What this means

Low water at Rio Jacaguas above Lago Guayabal: the gauge reads 4.16 ft, far below normal for mid-October.

That puts it 0.65 ft below the median of 4.81 ft for mid-October, based on 14 years of readings. A year ago it stood at 4.44 ft (−0.28 ft).

The level has held steady over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 4.01 ft – 4.65 ft.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that.
