Reading these numbers
Readings are elevations in feet above the Puerto Rico Vertical Datum of 2002 (PRVD02), the island's official height reference. Older reservoir documents may use a local or meter-based reference, so check which one a ramp or intake elevation uses before comparing.
On a reservoir, a few feet of drop changes the shoreline more than you would think. Low water exposes stumps, sandbars and old roadbeds that are normally well under the hull, and some ramps end before the water does.
High water brings its own problems: floating debris after storms, flooded docks and courtesy piers, and no-wake rules near flooded campgrounds. A quick look at the trend before you hitch up saves a wasted trip.
The gauge is listed by USGS as Lago Patillas at Damsite near Patillas, PR. Wind can pile water up at one end of a big lake for a few hours, so short spikes on a windy day are normal.
