Wadesmill is a hamlet in Hertfordshire, England, located on the north side of the River Rib, with an estimated population of 264. At the 2011 Census the population of the hamlet was included in the civil parish of Thundridge. Running through the centre of Wadesmill is the road formerly known as the A10 but now that the A10 by-pass has been built, Wadesmill and surrounding villages have returned to the quiet of former times. The route that was formerly the A10 is an ancient one, with portions of it following the line of the Roman road, Ermine Street. Ermine Street also figures as the former main street in Wadesmill's adjacent village Thundridge.

The nearest watercourse on the river map is the River Rib, about 10 m from the middle of Wadesmill's gauges. It flows into the River Lea (River Lee) about 6.9 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 Rib nearest the middle of Wadesmill's gauges.
