| The Average Streamflow Index, plotted as the red line on the above graphs, is calculated each day as the average of the streamflow index values for all the stream gaging stations in the state or water resource region having at least 30 years of record |
| The streamflow index value at a station compares the real-time measured flow value to historical values for the current day of the year. |
| For more insight into the meaning of this index value and to review how many streamgaging stations have flows occurring in each of the seven streamflow index categories, follow the link to the table below. |
|
Important Note: Gaps in the red line occur on days when less than two-thirds of the maximum number of stations in the state report data. On these days, confidence in the plot value is substantially reduced, and may evenmisrepresent actual conditions. To avoid potential bias in the presentation, no value isplotted for these days. The loss of data is usually related to equipment failure, computer problems, or telecommunications difficulties. Occasionally, widespread flooding events can disrupt data acquisition at a large number of stations. |
