One of the more important jobs that Tom and the staff have (at all hours of the day) is ensuring that the cabins don't get hung up and go aground. Since the resort is on a reservoir that fluctuates up and down as Seattle City Light produces power, the staff monitors the lake level and sometimes employs brute force to move the cabins into deeper water.
Keena, one of the resort supervisors, observes Tom, before providing feedback.
