We have several old human-made ponds on our Osage County farm. All hold water for part of the year, a couple of the ponds hold water year round; all leak considerably. Since water is a valuable resource in our part of Kansas, where the rural water supply is maxed out and a potable well needs to go down about 300 feet, we decided to invest in renovating at least two of our ponds. The first is our largest. It was formed by damming the deepest, steepest draw on the property around 40 years ago.
Since that pond has been surrounded by grassland for its entire life, it isn’t silted in too badly so our pond renovation won’t include dredging. This pond (Kate calls it draw pond) has maintained a level about 3 feet below the top of its drain pipe for the past couple of years. We determined that at least part of the problem relates to the corrugated drain pipe’s rotting away below ground … inside the dam. The other issue relates to the 30-year-old trees growing on the dam’s downstream face. Roots penetrate the dam and provide channels for seepage.
Since renovating this pond required moving a lot of dirt and trees, we hired a professional for the job. Pond renovation such as this requires heavy equipment in the form of bulldozers and track loaders … machines that weigh in the vicinity of 55,000 to 60,000 pounds each. They don’t come cheap, but they get the work done incredibly quickly, so the overall expense isn’t bad. And since it takes some effort to get the machines to your place, it doesn’t hurt to have several pond renovation projects on tap.
If you have ponds that need renovating, be sure to shop around for a knowledgeable excavator. We learned that the reason our other ponds leak is because they weren’t built correctly. I will write more on that after we get this pond renovation completed.
