Tykes Water

Tykes Water is a minor tributary of the River Colne in the south of Hertfordshire.
The river rises in a network of drainage ditches west of the A41 near Bushey which feed into the Aldenham Reservoir to the north. The outlet of the reservoir then flows north into the lake in Haberdashers' Aske's School grounds known as Tykes Water Lake. The waters issuing from the lake then flow north to meet a secondary stream, also called Tykes Water, near Kendal Hall Farm.
The combined Tykes Water flows through the centre of Radlett parallel to the railway and then north to join the River Colne near Colney Street. The lower part is also called The Brook.[1][2]
The secondary Tykes Water, also known as Borehamwood Brook on some maps, rises to the south of Borehamwood near Yavneh College and runs north through the town, where it has been dammed to produce ornamental lakes in Aberford Park. It then runs north through open country.
A minor tributary collects water from farmland north of Borehamwood and also joins near Kendal Hall Farm.
Kitwells Brook joins the main stream just north of Radlett and drains land to the east in the direction of Shenley.
In popular culture

Tykes Water Bridge in Aldenham Country Park features in the opening credits of the Peter Cushing and Christopher Lee film, Dracula A.D. 1972, and is used in several episodes of the Diana Rigg and Linda Thorson series of The Avengers . Earlier, in 1966, it was used as the setting for the opening sequence of "The Saint" episode "Little Girl Lost" featuring Roger Moore.
