If you have electric at the pond and a smallish sump pump, just let the pond water exchange into the barrels...only takes 15-20 minutes per barrel. You could be sorting/confirming while barrels are acclimating and tempering.
A 1000 watt power inverter will operate a 1/2hp sump pump if no electric pond-side....
