There might be cold water algae blooms that die when snow cover and lack of wind occasionally eliminates sunlight penetration for long enough periods where decaying phytoplankton causes a large DO sag and a periodic winterkill occurs, but not regular annual winterkills. If the pond received good wind exposure the wind should be able to keep a significant portion of the ice blown free of snow.
Is this one of the ponds that Dr.Willis discussed in PB Mag where they were using windmills to minimize winter kill?
