Pond Boss Forums POND CONSTRUCTION Selecting a site Found clay - but at 25'

Friends,

At our planned pond site, we found clay at 25' but were expecting it at 12' (based on the soil study / county engineer). As such, we'll have to get clay from somewhere else on the property if we're going to have a depth of 12-15 feet and a clay liner.

Of note, there is some water seeping into the pond site (currently a 20' x 60' large trench) indicating surface water at 11-14 feet. The adjacent property is in a FEMA flood zone and is low ground. The pond site is on relatively flat ground and is the lowest point (elevation) on the property.

Is there an option to not have a clay liner and still have the pond hold water?

Thanks,

Joe
