yes. the evaporation of warm water takes the heat of the pond. covering it keeps the
heat in the pond along with the water. altho I do have a 500 watt heater in my pond
to keep the temp above 50oF for most of the winter (I am zone 5, to -20oF below zero)

covering seems to have
reversed that trend. I guess removing most of the wind chill has allowed
the residual heat in the ground to take effect.
