(Veracruz) are situated on the banks of the Papaloapan. In the past the Papaloapan river basin was subject to frequent flooding, with the damage sometimes compounded by cyclones. A particularly severe flood in September 1944 covered , with great loss of life and property. The Miguel Alemán Dam on the Tonto river reduced the problem, but further floods occurred after it had been completed in 1955. A flood in 1958 covered and one in 1969 covered . Meanwhile, the drainage capacity of the Papaloapan river was being reduced by silt carried by the Santo Domingo river. Construction of the Cerro de Oro Dam in 1989 on the Santo Domingo river reduced the extent of floods to a manageable level. The states of Oaxaca and Veracruz are cooperating in developing the river basin. Plans include irrigation to improve agricultural production, promotion of forestry and fish farming and improvements to roads and river navigation. The planned projects will be designed to avoid ecological damage. Environmental damage has been the subject of considerable study.Patrick H.
