You have to be really careful with bamboo, it can REALLY take over and run off. We were visiting in Virginia, saw where the bamboo had gone wild on the sides of the railroad tracks. VERY strange feeling walking under that stuff, which contained many sizes of bamboo. It was between a historic site and parking area. It literally towered over everything around. Did not allow any other undergrowth or trees in the growing area. Weird look to it as well, when the stuff is over 40ft tall. Sure made me RECONSIDER AGAINST using ANY bamboo at my place.

Most bamboos are not bothered by cold or freezing, happens in their native settings. So that natural control won't work with this plant.

Bamboo is considered extremely invasive, really hard to regain control once it starts spreading. Not sure if your limestone basin would prevent spreading, plants can be very determined.

I would look at some other options for a damp site, using native plants. Willows might like the location, use the extra water. Or go for cattails, for a bog type area. Local native plants provide food for the local birds and animals. Not sure any native wildlife will use bamboo for food, help you control it.

You might get more detailed information on some of the garden sites, like Perennials, Shrubs, Landscaping, about bamboo problems.

I think you should try the Bamboo forum Some bamboo is very suceptible to freezing, some is not, some types are big and aggressive, some grow to 12" tall and some stay in small clumps and do not spread over an area more than 8'X8' .

The biggest problem I can see is that the pond might refill and your bamboo is unlikely to do well under 4' of water for an extended period of time.
