This week locals in Boca de Tomatlán rose up again after the official CLOSED stamps placed on the unfinished dam site over the river Los Horocens by the administration of Vallarta in early 2019 were removed. This could mean the construction workers and heavy machinery are going to be back soon.
Three years ago, a private company arrived at the Los Horcones River, which runs through Boca de Tomatlán, and began constructing a dam using plastic explosives to remove giant rocks and cutting down trees.
This was worrying for the locals because this river contains so much water during the rainy season and low levels in dry months, so a dam would block its natural behavior and leave the zone without water. It would be especially damaging if the dam takes the water for resorts or other human consumption, as has happened in other local rivers.
Many protests were made, and finally, in early 2019, one resulted in the closing of the dam after someone exposed that work was started without the permission of Vallarta authorities, only the authorization of the Cabo Corrientes municipality. The dam is being built between two separate state territories.
River Los Horcones is extremely important to regulate the temperature in the bay and is one of the last clean-water rivers with a constant flow of water in the region.
A petition in Change.org is demanding the federal government grant a declaration of National Protected Area for Los Horcones River and canyon, so legally, no one would construct anything there.
With over 600,000 signatures, the government has not heard the petition, and the river is once again in danger.
The Vallarta government told the local press that a federal judge ordered the stamps removed after the company responsible for the dam went to court and won.
If work starts again, the activists will protest against the dam like they did back in 2018 to protect the environment of Puerto Vallarta, which has been significantly damaged by other unstopped projects.
