Start with the quay gauge book and the upstream water board. It is the source used to decide how the city distinguishes a rising river from a local gauge warmed by direct sun; it is not the decision itself. The rule only works if the source describes conditions at the East Quay flood stair.

Known: the current file counts 27 readings paired with an upstream time stamp, compared with 21 in the prior window. Anew review window opens with a dated question and a named clerk. The entries have dates and a named clerk.

Disputed: Quay residents say the lower mark rises first. The water board says its upstream station gives the more stable warning. One side emphasizes the posted total; the other points to the lower gauge sits in the shade for two hours after sunrise.

Why it matters: the decision determines which residents can rely on the service and which staff must carry out the change. The file does not settle that by itself.

Next: The Year first, market fall window 2 file remains open for its scheduled decision. Asecond gauge will be read at the same hour on both sides of the quay.
