Thanks Dr. Luke! Just an interesting side note. I don't think we even have any 39 degree water left. On 11.05.17 the water temp was already down to 37.9 top to bottom! I would guess it's even colder now. I would love to get some current DO data! I have been looking at a DO logger than I can drop in the lake that will record the DO data a couple times per day all Winter. Would be very cool, but they aren't cheap!
