About the only way I can think would be pumping it out continuously or running pipe from the lowest spots out into a drain field. Too much work for me! I love the look of it as a pond but if you don't want it then it would make a nice gathering spot for family and friends to sit. If you have a hill on your property nearby the pond, lower than the pond you could run a pipe underground that comes out to the hill and then water comes out and runs down. It better not effect anyone else's property tho or they will complain big time.
