It took me 25 minutes to make a hole in 15 inches of ice due to dull blades on my auger.
So suffice to say I only was in the mood to make one hole.
Highest temp I could find about 100 feet from the diffuser was 34.5 F. in 9 feet of water the deepest spot in the pond. D.O. was between 12 and 13 ppm from 0 to 5 feet and between 11 and 12 ppm between 5 and 8 feet.
I blew more snow off the pond today but I think my life saver is my diffuser that is keeping water open. In fact judging by the low temps (below 39 F.) I'm thinking water is circulating from the diffuser throughout the pond evidenced by the low temps.
Do you concur Bill? Bill I actually dialed down the air about a week ago.
I'd like higher temps in the deep water but if it's a trade off I'll take the higher D.O. levels.
I hope this helps our understanding of what goes on in a hard winter with deep snow, thick ice, and the use of a diffuser.
Just got a report from an ice fisherman that in the large pond he fishes, the fish are just below the ice and concentrated near an inflow. Sounds like a winter kill is imminent there
