The story behind it

The Cauto crosses a wide, hot plain covered with sugar cane, rice fields and grazing cattle. Long ago small ships sailed a good way upstream, but over the years soil washed down from the cleared hills and filled the bed with sand, so today only shallow boats can pass. The weather here swings between extremes: in the dry season parts of the riverbed shrink to puddles, while a single hurricane can send brown floodwater across whole villages. Near the coast the Cauto ends in a wide delta of mangroves, mudflats and salt lagoons where pink flamingos wade and manatees swim in the warm shallows. Farmers pump water onto their rice fields, fishers cast nets from the banks, and the old city of Bayamo lies not far from its middle course.
