The Grijalva - Ron Canter

Ron Canter continues his study of Maya watersheds with an important article on the Grijalva River, which begins near the Guatemala border, winds through the States of Chiapas, and Tabasco, to join with the Usumacinta and empty into the Gulf of Mexico. It has long since been exploited for hydroelectric power, drowning innumerable and now unknowable ancient settlements. It is a hint of what could happen if the Usumacinta dams are ever built.

Ron's full article can be read by clicking "More". The photo above shows the Grijalva, at the site of San Isidro, in 1981 as the river is rising due to new dams.

Cleaning up the Usumacinta

5 million pesos does not seem like much to clean up pollution and trash in the river, but it's better than nothing. The Usumacinta drains an enormous area of Guatemala and Mexico, getting contamination from trash and agricultural chemicals along the way.

Lake Atitlan, Ecological disaster

Friend ALonso Mendez just sent a dispatch from Lake Atitlan, Guatemala, where in the last 20 days an enormous "algae bloom" (actuallu mats of cyanobacteria) has covered much of the lake. It is a problem that has been coming for a long time, due to human sewage problems and neglect and corruption among the officials charged with improving the treatment plants.

Higher res Usumacinta, Google Earth

Thanks to Charles Golden for pointing out the new, higher resolution imaging of the Usumacinta watershed in Google Earth. Downside? You can see clearly the extent of the deforestation around the Yaxchilan oxbow in the Sierra del Lacandon Park on the Guatemalan side.

Usumacinta Oil Rig Disaster lawsuits

Lawsuits against four companies, including Halliburton. This article has a good description of what happened, and the plaintiff's claims of why it happened - faulty consulting as to the condition of the seabed in the area the rig was installed.
