Gauge is located under the GA53 bridge on river left.
The absolute minimum is .8 on the bridge and .08 on the online gauge although it would be a long abusive day to your boat.
A realistic minimum is 1.1 on the bridge and1.1 from the online gauge.
Online Gauge Information
I have found that the online gauge and the bridge gauge correlate quite well.
