Tamil Nadu's 15 major irrigation reservoirs held about one-third of their combined capacity, compared with roughly 92% at the same time the previous year. Although seasonal rainfall had reached about 240 mm, the state needs substantially more rain, particularly in November, to support water supplies and rice production.
Low reservoir storage threatens irrigation in the Cauvery delta and could reduce Tamil Nadu's rice output if the monsoon fails to replenish supplies. A production shortfall would tighten local availability and put upward pressure on rice prices.
After 179 past bullish weather events, Rough Rice moved a median +0.4% over 5 sessions (55% higher; middle half -1.4% to +2.5%), and +2.2% over 20.
