My ice is just about gone. We have removed deicers although may have to put one back for tonight as it is supposed to go into the teens. Can't believe how yukkuy the bottom is. How can it get yukky when it is iced over all winter? Since the falls are still under 2' of snow we may put a pump in and run the hose to the bottom of the falls just to get the water circulating. It's plenty high with melted snow.
