Got into the pond today with temps in the mid 30's. There was a lot of debris in the pond from the very rough winter we had here in northern Ohio. The pond was froze over for 3 month and never unthawed besides the area around the pump. We had the 3rd coldest winter ever, and I am pleased to say our pond that is only 2 feet deep did very well. The ice thickest at the max was 9'' thick and we had plenty of days below zero. We lost one fish but I expected that because our pond was put in, in August so they didn't have much time to get settled in before the cold came rushing in. But the 2 bullfrog tad poles we put in survived as well! We are pretty excited to get this season going, hopefully by the end of the week the pond will be cleaned out and the waterfall will be up and running. Temperatures next weekend will be in the 50's, it can only get warmer from here on out! Has anyone else opened their pond for the spring?
