Actually, there are no ice ‘dams’. The water is just slowly melting and standing pretty much everywhere enough for really sloppy conditions. Any slightly ‘low’ place in the yard/fields is particularly susceptible, but there’s nothing to be done to let it go somewhere else.
The nights are in the 20’s so the ground is freezing overall & water is not seeping in very much. We have rain again tomorrow, then about 3 days with some ‘warmer’ weather - Wednesday should be a high of 64, which will give us all spring fever. The somewhat warmer days (upper 40’s, 50’s) should thaw the ground a bit & the water will have a place to seep in. Starting next Saturday, it looks like 4 days of rain, but at least it’s not winter mix - highs in the 50’s, lows in the 40’s.
Thanks for the advice - if I do run across any ice ‘dams’ in the future (winter is not ‘over’ yet ... sigh), I’ll have a good idea what to do!
