This report deals with geological work carried out in connection with the proposed dam at Hargeisa between october 1954 and may 1955

In 1954, the Government of Somaliland protectorate requested the Tanganyika Government to loan the services of an Engineer in water development in order to advise on matter of a water supply to the capital town of Hargeisa. The author of this report accordingly arrived in Hargeisa for this purpose on 23 September 1954 and after studying the problem, departed again on 6 October 1954. Specific recomendations were made before departure in terms of letter no 5/40/37 of 5 october 1954 to the Hon. the chief secretary to the Government and these recomendations are now embodied in detail in this report

An attempt has been made in this Report to describe the general geography of the Somaliland Protectorate from existing know1edge and from the results of a seven-year General Survey(1944-1950). Special attention has been paid to those aspects of geography that had not previously been sufficiently studied by research workers in the Protectorate (e.g. Time, Topography, Meteorology, General Geology, and the Ecology of nomadic stock-herding tribesmen). It is hoped that the factual material contained in the document will be of value for reference purposes to all interested in the Protectorate, of use in planning positive development and in preventing expenditure on uneconomic developmental schemes.
