Raising the dam raises several issues. They include (but are not limited to):

* state and local regs on capturing surface water. Here in Texas, generally (big word) landowners may capture up to 200 acre feet without a permit. It's more restrictive in other states.

* dam construction. As pointed out by the previous post, water weighs 8 pounds a gallon. Make sure the structure can handle the extra load.

* spillway. A pond is designed to trap water, yes, but you must be able to release it, too. Is you spillway adequate to move more water?

* leaks. Raising the dam could send the water level into cracks and fissures that previously did not come into play.

* trees. Many species of trees suffer when their roots are inundated. As a West Texan, I view trees as a precious commodity. Consider.
