Plot Description:

This page presents a sphagetti plot of river stage and forecasts. The plot is roughly centered on the date of your choice with the plot showing any forecasts made three days prior to the date and for one day afterwards. Sorry that you have to know the station ID prior to using this page (will fix at some point). Presented timestamps are hopefully all in the local timezone of the reporting station. If you download the data, the timestamps are all in UTC.

For the image format output options, you can optionally control if forecasts, observations, or both are plotted. For the Interactive Chart version, this is controlled by clicking on the legend items which will hide and show the various lines.

A Download Portal is available to more easily download the raw data in bulk.
