Hadleigh is an ancient market town and civil parish in the Babergh district of Suffolk, England. The town is situated next to the River Brett, between the larger towns of Sudbury and Ipswich. It had a population of 8,253 at the 2011 census. The headquarters of Babergh District Council were located in the town until 2017.
The nearest watercourse on the river map is the River Brett, about 10 m from the middle of Hadleigh's gauges. It flows into the River Stour about 12 km downstream.
A gauge downstream shows water that has already passed this point; one upstream sees it first. Distances along the river are from the point on the River Brett nearest the middle of Hadleigh's gauges. From Ordnance Survey’s river map (OS Open Rivers), which leaves out small streams, ditches and culverts, so a nearer one may exist. This describes where water goes on the map; it says nothing about flooding at any address. Contains OS data © Crown copyright and database rights 2026.
