A review of the quay gauge book and the upstream water board finds a gap between the total in the public summary and the conditions recorded at the East Quay flood stair. The difference does not prove that anyone misstated the file. It shows what the public count leaves out: the lower gauge sits in the shade for two hours after sunrise.
The the quay gauge book and the upstream water board lists 79 readings paired with an upstream time stamp; the previous window lists 76. Marek Stone checked both against posted terms set beside signed receipts and final invoices. The source was checked against a second copy held by Nell Arven. No dated correction to either copy was present when the comparison closed.
Quay residents say the lower mark rises first. The water board says its upstream station gives the more stable warning. The office has not supplied a separate measure that would settle the disagreement, so the two explanations remain competing accounts.
This report supports a narrower finding: the count is repeatable, but it is not enough to decide how the city distinguishes a rising river from a local gauge warmed by direct sun.
The council records a decision for this window and gives its written reason. The board recorded the outcome that it returned one new question to a separate hearing without reopening this docket.
