Welcome to the forum Guy. Sounds like an interesting start to a thread. If you can get some picture it would sure help. Maybe a damn can be built. Is there any water shed that could help along with the spring? My dad pond is built over a spring on a hill so it has water shed also. It has never went dry maybe down a few feet but don't they all vary somewhat?

The people who say I can't do it can just sit the @^#% down and watch me. Friends call me Rusto I also subscribe to pond boss mag. http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Number=504716#Post504716
