dam up

To save more water in rainy months and increase supply in drier times, it wants to dam up the nearby Indio River, and pipe the fresh water into Lake Gatún, the canal's main reservoir.

Stewart ended his third Monday night broadcast since returning to “The Daily Show” by eulogizing his beloved three-legged pittie mix — tearfully, despite his strongest efforts to dam up that river.

The process dirtied lakes, cut down forests and dammed up rivers.

He says it will take at least six years to dam up and fill the site.

In 1992, five villages in Galicia, Spain were flooded on purpose when a river was dammed up to create a large reservoir.
