Hertford Castle Weir - Weir Setup

Weir Setup

Castle Weir has 3 sections:

  • A vertical 70 cm drop onto a second 30 cm concrete block, situated in a stilling pool. The stilling pool overflows into a tunnel which leads under the road. The 70 cm drop has two electric gates which move vertically in high flows.
  • 5 padlocked sluice gates. Rarely used, as these are manually controlled by British Waterways.
  • Stepped drop for high flows.
