15 gauges report along the Shannon. 1 of them reads below normal for the date, and none is running high.
On this page the river runs through Roscommon, Westmeath, Galway, Offaly and Limerick. Reading the gauges in order shows how a rise or a dry spell travels downstream, usually over a day or more on a big river. Autumn is often a low point for rivers after the summer, until steady rain returns.
