Question: What natural body of water does Turnford Brook and Borough of Broxbourne have in common?
Context: Hachiji dachi (八字立:はちじだち ) is a stance used in karate.  In English, "hachiji" roughly translates to "the character for eight," but in context means something more like "shaped like number eight."  Note that this refers to the shape of the "kanji" for the number eight: 八, not the arabic numeral "8".  "Dachi" (立:だち ) , the pronunciation of "tachi" (立:たち ) when the word is second in a compound, translates to "stance," referring specifically to the body's position from the waist down.  The term "hachiji dachi" is frequently used interchangeably with ""shizentai"" (自然体：しぜんたい ) , or ""shizentai dachi"", which translates to "natural stance" (literally, 'natural body,' or 'natural body stance').  In most styles, "shizentai" is identical to hachiji dachi. Wormley is a village in Hertfordshire, England.  It is within the Borough of Broxbourne.  The village is part of the census ward of Wormley and Turnford, which had a population of 8,146 at the 2001 census.  It is in the civil parish of Bayford, Hertfordshire. Virginia Water Lake lies on the southern edge of Windsor Great Park, in the borough of Runnymede in Surrey and the civil parishes of Old Windsor and Sunningdale and Ascot in Berkshire, in England.  It is a man-made lake taking its name from a natural body of water of the same name.  There is a village of Virginia Water which stretches out to the east of the lake.  The grounds of the lake, nearby Fort Belvedere, and the Clockcase are all Grade I listed on the Register of Historic Parks and Gardens. A swimming hole is a place in a river, stream, creek, spring, or similar natural body of water, which is large enough and deep enough for a person to swim in.  Common usage usually refers to fresh, moving water and thus not to oceans or lakes. The Borough of Broxbourne is a local government district and borough in Hertfordshire, England.  Its council is based in Cheshunt, other towns include Broxbourne, Hoddesdon and Waltham Cross.  The eastern boundary of the district is the River Lea.  The borough covers 20 sqmi in south east Hertfordshire having a population of about 96,000. Turnford Brook is a minor tributary of the River Lea.  The brook flows through the Borough of Broxbourne for approximately 3 mi . A great pond in the United States is a pond or lake that is held in trust by the state for public use.  Generally, any natural body of water that is larger than 10 acre in size is public water.  In certain New England states, this legal definition exists at both common law and statutory law. 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. Turnford is a village in the Borough of Broxbourne, in Hertfordshire, England, in an area generally known as the Lee Valley.  It is bounded by Wormley to the north, Cheshunt to the south and west, and its eastern boundary is formed largely by the Lee Navigation.  Central London at Charing Cross is approximately 18 miles south.  At the 2001 census, together with Wormley, the village had a population of 8,146 in 3,399 households. 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.
