We put on at 5pm last night, 6 feet on the gauge. At that time, the flow below the wastewater treatment plant at Avon (the closest guage) was 2300cfs.
Here's the Avon gauge (http://waterdata.usgs.gov/co/nwis/uv...te_no=09067020)
As far as actual CFS in Dowd's I think the calculation is to take about 85% of that guage. Hope that helps.
