After nearly five years of waiting I'm thinking of throwing in the towel on my half acre pond. I have waited through the drought here in N.E. Oklahoma. I have waited for the dam to "settle in". I have dumped numerous hundred dollar bills (in the form of bentonite) into the water. I thought I did all the right things in constructing the pond dam, working with the local soil conservation office, hiring a reputable contractor, test holes, erosion control, etc... The dam just keeps seeping. All I have is a very small pond and a huge swamp! It has now become a question of $$$. I can have the pond filled in for less money than it will cost to attempt a drain and repair that may or may not work. It just goes to show that if mother nature wants something her way, she gets it!
