PL, IIRC bald cypress are deciduous and will contribute alot of spent vegetation to pond as they get older. if yer aerating that might not be a problem. as for water consumption, i dont know for sure, but would guess they use less than willows but would still use increasing amounts as they mature and grow their "knees". being back in indiana (you get summer rain.....i dont) you might be ok....it would be the kiss of death for me. in any case, if you have enough summer water to keep yer pond reasonably full, they will be beautiful.

i tried planting some below my dam in creekbed, but the deer got them before they could get established.

GSF are people too!
