Witham Navigable Drains

The Witham Navigable Drains are a complex system of drains that connect to the river Witham at Anton's Gowt Lock.  The Drains are primarily for drainage purposes and are drained down in winter, when navigation is not possible.  See navigation notes for Witham Navigable Drains by IWA's Lincolnshire Branch, which describes the various navigable drains, how they are connected and limiting dimensions.

The Drainage Board responsible for the area covers just under 400 miles (702 km) in a catchment area of about 101,000 acres (40,928 hectares), of which just 60 miles (96.5 km) are navigable.
