The lagoon used to have a lot of water. Unfortunately, it is now used to irrigate the surrounding truffle plantations that were established a few years ago. As a result, the water level continues to drop. Pretty sad when you know what it looked like there before. The lack of rain is also making things worse. When the sun goes down, it looks very beautiful there. Red earth and sometimes Caribbean blue water.
