We just started in on our one acre pond build. Right now we are stripping topsoil and prepping the site. It will be an excavated pond (i.e. no dam) and constructed in some of Indiana's finest clay. The test hole we dug in March has held water very well. It will be dug to a depth of roughly 20ft and most of the dirt will be used to create a massive berm on our property. It will be stocked and will also have a beach area. I plan to have a solar powered aerator in it as well. That said, anyone out there have any pointers/advice/lessons learned that they would be willing to share? Open to input on the construction, maintenance, fish structure, stocking, etc. Thanks all!
