Dams don't last forever. Hot and cold weather makes them crack. Water erodes their foundations. They create environmental problems. Eventually, every dam must be repaired, removed, or replaced.

You are a consulting dam engineer, and today, four dams need your attention. It is your job to advise the dam owners whether their dams must be repaired, taken down, or simply left alone. Listen to what the supporters and opponents of each dam have to say.

Like all dam engineers, you must weigh the pros and cons before you make your final decisions. Good luck!

The Problem Dams:

Gravity dam holding back a reservoir		Buttress dam on a scenic river
