Niri Flint opens reservoir marks, pump log copies and the public archive index at the archive niche at Moss Reservoir. Before anyone changes a mark, the crew checks the earliest level marks use a handspan scale that changed between crews. The first seep period sets the pace of the work.
The page holds 91 historic marks with a date and reading location. Niri Flint reads the preceding count, 88, before the next line is entered. A number without a date would not tell the next crew what changed.
The archive wants one present-day scale. Pump crews ask that old marks keep their original unit alongside a conversion. Here the difference is visible between the posted rule and the route, service or shift just beyond the door.
The clerk closes this route file and gives the next window a fresh walk. The board closed this docket after it added a second branch mark for the next passage window. The next window starts with a fresh record.
The shift closes with the source page attached to the board. The next file uses a new date and scope.
