Its flow is mainly contributed by rainfall, and the constituents of the river include sediments, nutrients, and pollutants from agricultural and urban runoff. The river is fed by several tributaries, including the Rio Gurabo and Rio Caguitas. Seasonal trends in flow are heavily influenced by the tropical climate, with increased rainfall during the wet season from May to November. One interesting fact is that the Rio Grande de Loiza is home to a variety of aquatic species, including the endangered Puerto Rican coqui frog.
