We have 4 gauges on the Le Coulon. 2 of them read above normal for the date, and none is low.
On this page the river runs through Alpes-De-Haute-Provence and Vaucluse. 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.
