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.
