At the upper reservoir cut into the west face, Pera Durn keeps the opening docket file beside a narrow spillway whose lip sits one thumb above the older survey mark. The two details are easy to miss in a summary: one is a line in a ledger, the other is the condition that decides whether the line is useful.
Pera Durn is the water surveyor for the west face. On this thaw season visit, the work begins with the reservoir depth marks and the household release schedule; only after the entry is checked can the crew say what the rule asks of the people below.
36 depth marks checked at dawn were entered this cycle, compared with 34 in the prior file. The figure is one part of a longer handoff. Tavi Orr checked the reservoir depth marks and the household release schedule against the field notes. The method is to trace a system from its control gate to the last household it is meant to serve; it confirms the entries, but not every interpretation attached to them.
The reserve proposal uses a recent high-water mark; older surveyors say the mark was taken before the spillway was cleared. The current record does not settle that disagreement. Residents closest to the work describe the difference as a route, a wait or a shift that cannot be moved on a slate. Their accounts have been attached to the docket rather than folded into the total.
The clerk has matched the claim to its source register and named the missing record. The entry belongs to the opening docket file at the upper reservoir cut into the west face. The survey office will publish both measurements and their dates side by side. The next visit will show whether the revision travels beyond the office that wrote it.
