Any chance the pond "turned over" due to the bitter cold and caused a severe low oxygen event?
This shouldn't be bad on only a 2 year-old pond? If it did occur, would it impact the LMB more than the BG?
Would feed on the bottom that was not consumed during late fall/winter contribute to an anoxic event?
Did you aerate the pond throughout the winter?
