The graph has color-coded stream levels by flood category: Action, Minor, Moderate, and Major. In the purple-shaded ‘Major Flooding’ graph portion, a #212121 line and ‘Record’ feet amount is the highest recorded flood level.
The top and bottom axes denote stream observation and forecast dates and times. The axis on the left side shows stream stage in feet. The right axis shows the stream flow in 1,000s of cubic feet per second.
The bright blue graph diamonds are the recorded stream levels. When staked on top of each other, they form a solid line. The red-purple squares are the forecast stream levels. Clicking on the diamonds or squares will open a table of recorded and forecast stream levels and flows. The recorded data are updated every 30 minutes. The forecasted levels and flows are in 6-hour increments. Both are listed in UTC time, Universal Coordinated Time or Greenwich Mean Time. Subtract 5 hours for Central Daylight Time in the summer or 6 hours for Central Standard Time in the winter.
