This is wrong information. This article contains erroneous information, to try to provoke a negative impression at international level on what is happening in the Nicaraguan San Juan river. Nicaragua Government is conducting a dredging in the San Juan River covered in the judgement of the International Court of Justice (Haya) which gives full and sovereignty over the river and its islands. Costa Ricans only have the right of navigation. Costa Rica border begins on the right bank of the River in navigable State, so the army Nicaragua is located in territory nicaraguense.
If either set the map more closer to reality (Bing's) displays River as the border between the two countries, the nicaraguan army is located on a small island in the san Juan River, so never crossed into territory of Costa Rica.
So there hasen't been such thing as a INVATION.
Side inside bar, facing the lagoon of Harbour Head is landmark, a sort of almost two meters which is discovered in the midst of a coconut palizada concrete Obelisk.
This landmark, the same as the milestone 1 is 300 metres from the sea, were placed decades ago and are confirmation of the dividing line, which according to treaty Jerez - Cañas and paths Cleveland and Alexander Awards century and a half ago, continues along the lagoon of Harbour Head until the first barrel then continues towards the South Bank of the San Juan River.
Provisional army Nicaragua base is 300 meters North of the Obelisk on the sand stretches for two kilometres and joins the drain to the sea of the San Juan River bar.
There remains hoisted the blue and white flag of the country. The lagoon of Harbour Head is a body of Virgin water, surrounded by trees, where some fishermen of San Juan of Nicaragua arrive.
By the southern edge of the Lake, beside the tico, looming palizada coconuts and a few ranches that these days are uninhabited. Along that edge of the lagoon becomes the first pipeline which speaking Awards Cleveland, written by engineer Alexander, century and a half ago, and served to define the border between the two countries.
At that point rises another flag blue and white. Other times, assumes that spout was going to give directly to the San Juan River, and then from there, up to several miles before the Castle, the right side of San Juan in navigable State, mark the border. However, constant silting of decades would have covered much of the spout that now with the dredger is expected to recover to restore the real dividing line.
At the entrance of the spout is Frot trees, the same as the output. He is estimated that approximately 800 metres will be cleaned to restore that spout, according to what you said Edén Pastora, responsible for dredging project.
Cord Frot, trees so far, covers an area of more than fifty meters. That is what Costa Rica has denounced as environmental damage to its territory, however, according to the landmark, Nicaraguan territory. Environmental impact study that allotted the Ministry of natural resources and environment (Marena) said that the effects are minimal.
