Weather reports are predicting 3 consecutive days of sub freezing
temperature with drops into the single digits. We usually don't get that
cold so I have some concerns about my pond water becoming super chilled.
Last time this happened I draped a large plastic trap over the pond to
try and hold in some warmth. It seemed to work. I've left up the
bird/leave netting for the GBH so it will be a simple thing to toss the
tarp over the board supports for that.

Anyone else do anything out of the ordinary when the temperature gets
this low?

TIA.
