If trees are exposed to constant flooding of the roots they can be deprived of needed air that is necessary to carry out normal root functions. With this in mind, if normal root function is curtailed it can cause the tree to become stressed. In addition the tree may attempt to expell excess water through the leaves which in turn, if prolonged, can cause leaves to drop. The presence of Carpenter Ants also are a sign of additional stress which might be diseased or decaying wood. It would be wise to have the tree inspected by a licensed ISA Certified arborist. You can find these folks at ISA-arbor.com and put in your zip code to give you a listing of local certified arborists.
