some thoughts...
First of all, excellent approach digging test holes since soils maps are not always that dead-on accurate...but...as Ewest points out, you also already have a very good test hole to judge by. What is the Plasticity Index for the soil type? (as noted by Bob Lusk in another parallel thread and discussed in an article in Pond Boss...2 issues ago). Who's doin the engineering and gonna push the dirt? Lastly, please indulge me....are they chicken shacks?
Welcome to the show...I'm pretty new here, too...this would be my first exposure to a puppy pond.
