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 10.51 5.06 1.52 2001-10-05 2026-03-31 291 24.4 2.89 83.3 Statistics Calculated 2026-04-07 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 6.60 6.18 4.99 4.25 3.79 2.80 2.31 24 24 Feb 6.21 5.39 4.99 4.19 3.61 3.32 2.98 20 20 Mar 6.02 5.25 4.47 3.77 3.30 2.50 1.52 22 22 Apr 5.86 5.21 4.80 3.65 3.36 2.95 2.84 23 23 May 6.59 5.51 5.09 4.62 3.96 3.73 3.39 24 24 Jun 9.74 7.28 6.07 5.30 4.94 3.78 3.05 24 24 Jul 9.41 7.39 6.75 6.21 5.65 4.97 4.45 23 23 Aug 9.73 8.40 7.65 6.87 5.80 4.99 2.83 24 24 Sep 10.51 8.68 7.88 7.19 5.63 3.74 3.37 24 24 Oct 8.10 7.62 7.45 6.51 4.26 3.57 3.35 23 23 Nov 7.39 7.07 6.56 5.56 4.44 3.20 2.51 24 24 Dec 7.03 6.55 5.81 4.63 3.53 2.93 2.53 23 23 Statistics Calculated 2026-04-07 -
