What this means

Gibraltar Dam Diversion Weir A Gibraltar Dam is running below normal at 17.80 ft.

It has barely moved over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. In the last month it has stayed between 17.78 ft and 17.81 ft.

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

Compared with 5 years of daily readings for this time of year. How to read levels
