South Tongu, with Sogakofe as its capital, is one of the Volta Regions 18 districts. It shares boundaries with the North Tongu District to the north and north-west, the Akatsi District to the northeast, Keta Municipal to the south and the Dangbe-East District to the west and southwest. The main river draining the district is the Volta, which runs along its western border, but it is also drained by numerous streams, prominent among them being the Chinni and Todzi, with a large number of lagoons in the southern sector of the district.
The district lies within the wet semi-equatorial and dry equatorial climatic zones, which are very good for livestock production. The coastal strip is covered by swamp and mangrove vegetation. South Tongu had an estimated population of 87,766 as at 1994 and this is growing by some 2.5% per annum. This is faster than the regional growth rate of two percent but lower than the national one of three percent.
District Chief Executive for the South Tongu District, Daniel K. Amelorku has hinted of plans to construct accommodation facilities for security personnel in some new communities that the assembly is putting up new police stations.
