The stunning ruin of the 16th century structure has been hidden under 100ft of water since 1966. The church dates back to 1564 when it was built in anticipation of a population increase, but when the plague struck between 1773 and 1776, the church was left abandoned.
Architect Carlos Navarettes commented on the building, saying: ‘It was a church built thinking that this could be a great population centre, but it never achieved that. It probably never even had a dedicated priest, only receiving visits from those from Tecpatán.’
A previous sighting of the church came in 2002 and the water levels in the reservoir became so low that visitors were able to walk inside it. Fishermen have been taking passengers out to the ruins to get a look, explore, and even climb its walls.
The church disappeared in 1966 when the hydroelectric dam was built in the Grijalava River.
So what actually goes into monitoring a reservoir’s water?
Reservoirs actually require a lot of different monitors; for instance, a reservoir needs pH, turbidity and dissolved oxygen monitors and so keeping an eye on all of them can be quite time consuming. The Partech 7300w² Monitor is designed to watch them all simultaneously.
