Lake Mead can still hold water when Hoover Dam can no longer perform some of its most important jobs. The concrete does not have to break for the system to reach a limit. This Failure Chain documentary follows the links between hydraulic head, Lake Powell, downstream delivery and Southern Nevada’s deep intake. Lower pumps protect access.

Future limits and forecasts are distinguished from observed conditions. The film includes earlier site visits; footage is not a live water-level measurement.
