whole point opposite ways, which usually means a recent rain bump on top of a longer falling trend — worth a second look at the chart before you commit to the drive.

River Raisin at Heritage Water Trail is a 8-mile Class I run in Michigan — easygoing moving water with light riffles and nothing technical. Most paddlers put in at Dundee area access and take out at Monroe (Heritage Trail landing), a trip that runs about 4 hours at a relaxed pace.

Whether it's worth the drive comes down to flow. This section generally paddles well at 300–4,000 cfs (a conservative estimate — see our methodology). Much below that and the River Raisin 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 04176500 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.
