Cheat

I came on 4/1/09, the Albright gauge shows 0.5 when the real level was up-to 8'.

The Albright Gauge is wrong, don't use it, use the Parsons Gauge instead. By looking at the flow of the Parsons Gauge you can estimate the Albright Bridge Level:

Albright Bridge Level = 1.0 foot at ~ 1000 cfs
Albright Bridge Level = 3.0 feet at ~ 3100cfs
Albright Bridge Level = 5.0 feet at ~ 6000 cfs
Albright Bridge Level = 8.0 feet at ~ 11000 cfs
