Three Rivers is a local government district in south-west Hertfordshire, England. Its council is based in Rickmansworth.

The district was formed on 1 April 1974, under the Local Government Act 1972, by the merger of Rickmansworth Urban District, Chorleywood Urban District and part of Watford Rural District. The confluence of the Chess and the Gade with the Colne in Rickmansworth inspired the district's name.[2]

District council

Further information: Three Rivers District Council elections

Three Rivers is a non-metropolitan district that elects one-third of its councillors every four years and with the fourth year for elections to Hertfordshire County Council. In the 2014 elections new ward boundaries came into effect and the council was reduced from 48 to 39 seats. All seats were contested at that election although future elections will continue to be conducted in thirds.

The Liberal Democrat administration fell to minority status with the resignation of two councillors from the party, in March and April 2018.[3][4]

Following the 2 May 2019 elections, the composition of the council is:

Party Councillors
Liberal Democrats 24
Conservative 12
Labour 3
Total 39


Three Rivers is composed of thirteen wards, each electing three councillors:

County council

For elections to Hertfordshire County Council, the district is divided into six divisions, three of which are held by the Conservatives, and three by the Liberal Democrats:

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.
