They say a large cottonwood tree will drain 100 gallons of water a day in the middle of summer in kansas. Your pond mite be on a rock ledge and leaking. did you have any big trees die? when trees die the roots leave places for the water to leak. Muskrats will make holes which usually end damaging the damn. which usually washes out after time. does the pond ever fill up all the way? how deep would it be if it is full?
