Flood control project

In mid 2018, the United States Army Corps of Engineers announced it would be undertaking a major flood control project of the river, with a budget of $82.9 million.[4]

In mid 2021, funding was appropriated for work on the Río Grande de Arecibo, including work to improve the natural habitat of local species, including the Puerto Rican crested toad and a Río Grande de Arecibo canalization project was set to begin in 2023.[5][6]
