Hertford Castle Weir


Hertford Castle Weir is a weir located in Hertford near to Hertford Castle and next to Hertford Theatre.
Its function is to connect the upper River Lea to the canalised section that runs through Hertfordshire, North London into the River Thames. The section of the river above Castle Weir is not deep enough to support barges or narrow boats, but is navigable by row boats, canoes and kayaks.
The weir marks the start of the River Lee Navigation. It is overlooked by a function room at the Hertford Theater.

Access

Just off Mill Bridge in the centre of Hertford town, beside the Castle Hall.
A small bridge runs from Mill Bridge over the secondary drop to a car park. A step upstream from this bridge allows access to the top of the weir.

Angling

in the weir pool is possible, but tricky due to pontoon access at the weir pool. Anglers often stand on the stepped weir drops, but this is discouraged due to the damage that is sustained to the weir itself.

Weir setup

Kayakers and canoeists regularly use the weir for practicing whitewater skills and playboating.
