Carthagena Fishery — River Lee section and weirpool

Carthagena Fishery gives you roughly three-quarters of a mile of coarse river fishing on the River Lee, plus a proper deep weirpool and mill stream at Carthagena Lock. It’s a cracking Hertfordshire venue, particularly noted for specimen barbel, chub and bream.

The lowdown

  • This is a long, varied bit of river, with the Lee section running for approximately three-quarters of a mile. Plenty of water to explore rather than just sitting on one peg all day.
  • The weirpool is the headline feature. It drops to more than 16 feet, so there’s serious depth to work with and plenty of water column to search.
  • The river and weirpool are coarse-fishing waters, with barbel, chub, bream, dace, roach, pike, eel and gudgeon in the fish community. Barbel, chub and bream are the venue’s big draw.
  • Flow and depth will vary around the river section, while the weirpool gives you a deeper, steadier-looking option. Have a good look before setting up.
  • Trotting and feeder fishing are the obvious river approaches, especially when there’s a bit of colour or the flow is pushing. Pick the crease and fish tight to features.
  • For the deeper weirpool, a patient feeder approach can make sense. Keep things tidy and work different depths rather than automatically fishing hard on the bottom.
  • Day tickets for the River Lee are available from the riverbank or the on-site shop. The weirpool is available on a season ticket, so it’s a different ticket setup.
  • The fishery is not open for night fishing, and you can only fish during the stated permitted fishing times. No sneaking in for a cheeky dusk session outside the rules.
  • Parking is beside the river after following the access track from Nazeing New Road. You reach the fishing area via the footbridge over Carthagena Lock, and Broxbourne station is close by.

Methods: Trotting and feeder fishing suit the river section, while the deep weirpool rewards a careful, patient approach. Read the flow, find the crease and keep moving if a swim isn’t producing.
