What this means today

At 9.2 ft the Green River is 10.8 ft under the 20 ft ceiling for this reach. There is no published minimum here, so a low reading may still be too thin to float — the trend below is the better guide.

Over the last 24 hours it has barely moved, 9.2 ft to 9.2 ft. Daily average flow — a different measurement from the gauge height this reach is graded on — has run between 490 cfs and 890 cfs, 45% lower at the end of the week than the start.

Paddling Green River Ferry to Houchin Ferry

Green River at Green River Ferry to Houchin Ferry is a 12.4-mile Flatwater float in Kentucky — no rapids under normal flows, just moving water and the odd riffle. Most paddlers put in at Green River Ferry Access (Mammoth Cave NP) and take out at Houchin Ferry Access (Mammoth Cave NP), a trip that runs about 5 hours at a relaxed pace.

Whether it's worth the drive comes down to flow. This section generally paddles well at below 20 ft. Much below that and the Green 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 03309000 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.
