J.Obst - great work on the sampling guys!  Water quality looks good, particularly D.O., which shows a highly oxygenated system.  As you would have noticed, the mouth remains closed and we (CMA) are currently considering the need for an Artificial Opening.  This data contributes to the decision process, so it's very important!  Thanks Jarred
