Kalma (Chhattisgarh): Activists and members of Mahanadi Bachao Andolan Thursday visited the Kalma Barrage in Chhattisgarh, staged a protest and attempted to dismantle the sand embankment constructed over the barrage downstream, highlighting the serious concerns over restricted water flow in the Mahanadi. The team, led by the outfit’s convenor Sudarshan Das, marched from Kanaktora near Odisha border to the Kalma Barrage in the morning. They expressed serious concern after noting that even the limited water released through the open gate was being blocked by a sand embankment. Das said the protest was aimed at drawing attention to the worsening inter-state water dispute between Odisha and Chhattisgarh. The protest saw participation from social activists, river conservationists and farmer leaders from both Odisha and Chhattisgarh.
