Elsewhere in Praja there are posts on 'Killing Lakes' supported be excellent documentation.
With oodles of funds coming in from JNNURM, why can't Govt / BBMP / Zilla Panchayaths recharge the lakes from dying and create a source for collecting rain water when it pours? We have money pouring in from Delhi and soon it will be monsoon. Have they thought of reviving all our waterbodies in Bangalore ( even all over Karnataka) by consturcting suitable feeders and enbankments to collect water? Recharging our lakes by natural and artificial means is the best way so that we have canals, small lakes and tanks, wells etc and water is available for both drinking and agriculture in urban and rural areas.
On a priority , they should use JNNURM funds mainly for this.
