Pond is about 2 surface acres. I MAY be draining it for renovation (muck, leaks near top, drain pipe replacement) within the next 2 years. If there are advantages (or no disadvantages) to a stationary dock I could wait until water is drained to drive in some pressure treated posts (6x6's?) for dock supports. However, if there are potential problems I could avoid the wait and build a floating dock now.
