VOLTA
, the largest See also:river of the See also:coast of Upper See also:Guinea, between the See also:Gambia and the See also:Niger, with a length of about goo m
.
Its mouth and the greater See also:part of its course are in See also:British territory
.
Its See also:lower course had been known since the discoveries of the Portuguese, from whom it received (15th See also:century) its name on See also:account of the winding nature of its stream
.
It was not, however, until the last fifteen years of the loth century that the extent of its See also:basin—extending far See also:north within the See also:bend of the Niger- -was made known
.
There are two See also:main upper branches, the See also:Black and the See also: Both See also:rivers shrink greatly in the dry See also:season, reaching their lowest level at the end of See also:January . Below the junction the Volta flows S.E. and S., turning, however, E. for 4o m. just north of 6° . In 7° 37' N. it receives on the See also:left See also:bank a large tributary, the Oti, coming from 12° N . In its lower course, through the forest belt, the river has often a width of over See also:half a mile, with a See also:depth in places of .lo to 5o ft. in the rains, but in 6° 18' N. it traverses a pass in which its width is narrowed to 3o yds . Its use as a See also:water-way is limited by a number of rapids, the lowest of which occur in 6° 7' N., above the trading See also:port of Akuse . Its mouth is also obstructed during the greater part of the See also:year by a See also:bar . The river is usually navigable by small vessels from its mouth for about 6o m . The lower Volta was explored by M . J . See also:Bonnat in 1875, but the upper basin was first traversed by the See also:German traveller G . A . See also:Krause (1886–87) and the French See also:captain L . G . Binger (1888) . It has since been explored by a number of colonial officials—German, French and British . Between 6° 41' and 8° 8' N. the Volta forms the boundary between the Gold Coast and See also:Togoland . |
