Riparian water rights (or simply riparian rights) is a system of allocating water among those who possess land about its source. It has its origins in English
common law. It is used in the
United Kingdom and states in the eastern
United States.Under the riparian principle, all landowners whose property is adjacent to a body of water have the right to make reasonable use of it. If there is not enough water to satisfy all users, allotments are generally fixed in proportion to frontage on the water source. These rights cannot be sold or transferred other than with the adjoining land, and water cannot be transferred out of the
watershed.
