What this means

At 4.23 ft, the Quebrada Grande at Bo. Dos Bocas is below normal for mid-October.

That puts it 0.15 ft below the median of 4.38 ft for mid-October, based on 25 years of readings. It is 6.77 ft below the flood stage of 11.00 ft. A year ago it stood at 4.22 ft (+0.01 ft).

The level is falling, down 0.37 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. Over the past 30 days it has moved between 3.82 ft and 5.07 ft.

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

What the stage means on the water

Low water means more dragging on shallow riffles and slower floats. Fish crowd into the deeper runs, and warm, low water stresses them, so play and release them quickly.

The National Weather Service puts flood stage for this gauge at 11.00 ft, still 6.77 ft away.
