The 2014-15 water year was the driest in the Kings River's recorded history, according to statement released Wednesday by the Kings River Water Association.
Records go back to 1895.
The association divvies out the river's runoff annually to 28 member agricultural districts, including several in Kings County. Deliveries to most of the districts have been slashed or eliminated as a result of the dry conditions.
Association Watermaster Steve Haugen said the runoff was 360,500 acre-feet, breaking the previous low of 391,000 acre-feet in 1923-24.
The association also reported that September 2015 is likely to go down as the river's driest month ever.
The 2014-15 water total would have been much lower if it hadn't been for an unusually large amount of thunderstorm rain in the Sierra over the summer.
The association reported that enhanced storm activity added approximately 100,000 acre-feet to the total.
An acre-foot is enough water to serve the needs of an average-sized U.S. home for 12-18 months, or enough to cover an acre of land to a depth of 16 inches.
