You are right, the Aluminium aerosol in Chemtrails is used in conjunction with HAARP to move clouds ( rain ) around. So they can create either floods or droughts in any area ,at will , to suit their objectives. In agricultural areas, where they want to stop cropping and livestock production, most often it will be drought. I often travel through rural areas where agriculture is the main industry, and there are chemtrails cris-crossing the sky - lots of them. They are sprayed there usually just before a weather front with rain comes across so they can push the clouds away. In your case, i guess the Chemtrails are sprayed to keep the rain there, not push it away.
