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.
When deciding whether or not a given flow rate will. adequately supply a house, we first consider the depth of the well. A typical well holds about 1.5 gallons of water per foot and. will fill up to within 25 feet of ground level. At a depth of 300 feet the flow rate can be significantly lower than the depth of 100.
