,the same Tamil nadu stopped the cleaning of Ponds and lakes in three districts of Karnataka which were near to Cauvey(not belonged to River) fearing that Karnataka may store river water there and create shortage.you know each and every village has pond or Lake and if it is not cleaned what will happen to villagers. Finally it was Karunanidhi who called Kannada people as Lingustic in public meeting and te whole world knows who are linguistic people. if they people feel kannadigs are linguistic then why cant they accept hindi as National Language.
