Thanks Steve, sounds like sound advice, one thing i neglected to say in my post is the upland area is aprox 500 ft higher then the location of the springs. with that said , the head pressure would be more then sufficiant. 500ft is a minimum the slope continues up after that. id have to get a detailed elevation map to get the exact point of highest elevation. I do know that aprox 500 feet up, there are rather large areas of undeveloped level ground (100 or so acres maybe more).
An interesting dilema, if and when i drill, do i go straight down, angle in, or sideways into the slope? The slope is probably around a 7/12 pitch.
