Summary
Summary reservoir elevation (Observations at 2400 hours) statistics based on the user defined analysis period, for each calendar day in a year.
For each calendar day, the percentage of days in your analysis period when daily reservoir elevation was between — and — feet.
25th / 50th / 75th percentile reservoir elevation, graphed for your future dates of interest, based on your analysis period. Future window: —. The normal reservoir elevation range is defined as reservoir elevations between the 25th and 75th percentile.
25th / 50th / 75th percentile reservoir elevation, graphed alongside actual daily reservoir elevation for your comparison dates, based on your analysis period. Compare window: —.
Daily water surface elevation for every year in your analysis period (grey), with the current year in red. Point at a line, or at a year listed below the chart, to highlight it; click to pin it.
Only daily values inside the user defined analysis period are drawn in grey, so the first and last years may be partial (shown in italics). The current year is drawn in full. Breaks in a line are days with no record.
