Attachments: image001.jpg; Andy, Sounds good, the flows in the river drop gradually from now until September so we wont be caught off guard if flows drop off. I am sure we will have more discussions later in the month and we will talk about is some more ones the flows get below 100cfs im sure.

The flows this morning are 144 cfs so we have a bit to go.
