Conditions right now
Typical float time by month
Typical flow is estimated by adding the typical flows of the gauges above this stretch, since no gauge measures it directly. Float times are continuous drifting at that flow. Flow by month has the full record.
| Month | Typical flow | Float time |
|---|---|---|
| January | 1,428 cfs | 4h 00m |
| February | 1,405 cfs | 4h 02m |
| March | 1,553 cfs | 3h 53m |
| April | 2,221 cfs | 3h 23m |
| May | 8,049 cfs | 2h 04m |
| June | 15,800 cfs | 1h 36m |
| July | 7,867 cfs | 2h 05m |
| August | 3,490 cfs | 2h 51m |
| September | 2,464 cfs | 3h 15m |

Where this flow number comes from
No USGS gauge measures the Yellowstone at this stretch. The nearest mainstem gauges are Livingston, well upstream, and Billings, downstream; the gauges that once covered this water at Springdale and Big Timber are both inactive. So the figure above is not a reading — it is the sum of the gauges upstream of here:
Checked against the Billings gauge, which sits below every tributary in that sum, over 153 days of last season: mean error +2.6%, typical spread 10%, worst case -23% to +22%. Because water speed rises with roughly the cube root of discharge, a 20% flow error moves the float time by about 7% — inside the range already shown above.

Measured along the NHDPlus flowline, not straight-line distance.
Shuttle
7.8 miles by road, about 10 minutes driving. The drive is 0.92x the river distance.
Gradient
This reach is close to typical for this river, which is why its drift time differs from another stretch of the same length.

- The estimate does not account for irrigation withdrawal, which in this stretch is substantial in midsummer and removes water the tributary gauges have already counted.
- The velocity curve behind this estimate was measured between Corwin Springs and Livingston. Whether it holds on a channel this far downstream is adjusted for by gradient but not yet confirmed by reported float times here.
