For flood control purposes, in the 1970s Río Portugués was diverted by the U.S. Corps of Engineers from emptying directly into the
Caribbean Sea at
Playa de Ponce to feeding into the Río Bucaná which then empties into the Caribbean Sea. This channelization project started in 1974 and was completed in 1997. It was a multimillion-dollar investment, with just the first phase costing $120 million.
Former course The former course of Río Portugués, prior to being diverted and channelized by the U.S. Corps of Engineers in the 1970s, followed from the area just north of
Avenida Las Américas/
PR-163 in a south-southwesterly fashion crossing Avenida Las Américas immediately east of
Hospital Dr. Pila. It then continued south behind the Governmental Center/
Puerto Rico Police Ponce Area headquarters, and followed a trajectory almost parallel to Avenida Hostos (
PR-123, formerly
PR-10). It then crossed
PR-2 immediately east of the intersection of Avenida Hostos and Ponce Bypass/PR-2, at the sector called "Caracoles". From there the river used to continue flowing southerly, at one point just edging the area where
Plaza del Caribe now stands. This old course then took a sharp westerly turn and crossed Avenida Hostos, at the now historic
Puente Río Portugués. From this point it continued running south-southwesterly where it (now, since the newly built
PR-52) crossed
PR-52. From here the river flowed another one mile (1.6 km) crossing the low-lying area of Barrio
La Playa at Avenida Padre Noel before draining into the Caribbean Sea about 30 or 40 yards from Avenida Padre Noel, in the area called
Villa Pesquera.
Current course ) in Barrio
Maraguez, heading South-bound. The Río Portugués canal is visible in the background as it empties into the
Caribbean Sea. Once the U.S. Corps of Engineers canalized Río Portugués as it flowed through the city of Ponce, the Corps also diverted its course from a south-southwesterly course to a south-southeasterly course. This diversion started immediately south of the river's intersection with Avenida Las Américas. From Avenida Las Américas the river now flows, channelized, in a south-southeasterly after crossing Avenida Las Américas about a quarter of a mile east of
Hospital Dr. Pila. After crossing Avenida Las Américas in downtown Ponce, the river comes to the location where in the 1970s it was diverted by the US Corps of Engineers from a southwesterly path to its current southeasterly path. Taking a sharp easterly turn, Río Portugués enters barrio
San Antón, and crosses route
PR-12/Avenida Malecon about one quarter of a mile north of PR-12's intersection with
PR-2. Shortly thereafter the river bends to become southbound and crosses route PR-2, about one quarter of a mile east of PR-2's intersection with PR-12. The river then borders the
Julio Enrique Monagas Family Park on the park's western edge until, still canalized, it feeds into Bucaná River about half a mile south of PR-2. The point where Río Portugués feeds into Río Bucaná is about one quarter of a mile north of PR-52 (a.k.a., Autopista Luis A. Ferré) and can be seen from the southbound side of PR-52.
Bucaná River After this point Río Portugués is no longer called Río Portugués. It becomes Río Bucaná (Bucaná River) and divides barrios
Playa on its western bank and barrio
Bucaná on its eastern bank. From there the river continues flowing in southerly course as a single canalized river for half-mile, crossing Autopista Luis A. Ferré/
PR-52. Another one mile (1.6 km) of southerly flow and the river empties as a single stream into the Caribbean Sea just east of
La Guancha, safely avoiding most low-laying populated areas. ==Uses==
