Abstract: Abstract Delta region of the Cauvery river in India is well known for paddy cultivation for centuries. Due to increased competition on river water sharing over the past century, availability and reliability of water in this region is dwindling. Changes in management practices, which caused the deterioration of traditional tank (relatively small reservoir) irrigation systems, and the difficulties in reviving them are discussed. Increasing the storage capacity of irrigation tanks for augmenting water availability for irrigation is discussed in detail. Managing the huge cost involved in deepening the heavily silted tanks in a sustainable manner is suggested through allowing mining activities in the tanks. Sample study on the suitability of soil for commercial uses indicates the possibility of mining in the tanks.
