River Nene

Quick Facts

• River Nene (Environment Agency navigation): approximately 91 miles from Cotton End Lock (Northampton) to Wisbech, with 38 locks
• River Great Ouse and tributaries: approximately 156 miles total network including the Cam, Lark, Little Ouse, Wissey and Old West River, with around 22 EA-managed locks
• Middle Level Navigations: approximately 100 miles of Fenland drainage channels including the main shortest route Peterborough to Salters Lode (28.5 miles, 3 locks)
• Connects: Nene — Northampton (Grand Union junction via the Northampton Arm) → Peterborough → Wisbech (and the Wash via the tidal Nene). Middle Level — links the Nene to the Great Ouse via Salters Lode/Denver Sluice. Ouse — Bedford → Ely → Cambridge (via the Cam) → Denver → King's Lynn (and the Wash).
• Build period & engineer: rivers improved progressively from the 17th century (Vermuyden's Fen drainage); modern lock structures Victorian and 20th-century. Middle Level system largely 17th-century drainage works, navigable as a side benefit.
• Boat dimensions: Nene — max length about 78 ft, beam 13 ft, headroom 6 ft 9 in (Lock dimensions about 26 m by 4.6 m). Ouse — max length about 60 ft, beam 11 ft (Hermitage Lock the limit). Middle Level — broadly similar. Many bridges have low air draught.
• Typical cruise time: 2 weeks for the Nene-Middle Levels-Ouse "Fenland Ring" route at a comfortable pace

What's it like to cruise?

A vast, quiet, lock-light, river-and-fenland network that feels a long way from the busy Midlands canals. The Nene runs through the wide pastoral Nene Valley — handsome stone villages, big skies, distinctive guillotine and side-paddle EA locks. The Middle Level is the engineering oddity — straight-cut drainage channels through the Fens, often below the level of the surrounding farmland. The Ouse and its tributaries are gentle, pastoral and culturally rich, with Ely Cathedral, Cambridge city and the Bedford river meadows all reachable by boat. Tidal sections require careful planning at Salters Lode/Denver and on the lower Nene and Ouse.

Highlights along the route

• Nene: Oundle — handsome stone market town.
• Nene: Wansford and the Nene Valley Railway — preserved steam line crosses the river.
• Middle Level: Salters Lode and Denver Sluice — the dramatic tidal junction between Middle Level and Ouse.
• Ouse: Ely — the cathedral on the hill, central moorings on the Great Ouse.
• Cam: central Cambridge, with Jesus Lock and the Backs.
• Ouse: St Ives and St Neots — pretty river towns.
• Ouse: Bedford — the upper terminus and the river through the town.

Connections & cruising rings

Nene connects to the Grand Union via the Northampton Arm (17 narrow locks). Middle Level links Nene to Ouse. Ouse links to the Cam and the other tributaries. Forms the "Fenland Ring" (Grand Union → Nene → Middle Level → Ouse → return by road or via tidal Wash). Long-term Fens Waterway Link aims to reconnect Boston/Lincoln to the Nene/Ouse via the South Forty Foot Drain.

Suitable for

Confident boaters who enjoy quiet, lightly-cruised waters. The tidal Salters Lode/Denver passage is the technical highlight and requires booking and slack-water timing. Many EA locks on the Nene are operated by hand with substantial guillotine gates — different from CRT canal locks, and worth practising.

Practicalities

• Licences: separate Environment Agency licence for Nene and Ouse; separate Middle Level Commissioners registration. Long-term cruisers buy a "Gold" licence for combined coverage.
• Tidal bookings: Salters Lode and Denver Sluice work to tide; book with the lock-keepers in advance.
• Water and elsan: well-distributed but more spaced than on canals — plan tank levels.
• Mobile signal: patchy across the Fens.
• Pump-out: limited — at major marinas only.
• Air draught: Nene has some low fixed bridges; check before booking.

Best time to cruise

May to September. Summer storms and floods can shut sections at short notice. The Ouse and Cam are at their best in early summer.
