A rain-swollen lake. A small town dependent on fishing revenues. A rivulet of water seeping through the rocks beneath an earthen dam. These are the suspense-generating ingredients of this onrushing, all-star Irwin Allen production. A helicopter pilot (Robert Culp) and a youngster (Eric Olson) first discover the dam's leaky secret. But local leaders refuse to face the drain on the town's troubled economy that draining the lake would cause. A high-and-dry solution is not in the cards. Martin Milner, Barbara Hershey, Richard Basehart, Cameron Mitchell, Teresa Wright and two stars of Allen's smash The Poseidon Adventure, Carol Lynley and Roddy McDowall, all try to keep afloat when the wall of water hits and the special effects kick into high gear. Take a dive into the raging currents of this topflight adventure.
