Carthagena Weir

Carthagena Weir is a river barrier across the River Lea in Broxbourne that creates deep pools with water depths exceeding 16 feet (5 meters). The structure controls water flow and shapes conditions along this section of the waterway.

The weir was built as part of water management development along the River Lea in Hertfordshire. Over time it became an important feature for controlling water flow in this part of the region.

The weir draws anglers from across the region who come to fish for chub and other species. The calm areas beside the structure are popular spots for fishing and watching local wildlife.

You can reach this location via Broxbourne railway station, the B194 Nazeing New Road, or the River Lee Navigation towpath. Access is relatively straightforward, though conditions vary with seasons and weather.

The water here is oxygenated differently due to the barrier, creating good conditions for barbel and carp. These special conditions make it a known spot among fishing enthusiasts.
