Jim, yes i agree, lots of good stuff on this site. I noticed on your profile that you are a home inspector. then you might have good knowledge of...at what depth can you get a good watersource if you were to drill a well? i had looked into drilling a well after i first started my pond. the thing that got me here was the depth i'd have to dig to get a good well supply. my house well is i think 300 feet. my neighbor had well drilled for his farm animals and it was i think around 500 feet deep. his ran around 5-8 grand. i can't remember exactly what the charge per foot was, and also depended on how much...i can't remember what it is but has to do with a "sleeve" like mechanism thru the first certain layers they have to drill thru/ the "unsteady soil" mark
