Of the 110 gauges we track in Puerto Rico, 50 are low for this time of year and 4 are high. Low water clearly outweighs high water at the moment.
The main rivers covered are the Canal De Patillas, Canal De Riego De Lajas, Rio De La Plata and Rio Grande De Loiza. The list also includes one lake or reservoir. Fall is often a low point for rivers after the summer, until steady rain returns.
