GROUND WATER CONTROL & REGULATION Over-Exploited Taluka : Nil Critical Taluka : one Semi-critical Taluka six 15. MAJOR GROUND WATER PROBLEMS AND ISSUES The stage of ground water development in 6 talukas (Karad, Khatav, Koregaon, Phaltan, Man and Wai) has already crossed 70%. Most of these talukas fall in rain shadow zone of Western Ghats, where rainfall is low. Water logged area occurring in the command area of Nira right bank canal. The western part of the district has prominent hill ranges, isolated hillocks and undulating topography, which gives rise to very highr surface run-off. The underlying basalt formation has poor storage and transmission capability rendering the aquifer to limited potential. The unconfined aquifer gets fully recharged instantaneously and a situation of rejected recharge emerges. Also, the aquifer gets drained off quickly due to sloping and undulating topography.
