River Flow/Level Graphs

raphs show stage (measured in feet) and flow (in cubic feet per second).

Seven-day graphs show data that is updated every hour (approximately). Thirty-day and one-year graphs are based on twice-a-day readings. The tick marks for each day indicate the start of that day (12:01 a.m.).

Some graphs show a green line representing the average flow or stage on that date, as taken from many years of data.
