We also experienced intense heat in here and I think it is officially started the summer season. The water level at the river keeps lowing and yes this is very sad My friend.
On the other hand, It looks like the place is quite very strict because of the checkpoints in the place.
The water is very stinky in places and full of algae because it is so shallow and the weather so hot. Here the rains have already returned, but only brief sprinkles once or twice a week. We tend to get the first rains up here in the mountains a few months before the rest of the country.
