WRAP: Drought-hit Panama Canal causes marine traffic jam

The drought-hit Panama Canal will maintain restrictions on the passage of ships for one year, a measure that has already led to a marine traffic jam as boats line up to enter the waterway linking two oceans. The canal is facing a shortage of rainwater needed to transfer ships through locks that function like water elevators.

Each ship moving through the canal requires 200 million liters of freshwater to move it through the locks, provided by two artificial lakes fed by rainfall in a surrounding watershed. The lakes also supply drinking water to half the country of about 4.2 million people.
