235 acres of watershed in Ohio for a 2.5 acre pond is TOO MUCH!

Most of us worry about having too little water for our ponds. You have the opposite problem.

When you are removing fill from your pond, you might consider building a few berms to divert some of the surface runoff around your pond. If the topography allows, you should preferentially divert the water from the most frequently tilled land.

Another option is to add a settlement pond upstream of your main pond. You are going to have to utilize heavy equipment to accomplish your goals for the main pond. Once the pricey stuff is on site, adding another small pond should not add too much more to your total costs - and you will get a much longer productive life for your main pond.

Good luck on your project!
