thanks for the information. the water is coming in right below the old creek. i have put in a 10 inch pipe going under the dam and turned the old creek over to the new pipe to divert the water on top. about 40 foot of the lowest ground is when i started having water coming in. it was slow at first but when i started digging up about the last 12 foot of core is when the water started coming in hard. the thing i don't understand is it's coming in from the down hill side, not the up hill side towards the pond.
