Drainage: 1800 sq.mi.

Drainage area at the listed put-in for this section is 1800 square miles (as calculated by USGS Streamstats V4.3.11).

USGS gauge for 'Flambeau near Bruce' lists drainage area of 1860 square miles. (Interestingly, Streamstats comes up with drainage at that location as 1890 square miles, about a 1.6% difference.)

Actual flow at the put-in *could be* (on average) about 95% the flow on the gauge.

(Divide gauge flow by 20, then subtract that from gauge reading).

We have not bothered to create a virtual gauge because there are three dams between this section of river and the gauge location. (The relatively minor difference in drainage area is generally not as consequential as the regulation by the dams is likely to be.)
