Ely water levels

Monitoring stations, source to mouth

No gauged tributary joins the Ely above Ely Bridge River Station on the river map. Streams without a gauge are not counted here.

Each overflow is listed in the stretch above the first gauge its water reaches, from the source down, as on the Gauges tab. A stretch of the Ely includes the smaller streams that join it there.
