Could anyone explain why the flow rate is different on the Genoa river stage page at: http://www.crh.noaa.gov/ahps2/hydrograph.php?wfo=arx&gage=genw3&view=1,1,1,1,1,1

versus the lansing page at:
http://www.crh.noaa.gov/ahps2/hydrograph.php?wfo=arx&gage=lnsi4&view=1,1,1,1,1,1

With the tailwaters of Genoa and Lansing being the same pool I am a little confused…. Much like fishing this last weekend.

Thanks

I have no idea other than one appears to be ft above sea level (I think) and the other unit is stages (flood stage)? Someone here should have an answer for you.
