Hertford Castle Weir

Hertford Castle Weir is a structure built across the River Lea with a stepped design that controls water flow through the area. The installation comprises several sections including a stilling pool that manages drainage beneath Mill Bridge.

The weir marks the starting point of the River Lee Navigation, linking the upper river to waterways flowing through Hertfordshire and London. This connection historically enabled movement of goods and people through the region.

The structure stands near Hertford Theatre and draws locals throughout the year for fishing, kayaking, and whitewater pursuits. The site serves as a gathering place where people practice water sports and spend leisure time.

The weir is easily accessible from Mill Bridge in central Hertford with multiple entry points along the riverbank. Water conditions vary by season and rainfall, so checking current circumstances before visiting is wise.

The pool behind the weir provides specific conditions for experienced kayakers to practice advanced moves, with water levels changing based on weather patterns. These shifting circumstances make it a valuable training location for water sports enthusiasts.
