Nell Arven opens the quay gauge book and the upstream water board at the East Quay flood stair. Before anyone changes a mark, the crew checks the lower gauge sits in the shade for two hours after sunrise. The cold harbor period sets the pace of the work.

The page holds 66 readings paired with an upstream time stamp. Nell Arven reads the preceding count, 63, before the next line is entered. A number without a date would not tell the next crew what changed.

Quay residents say the lower mark rises first. The water board says its upstream station gives the more stable warning. Here the difference is visible between the posted rule and the route, service or shift just beyond the door.

Workers and residents submit accounts before the public hearing closes. The Year first, cold harbor window 2 file remains open for its scheduled decision. Asecond gauge will be read at the same hour on both sides of the quay.

The shift closes with the source page attached to the board. The next file uses a new date and scope.
