Be aware that many dirt contractors you hire for creating fill dirt will just dig hole. You build a pond and dig a hole. Be sure you read through this very good pond building thread noted in the link. Soil and basin proper compaction is critical for building a minimal leakage pond. There are many many posts here from disappointed owners with improperly build leaky ponds. Do it right the first time because fixing a leaky pond can cost as much as it did to build it.
