Denver Sluice, Great River Ouse walk FRW

The Fen Rivers Way, a long distance path running for nearly 80km between the historic settlements of Cambridge and King's Lynn, traces the course of rivers that drain slowly across the Fens into the Wash. The walk along the river here at Denver takes in part of the Fen River's Way.

Denver Sluice is the focal point of the flood defence system that protects the low lying Fens. The sluice was first built by Cornelius Vermuyden in the 1650s, but the present structure was built in 1834 by Sir John Rennie, before being enlarged in the 1920s. Running parallel to the River Great Ouse is the Relief Channel, the final link in the drainage system, completed in 1964. The two waterways meet at King’s Lynn, the historic port on the edge of the Wash.
