EA forecast (official)
Flood predictions aren't generated for
lock / structure gauges —
their levels are driven by gate operation,
not by catchment rainfall, so the forecast models would have no skill here.
Downstream level
7 days
The level on the DOWNSTREAM side of this lock/weir structure — a separate EA
measure from the main (upstream) reading shown on the Current tab. Threshold bands
are computed from this gauge's own downstream history.
Geographic coordinates may reflect the access point for the gauge, and not the precise location in the watercourse that it is taking readings from.
