Pond Boss Forums POND CONSTRUCTION Selecting a site Contructing a pond over a spring or beside a spring?

This might be a longshot but I've seen drawings where an underground funnel was installed to funnel the spring water into a central location (kind of an underground diversion on the spring. At the center was a plastic culvert, buried vertical, with the top sticking out of the ground and a bunch of holes in the "upstream" side of the vertical culvert. The culvert would fill with spring water up to some equilibrium level. If you've got a spring that truly flows 20GPM minimum, then it might have enough pressure to fill the culvert completely. If the new surface of the water in the culvert is above the water level of the pond, bingo, gravity feed. If not, you have quite a storage tank with the full culvert that you can pump into the pond. You could automate the pump with a float switch.
