How do we calculate statistics?
Overall Water Level Statistics (Depth to water, feet below land surface) Lowest Water Level Median Water Level Highest Water Level First Measurement Date Last Measurement Date Number of Measurements Years of Record Latest Value Latest Percentile 142.89 113.44 96.95 1988-11-08 2025-01-28 7580 36.2 96.96 100.0 Statistics Calculated 2025-04-22 Monthly Water Level Statistics (Depth to water, feet below land surface) Month Lowest Median 10th Percentile 25th Percentile 50th Percentile 75th Percentile 90th Percentile Highest Median Number of Measurements Years of Record Jan 139.94 137.48 135.98 113.16 100.93 98.51 97.16 24 24 Feb 137.36 137.13 135.83 116.56 102.31 98.91 97.88 25 25 Mar 142.89 136.80 134.57 113.97 101.12 98.74 97.57 23 23 Apr 136.57 136.51 133.32 112.36 100.6 98.31 97.38 22 22 May 136.54 136.33 135.56 113.62 100.9 98.29 97.09 23 23 Jun 137.31 136.52 134.61 113.44 100.3 98.13 97.43 21 21 Jul 137.72 136.85 135.84 111.91 100.84 98.37 97.82 22 22 Aug 137.58 137.17 136.16 115.50 101.65 98.82 97.80 25 25 Sep 137.74 137.42 136.34 112.92 101.16 98.84 97.83 23 23 Oct 141.46 137.78 136.77 112.71 101.26 98.89 97.79 23 23 Nov 137.99 137.22 135.62 113.83 101.35 99.06 97.58 24 24 Dec 137.96 137.42 135.12 110.84 100.72 98.68 97.47 22 22 Statistics Calculated 2025-04-22 -
