As a matter fact this Tail Pond Dam should have been completed by 1990, but despite having been given all the necessary permissions only because of the sheer negligence the delaying tactics that the construction of tail pond has been abnormally delayed, because of absence of tail pond, during the generation of power whatever water is used is being sent down the stream without storing for re-use. The left out water is reaching the Prakasham barrage; from there that water is being supplied to peasants of Krishna district for decades on. Thus the water which was supposed to be supplied to Telangana Region is being diverted to the Andhra region for decades together.
