Karnataka has not been allowed to develop its basin area by unfair treaties in British Raj and also the interim award restricted it to 11.5 lakh hectares.
Yes karnataka has many small dams which have submerged lot of land. Besides many rivers take birth in western ghats and join immediately. The basin area in western ghats doesn't need irrigation and only plain areas are irrigated. so thats the reason in lesser basin area. But the total catchment are is more than 425 TMC which is abt 54%.
TN has one big dam (Mettur) & others small Bhavani Sagar, Vaigai, etc.Rest are Anicut which only distribute water. The water management system is old and ineffiecient which results in lot of wastage.It has been expanding its ayacut areas and also supporting three crops per year. This is what has made matters worse in already deficit river.
