The New River is an artificial waterway in England, opened in 1613 to supply London with fresh drinking water taken from Chadwell and Amwell Springs near Ware in Hertfordshire, and later the River Lea and other sources. Originally conceived by Edmund Colthurst and completed by Hugh Myddelton, it was operated by the New River Company for nearly 300 years until London's water supply was taken over by the Metropolitan Water Board in 1904. Although it was once threatened with closure, a large section of the New River remains part of London's water supply infrastructure, today operated by Thames Water, more than 400 years after it was first constructed. The New River originally followed the land contours but certain parts have been straightened over the centuries. There is a designated walking route along the canal called the New River Path. It is a 28-mile (45 km) long-distance footpath which follows the course of the New River as closely as possible from its source in Hertfordshire to its original end in Islington, London.

The Broxbourne Mill Stream which diverges from the River Lee Navigation just south of Dobbs Weir, is one of the few remaining 'old river' loops of the River Lea, with a relatively natural channel form and a diverse range of habitats. Broxbourne developed as a small settlement for milling at a river crossing point at Broxbourne Mill. Spital Brook empties into the Mill Stream by Nazeing New Road.

Broxbourne Mill is located at the Old Mill and Meadows Site Lee Valley Park, Broxbourne, Hertfordshire.

Spital Brook is a minor tributary of the River Lea which rises in Hoddesdonpark Wood in the county of Hertfordshire, England. Spital Brook flows eastwards from Hoddesdonpark Wood, passing through Barclay Park, the former Hoddesdon Common, on its journey to the Lea, while an unnamed parallel stream to the south has been diverted to form ornamental waterbodies located within the former parkland of Broxbournebury. The stream crosses the Roman road, Ermine Street, before going under the A10 and Cock Lane. The original crossing place or ford of Spital Brook in Cock Lane remains and the original route it took ran parallel to the brook in a north–south direction. The brook passes through its namesake area, Spital Brook and marks the traditional boundary between the two parishes of Hoddesdon and Broxbourne. The stream runs parallel to the Lea Valley Lines by Broxbourne Station until it meets the River Lea close to Broxbourne Riverside, the former Broxbourne Lido. Spital Brook's profile is relatively steep for a Hertfordshire water course, and loses approximately 50 metres of height over the 1 kilometre upper section. Due to the brook's small catchment area, unless it is raining heavily, only the lower reach is likely to have water in it.
