Lake St. John — Lake St. John Water Works issued a boil-water notice Saturday for all of its customers.

Water Works office manager Ruby Andrus said a break in water main occurred. The system was shut down, Andrus said, and repairs made to fix the break.

The state health department, however, requires that a boil-water notice be issued anytime the system has to be shut down, Andrus said.

All customers are asked to boil any water before drinking or using in cooking.

Samples are being sent of the health department and must be approved before the advisory can be lifted.

Lake St. John Water Works serves 642 customers.
