I have a spring fed creek at the back of my property and I am considering installing a pump to provide irrigation to my backyard initially and later down the road, I would like to pump water up to a pond/waterfall (yet to be built). The maximum elevation of the lawn to be irrigated is 12 ft above the water level in the creek. The water in the creek is about 8-10 inches deep, although I could make it a little deeper by removing some rock. Unless disturbed by rainfall the water is crystal clear. The creek is about 125 ft from the main panel. I intend to install a 40 Amp subpanel about 20 ft from the creek in a patio area.

Any advice/reccomendations for this project would be most appreciated. For example, what size and type of pump...as well as any advice on piping.
