The chart plots where the water level sits inside the range this reservoir has recorded since 1990 (891.92 m to 903.07 m). It is a level position, not a share of storage capacity — Puerto Rico does not publish reservoir volume.

Design capacity is the volume the dam was built to impound, from the US Army Corps of Engineers' National Inventory of Dams. It describes the size of the reservoir — it is not used to compute a fill percentage, because the elevation-to-volume curve needed for that is not published for Puerto Rico.
