What this means today

At 971 cfs the Meramec River is inside the runnable range but only 771 cfs above the 200 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 gone from 1,080 cfs to 971 cfs, 10% down. Daily means over the past 7 days have run between 1,010 cfs and 1,810 cfs, ending roughly where it started.

Paddling Lower reach near Eureka

Meramec River at Lower reach near Eureka is a 8-mile Class I run in Missouri — easygoing moving water with light riffles and nothing technical. Most paddlers put in at Pacific/Route 66 area and take out at Eureka area, 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 200–5,000 cfs (a conservative estimate — see our methodology). Much below that and the Meramec 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 07019000 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.
