There are quite a few costs that go into the creation of a farm pond, each of which will need to be factored separately. In general, excavation for ponds less than 20 acres ranges about $3,000 to $5,000 per acre. Most farm ponds will be in that size range, but larger ponds over 20 acres can be excavated for around $2,000 per acre.
You’ll also need to factor permit fees for local, state and federal permits, if any are applicable in your area. Your pond liner, if needed, can be another expense—and this can vary widely based on the size of the pond and the type of liner needed. Costs may also come from water sources to fill the pond, like digging a well or paying electric costs to run a well pump, and there may be some added expenses for your pond’s drainage needs, though depending on the drainage system, these can be small. Also be sure to check local fisheries and aquaculture suppliers for prices on fish, plants and other things you may add to the pond once complete.
