I want to build a one acre pond. I had the site inspected and that part looks good. I had two soil samples sent off to the extension office.

Sample_____1 foot_______4 foot
Sand (%)___52.0_________68.0
Silt (%)____22.0_________14.0
Clay (%)___26.0_________18.0
Soil Type___Sandy Clay___Sandy Loam
___________Loam

What do you think?
Is there enough clay or will it leak?
How do ponds in Florida work if they are all sand?

TIA
