Opps, I didn't give much detail. No stream, land is all flat with all spoil bermed on site. How about using core drilled rocks for a 'bubbling' spring into an upper pond that would have two waterfalls into the big pond instead of the biofalls? I kind of would like to get away from the regular or typical looking pond and make it look more natural, although the client does want a fountain.
Do or do not. There is no try. yoda
