MARQUEZ GARCIA, Antonio Zoilo; CALVA BENITEZ, Laura Georgina  y  PEREZ ROJAS, Alberto. Bathimetric considerations of the Carretas-Pereyra lagoon system, Chiapas, Mexico. Hidrobiológica [online]. 2006, vol.16, n.2, pp.121-125. ISSN 0188-8897.

The depth of the Carretas-Pereyra lagoon system was monitorei by a ruler in five stations during the period between the year 1998 to 2003. The results showed a severe varation of the depth for the year 1998 caused by high pluvial precipitations ocurred in september 1998 that produced a refill of the Pereyra and Bobo Lagoon, and a depth increment to 2 m approximately for Carretas lagoon's mouth and 1.80 m for Bobo lagoon. Between the years 2000 and 2001, the lagoon system showed a paulatine decrease of the depth up to less than 50 cm as a results of lower precipitations with movements of sediments inside the lagoon. From the year 2002 to 2003, it established again a cyclic behaviour of the lagoon's depth with near one meter of depth during the rainy season and half of a meter in dry season.
