It is, here is the USGS site we use, updates every 15 minutes I belive. This gauge is located about a quarter mile below the dam.
Not sure exactly how long it will run 3500, probably mid June before normal-ish. I could see us dropping to be 2800 or less to slowly step it down as we get closer to normal.
