Open the enhanced chart
From the station chart, click on the enhanced view button, which will launch a full-screen chart in separate browser tab. The regular view remains open in the original browser tab so that you can easily return to it.
Interpret the chart's data
Solid black line: daily historical recorded (actual) river level up to yesterday.
Light blue lines: daily min/max values recorded data.
Dark gray dashed line: forecasted river level value for next 28 days.
Light gray dashed lines: probabilistic forecast confidence envelope for next 16 days.
Click and the screen to the right to move backward in time. Data will load as you go.
Double-click on either the X or Y axis to rescale it. Click and hold on either axis to manually rescale the axis.
Change display options
Similar to the station chart, the enhanced chart also allows you to change the station that you're viewing, select an aggregation period, choose whether or not to display the High/Low range (actual and forecast), view historical forecasts, and create alerts.
