Middle Level Navigations Combined

The Middle Level Navigations is an extensive and unique network of waterways in the Fenlands of eastern England, known for its flat, expansive landscapes and its intricate system of rivers, drains, and canals. Covering parts of Cambridgeshire, Norfolk, and Lincolnshire, the navigations connect the River Nene in the west to the River Great Ouse in the east. Historically, this network played a crucial role in the draining of the Fens and provided vital transport routes for agriculture and trade in the region.

History

The Middle Level Navigations have their roots in the 17th century, when large-scale drainage projects were undertaken to reclaim the Fens from marshland, led by figures like Sir Cornelius Vermuyden, a Dutch engineer. The waterways served as both drainage channels and navigable routes, critical for transporting goods, especially agricultural produce. Over time, these routes became less commercially important with the advent of railways and roads, but today they are popular with leisure boaters and anglers.

Locks and Features

The Middle Level Navigations has six locks in total:

  1. Ashline Lock in Whittlesey
  2. Salter’s Lode Lock, connecting to the tidal River Great Ouse
  3. Stanground Lock, linking to the River Nene
  4. Marmont Priory Lock
  5. Well Creek Sluice
  6. Old Bedford Sluice

These locks vary in size and character, reflecting the unique demands of both navigation and flood management in the Fens. Boaters using this waterway must take care with tidal sections, particularly at Salter’s Lode and Denver Sluice, where they need to time their passage carefully to navigate safely.

Connected Rivers and Canals

The Middle Level Navigations are strategically placed between two major rivers:

  • River Nene: To the west, it connects via Stanground Lock near Peterborough, giving boaters access to the East Midlands and the Grand Union Canal system.
  • River Great Ouse: To the east, it links through Salter’s Lode Lock and Denver Sluice, providing a connection to the waterways of East Anglia, including Cambridge and Bedford.

It is also possible to connect to the Fenland Lodes, a series of smaller, lesser-known drainage channels that also offer navigable routes for small boats.

Interesting Features

  • Whittlesey Mere: Once one of the largest natural lakes in England, it has long since been drained, but the canal passes close to its historical site, reminding travelers of the significant changes the Fens have undergone.
  • Horseway Channel and Welches Dam: Part of the historic Forty Foot Drain, this section of the navigation is notable for its straight, ruler-like precision, a testament to its engineering roots.
  • Denver Sluice Complex: This is a major engineering marvel, regulating water flow between the tidal River Great Ouse and the Middle Levels. It has been crucial to the area’s flood defenses since the 17th century.
  • Wildlife and Fenland Landscapes: The Middle Levels traverse some of the most remote and peaceful areas of the Fens, home to rich wildlife, including herons, otters, and a wide variety of bird species. The landscape is striking in its flatness, with vast, open skies that stretch endlessly across the horizon.

Navigational Challenges

Due to its role in both flood management and navigation, the Middle Levels have a distinctive character. Water levels can vary considerably depending on the time of year and weather conditions, and some sections are tidal. Additionally, the long, straight drainage channels can offer little protection from the wind, which can sometimes make navigation tricky for smaller boats.

Despite these challenges, the Middle Level Navigations offer a fascinating glimpse into the engineering feats that transformed the Fens and provide a tranquil and scenic route through one of England’s most distinctive landscapes. The waterways are less crowded than more popular canals, making them ideal for boaters seeking solitude and a deep connection with the region’s history and environment.
