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.
Your pond needs sufficient depth so that in winter there is adequate oxygen in the water under the ice to keep the trout alive. In general, trout ponds in this area need about 8 feet of depth and a sufficient source of cold water (such as natural springs) to provide the conditions that trout need.
