Three Rivers District

Three Rivers is a local government district in south-west Hertfordshire, England. Its council is based in Rickmansworth. The district borders Hertsmere, Watford, St Albans, Dacorum, Buckinghamshire, and the London boroughs of Hillingdon and Harrow.

History
Three Rivers District was created on 1 April 1974 under the Local Government Act 1972, covering the whole area of two former districts and most of a third, which were all abolished at the same time:
 * Chorleywood Urban District
 * Rickmansworth Urban District
 * Watford Rural District, except the parish of Aldenham, which went to Hertsmere, and the part within the designated area of Hemel Hempstead New Town, which went to Dacorum.

The new district was named "Three Rivers", referencing the rivers Chess, Colne, and Gade which flow through the district and have their confluence in Rickmansworth, the largest town in the district.

Governance
Hertfordshire has a two-tier structure of local government, with the ten district councils (including Three Rivers District Council) providing district-level services, and Hertfordshire County Council providing county-level services. In some areas there is an additional third tier of civil parishes.

Premises
The council's main offices are at Three Rivers House on Northway in the centre of Rickmansworth, which was purpose-built for the council in 1991.

Elections
Since the last boundary changes in 2014 the council has comprised 39 councillors representing 13 wards, each of which elects three councillors. Elections are held three years out of every four, electing one councillor from each ward each time.

Parliament
For parliamentary elections, the district is divided across three constituencies. Most of the district is within the South West Hertfordshire constituency, which is considered a safe Conservative seat and held by a Conservative MP (currently Gagan Mohindra) since its creation in 1950. The eastern parts of the constituency, to the north and south of Watford, are part of that borough's constituency, which is a three-way marginal currently held by Conservative Dean Russell, having fluctuated between Labour and the Conservatives. Parts of two wards, north of the M25, are in the St Albans constituency, which is currently held by the Liberal Democrat Daisy Cooper.
