Origin

The name Río Matilde has sometimes been used to refer to a segment of Río Pastillo,[3][note 1] but Río Matilde actually results from the confluence of Río Pastillo and Río Canas.[4] Río Pastillo joins from its easterly run in the western section of the municipality of Ponce, while Río Canas joins from its southerly run in the northwestern area of the municipality of Ponce, both merging to form Río Matilde at their confluence in Barrio Canas just west of Urbanizacion Rio Canas and north of PR-2 in Ponce.

At 1.7 kilometers (1.1 mi) long, Río Matilde is the shortest river in the municipality of Ponce. The river is approximately one mile long and empties into the Caribbean Sea at 17°58'55"N, 66°38'16"W in the area of Los Meros in Barrio Playa.[4][5]

Canalization

The Government of Puerto Rico has plans to canalize this river.[6]

Notes
  1. Rio Matilde has sometimes been erroneously called Río Pastillo. In particular a segment of that river (Río Pastillo) that flows into Río Matilde has been called Río Matilde. For example HERE (Informe Ecologico de Flora y Fauna, Proyecto Gasoducto del Sur: Peñuelas, Ponce, Juana Díaz, Santa Isabel, Salinas. For: Proyecto Gasoducto del Sur - Peñuelas, Ponce, Juana Díaz, Santa Isabel, Salinas. By: ENSR (Piscatway, NJ) - AEE (Autoridad de Energia Electrica). Page 19. Retrieved 26 November 2013.) states "Río Matilde: ... Hacia el Norte desde su intersección con la Quebrada del Agua se le conoce como Río Pastillo." Translated and paraphased: North of its intersection with Quebrada del Agua creek, Rio Matilde is known as Río Pastillo.
