I am driving a shallow well about 15 ft. deep and hope to hit water at lake level at 10 ft. This is 20 feet inland from the high water mark of a clear water lake. I have a 40 ft. vertical climb to lift the water to the cabin, It is 400 ft. from the well and never more than a 25 degree slope at any one point with the average slope about 8 degrees. The elevation of the area is about 1200 ft above sea level. What kind of pump will do this? What size pump? Should I use 3/4 in. pipe out of the ground or something larger in diameter?
 
You would need to set the pump at the well. A shallow well pump can suck from 10' down and push up the 40' and 400' away but, I would use 1" or 1.25" pipe. A shallow well pump cannot suck from 40' up and 400' away, so you can’t put the pump at the house.

the pipe friction at 10 GPM =~ 72' head, and if you want 30 PSI that's another 70', plus 10' plus 40' = ~200'. Assuming a pump efficiency of 60%,
HP = GPMxHD/(40xEFF)
= 10(200)/(40)(60) = 0.8 hp. Call it 1 hp.

96% of well depths listed on this forum are deeper than 15', with the avg. being 240'. Your odds may not be good.
