I would pay the SWCD a visit - face to face talk with the district supervisor - professional may get you more results than general office staff. This type of service is what the SWCD was founded on.

Also try contacting these Dayton local fish farms who should know of some decent pond builders in your area - region. Their helpfulness probably will indicate how well they will serve you when you need fish or management products.

Further away but still in the region and should be knowledgeable. I know the Jones brothers from way back in the 1980's.

Further away in Urbana is Freshwater Farms but may know of a builder in your area. I know Dr. Dave Smith via Ohio Aquaculture Assoc

We have a PB member (school teacher) here from your area who has a fairly new pond. He might be in My Private Messages list and able to give some help. I will look for his name.
