The indigenous Boruca language name is Diquís which means "great river". Its basin is 5,085 square kilometres and it is 160 kilometres long, covering ten percent of the country. It is a tributary from the confluence of the Río General and Río Coto Brus. Pineapple plantations occupy 10,815 hectares in the basin, amounting to 21 percent of national production. Mangrove cockles (Anadara tuberculosa and Anadara similis) known locally as piangua are collected in the mangrove swamps and mud at the mouth of the Río Grande de Térraba. It is anticipated that the proposed Diquís Hydroelectric Project will cover 6,000 hectares and will require the relocation of 1,100 people.
