The corporation says Letsibogo Dam is currently at 40 percent from last year's 86 percent during the same period. "Apart from supplying greater Gaborone (areas surrounding Gaborone) with 36 percent of its water, the dam is also responsible for supplying the BCL mine, Mmadinare, Palapye and Mahalapye areas," the corporation states. At its current level, WUC says, Letsibogo Dam can only supply its catchment areas for 12 months without any inflow.
Bokaa Dam, on the other hand, registered a decline of 46 percent; recording 61 percent and 15 percent in 2011 and 2012 respectively during the same period. This translates to three months of supply without inflow. Bokaa Dam contributes 25 percent of its water to greater Gaborone. Nnywane Dam, which supplies Lobatse, is at 52 percent and can supply water for only eight months without inflow. The corporation reveals that Gaborone Dam stands at 56 percent and can supply water for 20 months without inflow. Only two dams, Shashe and Ntimbale currently have satisfactory levels at 87 percent and 90 percent respectively. Shashe Dam supplies greater Francistown (Francistown, Tonota, Mathangwane, Matshelagabedi, Matsiloje, Tati Nickel and Mopani Mines) while Ntimbale Dam services the North East and Tutume districts with 50 percent of its water. The area gets another 50 percent from Maitengwe wells.
