Catchment Board
River boards were authorities who controlled land drainage, fisheries and river pollution and had other functions relating to rivers, streams and inland waters in England and Wales between 1950 and 1965. Background Prior to the 1930s, land drainage in the United Kingdom was regulated by the Statute of Sewers, passed by King Henry VIII in 1531, and several further acts which built upon that foundation.

A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground.
