Calculating Pond Size
| Determining Surface Acreage of Rectangular Ponds |
The surface acreage equals the length in feet, times the width in feet, divided by 43,560. You can usually regard an irregular shaped pond as a rectangle or square and compute the area from straight boundary lines, which are about equal to your actual shoreline.
| If Your Pond is Circular |
Measure the total distance in feet around the outer edge of your pond. Multiply this number by itself, and then divide by 547,390. Your answer will equal the surface area of your pond.
