Solution
The term for the opening used to drain out excess water in lakes and ponds after they are full is a) Weir. A weir is a barrier across a river designed to alter its flow characteristics. In most cases, weirs take the form of a barrier, smaller than most conventional dams, which causes water to pool behind the structure (not unlike a dam) and allows the water to flow over the top.
