If you are pre construction phase remember two very important things
1. A double barrel sheepsfoot roller or vibratory sheepsfoot is insurance against pond leaking. We don't want you coming back and saying your pond is leaking. "You dig a hole but BUILD a pond". Know the rules and guidelines for creating a well compacted thick clay liner.
2. Shallow water is your enemy for growing lots of unwanted pond plants. IMO you are better smaller and deeper rather than larger and shallower unless you want a duck hunting pond. Pond plant and weed problems always occur in the shallow water. Design the pond with how to best aerate it.
