P.R. Laws tit. 22, § 178
No provision contained in this chapter shall in any way affect the right to the use of water granted by the Puerto Rico Southern Coast Irrigation Service Act to the lands served by the Puerto Rico Public Irrigation Service, South Coast, §§ 251—279 of this title, nor the rights of water concessions of the Jacaguas and Toa Vaca Rivers conferred by the Spanish Crown which were not granted or conveyed to the People of Puerto Rico and which are still in force, as legally recognized, and said lands shall continue to enjoy the benefit of those waters in the same degree and to the same extent as they do at present. The Toa Vaca Dam and Reservoir shall be subject to the obligation existing toward the lands being irrigated by waters from the Guayabal Reservoir and for such purposes the Puerto Rico Aqueduct and Sewer Authority shall deliver the waters from the Toa Vaca Dam and Reservoir appurtenant to the Southern Coast Irrigation Service, allowing them to pass from said dam to the Guayabal Reservoir, according to the need of said irrigation service. If the estimated average water capacity of twenty-three million (23,000,000) gallons daily of this first stage, which in addition to the supply now regulated in the Guayabal Dam is expected to be used upon construction of the Toa Vaca Dam and Reservoir, the Southern Coast Irrigation Service shall retain for its own use the remaining waters after deducting the amount of nine million (9,000,000) gallons of water daily which is hereby allocated and made available to the Aqueduct and Sewer Authority for industrial and municipal (residential and commercial) purposes in the southern-central region of Puerto Rico.
