Cumulative groundwater recharge from all other sources in the Yadalavagu sub-basin was reached about 18.22 ha.m
which was contributed from non-command area as there is no groundwater recharge from other sources in command area in the Yadalavagu hydrological unit. Of this major amount of groundwater about 10.00 ha.m contributed by water conservation structures; 4.02 ha.m available from groundwater irrigation; 4.20 ha.m recharged by tanks and
ponds. In non-command area 9.20 and 9.02 hectares were recharged in monsoon and non-monsoon area respectively. 2.10 ha.m, 5.00 ha.m and 2.10 ha.m of groundwater formed as groundwater by groundwater irrigation, water conservation tanks and ponds and respectively in monsoon season. In non-monsoon season out of 9.02 ha.m, recharge from groundwater irrigation contributing 1.92 hectares; 5.00 hectares through water conservation structures and remaining 2.10 ha.m contributing from tanks and ponds (C. Bhuiyan, Ramesh P. et al, 2009).
