"The team then conducted digs in Belize’s Crooked Tree wildlife sanctuary. The ancient canals, paired with holding ponds, were used to channel and catch freshwater species such as catfish.
archaeologists have discovered a 4,000-year-old network of earthen canals in what’s now Belize. The findings were published on Friday in the journal Science Advances."

running for several miles through wetlands,
said study co-author Eleanor Harrison-Buck of the University of New Hampshire."

"The canal networks were built as early as 4,000 years ago by semi-nomadic people in the Yucatán coastal plain.
According to the study, the canals were used for about 1,000 years or longer,
including during the “formative” period when the Maya began to settle in permanent farming villages and a
distinctive culture started to emerge."
