Hoping to build a 3/4 acre pond in the bottom below our house in lovely Oklahoma red dirt. Used a jar test to get an idea of soil composition to see if it's even an option (I know a jar test is not a thorough soil analysis). You can clearly see the sand layer in the bottom half of the dirt sample, but the top half of the jar looks like all silt to me? Can someone with more experience tell me what they see? The sample is from about 4 foot deep. Am I wasting my time?
