I've used a circulator for 12 years to keep my "U" shaped dock open. I've always been amazed at what a great job it does keeping ice from building up on both docks .
This year....not so much.

I check my camera several time's/week and so far the circulator has only kept approx 10x10' area open in between the docks. the docks themselves are encased in ice. I feel it's due to the extremely low water level and colder than usual temps. As you may know, circulators basically work by circulating warmer water from the bottom to the surface. It may be that water temps at depth are not that much warmer because of the lower lake levels. (My own opinion/explanation)

The circ is on a timer and runs every day from 5pm-7am.
