During May 2016, the NRD measured over 500 observation wells throughout the District and then averaged the data of all these wells. Observation wells are measured in the spring of each year, allowing the water table to rebound from the previous irrigation season. The observation wells measured are equally distributed geographically throughout the District to provide an accurate profile of the District average.
Overall, the spring 2016 average measurement for the groundwater level change shows a rise of 1.2 feet from last spring. The findings show that the spring 2016 average groundwater level is 3.55 feet above the “Allocation Trigger”. As a result, there will be no allocation restrictions for the 2017 irrigation season.
The District goal is to hold the average groundwater level to above the 1978 level. In 2005, the District average groundwater level reached the “Reporting Trigger” initiating groundwater users to report annual groundwater use to the District and to certify their irrigated acres. If the District average level falls below the 1978 level (“Allocation Trigger”), groundwater allocation will begin.
