Drainage: ~317 sq.mi.

Drainage area at our listed put-in is approximately 317 sq.mi. (as calculated via USGS StreamStats Beta software). By our listed take-out, (with the confluence with the Elk River just upstream) it has increased to 615 square miles (94% increase).

As mentioned on the Flows tab, a USGS gauge exists many miles downriver (with drainage area of 1860 sq.mi.), where flow has been controlled by a number of dams. Thus that gauge is likely of very little value to estimate flows here.
