Thoubal district is synonymous with a triangular shaped valley that occupies more than half of the eastern region of the state. The district encompasses an area of 517 sq. km and stretches between the latitudinal parallels extending between 23° 45' North and 24°45' North and the longitudinal meridians of 93°45' East and 94°15' East.
The district is enclosed between the districts of Imphal, Chandel, Ukhrul, Churchandpur and Bishnupur and is sited at an elevated altitude of 790 m above mean sea level.
The topography is a wonderful medley of hills and knolls as well as undulating plains that are laced by several rivers and dotted by sylvan lakes that gleam like a mirage of quicksilver. The district is drained by the Imphal and Thoubal rivers while the Kharung, Ikop,Waithou, Pumlen, Lousi and Ngangou Lakes shimmer prettily and adorn the landscape like a jewel in a brass setting.
