Pond Size And Depth. by Tom Burton. Once the where is decided, we need to determine size and depth. An ideal pond for the average hobbyist is between 23 and 25 feet long by 12 to 13 feet wide and 3 to 4 feet deep.
Preparing for a Farm Pond. Look for some basic features to turn an existing farm pond into a fish pond. The pond should be at least 1 acre in size. Smaller ponds can work, but pose some difficulties in managing the fish population. Fish ponds should be at least 6 feet deep, but no more than 12 to 15 feet deep. The water level should have a mechanism of control, such as a sleeved standpipe fitted with a cut-off valve at the bottom. The pipe and cut-off valve control water levels by allowing you to remove lower, unoxygenated water.
