Pond Boss Forums POND CONSTRUCTION Soil questions Another Soil Question

Im totally new to the pond thing , just starting to investigate if its possible to have a small pond on our family farm.
But I do have this soil stuff, and from what Ive read it doesn't seem promising...

Personal Notes : The site im looking at is the low point between several unused fields, there's a lot of tress and vegetation in that area that stays greener , also stories from my dad said that there was a small pond there in the spring time when he was a kid...

I guess I would be looking at an excavated pond and the well fill option.

Welcome to the forum MaxExp82... You've found the right place to get your questions answered!

Hang tight, someone who knows dirt and pond building will be along to help you out... But if it is only 32" to bedrock, it don't sound good to me but I know beans when it comes to soils and pond building.

Welcome abord you are going to love this place.

Are there any other ponds near you?
That will tell you just as much as the soil tests.

What size do you want to build.

There is 2 Man Made ponds and 1 Natural Pond within a mile.

The area im looking at making it probably has a bedrock depth of 10-12 feet.

My plan is for a 1/2 acre pond..

Sounds a lot more plausible... Otto knows his dirt, so take his advice.
