It looks like it's running but I just wanted to check to see if there was anything wrong with the gauge or any extra info I should know. Would be a bummer to drive all that way to get shut down. Thanks for the info!

Youll likely have to walk in quite a ways, and it will be really low if not boatable at all. At this point in the season, I believe the Cle Elum puts in the majority of the water because the watershed for the Cle Elum is lower. The gauge is actually on the Cle Elum after the Cooper enters. Later in the season when the Cle Elum has gotten low and temps are warmer, then the Cooper is dumping in more water and the gauge settings on this site actually correlate to boatable flows.
