Water Level Statistics

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
135.82	133.26	132.33	1996-08-07	2026-04-07	91	29.7	132.45	76.923
Statistics Calculated 2026-05-16

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	134.14	134.02	133.00	132.75	132.55	132.35	132.34	14	14
Apr	134.81	134.65	133.83	133.10	132.53	132.34	132.33	12	12
Jul	135.42	135.24	134.72	134.05	133.20	132.95	132.89	12	12
