The river's flow is influenced by precipitation and runoff from the surrounding mountains, as well as groundwater discharge. The river has several tributaries, including the Rio Tanama and Rio Dos Bocas, and is impounded by several dams, including the Dos Bocas Dam. Seasonal trends in river flow are influenced by the rainy season, which typically runs from May to November, and the dry season, which runs from December to April. Interesting facts about the hydrology of the Rio Grande de Arecibo include the presence of caves and sinkholes in the surrounding karst landscape, which can affect the flow of groundwater to the river.
