The stream gages show real-time observations of stream height and discharge. USGS compiles these measurements hourly. The rain gages provide information about precipitation totals in the last week.

As needed during rain events, staff controls the flood control facilities when river elevations near operating level, or the trigger elevation.

Please note, some gages may be reporting incorrect values. Staff is monitoring the real current elevations of each stream. The best way to view real-time elevation data is through the Cameras page.
