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.
While in some spots the lake reaches a depth of 400 feet, extending 150 yards or more from the shore much of the lake is only 12 to 14 feet deep. A characteristic trait of long, narrow lakes with deep channels is the seiche. Both Loch Ness and Lake Champlain are endowed with this peculiar feature.
