Hi Geoff! Welcome to the forum! Is your pond a groundwater, spring, or earthen dam and run-off source? Each pond water source poses it's own unique needs to drain, sterilize and renovate.

Crappie in a one acre pond are a LOT of work to manage, so you will want to read some old archive posts that catch your eye and get some ideas on what you'll want and get an idea of management time you'll need to invest.

A couple great books as resources to help you learn a lot of terminology and about the aquatic ecosystem would be Bob Lusk's, Perfect Pond, Want One...and Mike Otto's, Just Add Water.
