its about the same give or take a foot. when it does rise, it slowly goes away down to about where it is now, which is probably 4-5 ft. i got the backhoe out and dug as deep as i could with the extend a hoe at that spot i marked about 20 ft long down the front top of the dam, and when i came up with nothing, i then went to where the leak is and did the same thing. still nothing. even more amazing is the dirt down past 8 ft deep or so is all dry as a bone all the way down far as i can go. seems if there was a leak the dirt would be wet if i was anywhere close. since im already in there i maight as well cut from one end till the other and see if i can find water anywhere.
