Scenario outcomes

Where each path ends and how low it dips — the trough matters most for restriction risk.

Reference thresholds

Restriction watch line
~50%
When storage heads toward 50%, tighter water restrictions usually enter the conversation.
Critical pressure zone
~30%
Below this range, severe restrictions become much more likely.
