Gravity dam

Gravity dam holding back a reservoir

Type: Gravity dam
Material: Reinforced concrete
Age: 150 years
Purpose: To create a recreational area and promote tourism
Problem: Spillway is damaged
Budget: $1 million

The Opinions:
"This dam is a danger to society! One of the spillways is clogged with trees and other floating debris, so the dam isn't releasing as much water as it should. The reservoir is becoming dangerously high. It's only a matter of time before the reservoir spills over the dam and the whole thing collapses!"
-- Dam safety official

"Excuse me, but you cannot possibly take this dam down. Don't you see that we have a resort to run here? Dozens of families vacation at our resorts and use the reservoir for boating and fishing. Without the dam, there is no reservoir. Without the reservoir, the local tourist industry will be ruined!"
-- Resort owners

The Options:
Repair the Dam Remove the Dam Do nothing
Repair it! Remove it! Leave it alone!
