Carshalton Springs and Watercourses

February 2014

John Phillips writes: "Carshalton was a village of springs and watercourses. The al bit of its name is derived from spring or well. The springs and water courses – which now flow only after an exceptionally wet winter – used to flow all the time.

The current flow is the highest I have ever seen although I have only been interested in the water courses since the late 1980s.

The last really big flow was in 2000-1 following a very wet autumn. There was then somewhat under a metric ton of water per second flowing over the gauging weir in The Grove just downstream of Carshalton Ponds. A few days ago the measuring part of the weir was full and water was flowing over the surrounding brickwork. I have not seen this before. The highest recorded level at the weir was on 20 July 2007 but this was caused by a massive thunderstorm not ground water. The river level at the weir may be found on the Environment Agency’s web site HERE."

1

The Carshalton House Lake now in the grounds of St Philomena’s School. This is fed from the spring head at the southeast end of the lake. The lake has been altered several times. It was given its present form in the mid-18th century

2

The Water Tower. Built about 1718 as part of the gardens of Carshalton House. It contained a cold bath, water driven pump and orangery. Find out more about the Water Tower HERE

3

Margaret’s Pool. Originally the Water House Pond through which West Street Passed in a ford. It was cleaned and improved by John Ruskin in the 1870s. The dedication stone and some of the ornamental stone remains. The pool was renamed in honour of Ruskin’s mother

12

Spill way at the end of the Westcroft Canal. The can once extended further north to a snuff mill on the site of the present paper mill close

13

The Grotto Canal. The straight southern end was created in the early 18th century as a water feature in the grounds of a large house which was never completed. The northern section, between Ruskin Road and the High Street, appears to be an alteration of later 18th century date

14

The Hog Pit probably originated as a chalk pit. It existed in the late Middle Ages. It was reshaped as a garden feature in the eighteenth century and supplied water to a mill by Lower Pond

15

The grotto. Built about 1724 as a garden ornament it was once decorated with sparkling slag and glass waste, sea shells red ‘coral’ made of lead. Some of the decoration can be seen in the Water Room in Honeywood
