E Change in Storage
Method used to calculate change in storage
The process for estimating the groundwater storage change from 2015 to 2019 was the same process utilized by all the GSAs in the basin in preparation of their GSPs and included the following steps: 1. The final wells selected from the water surface elevation review and contouring process were used to create depth to water surfaces, as described above. 2. Using the depth to water surfaces, the average depth to water value was determined for each unique specific yield unit. The average depth was determined using ArcGIS Spatial Analyst. 3. For each specific yield unit, the average depth to water of that area was used to determine the height of water above 400 feet for each depth zone. 4. The height of water in each depth zone was multiplied by the specific yield for that depth zone and then by the total acreage within that Specific Yield unit. 5. Values for each depth zone were added to determine total volume in storage above 400 feet. 6. The groundwater in storage volume by specific yield units were totaled by GSA to estimate the GSA total for that year. 7. Steps 1 through 6 were repeated for the ending year being considered. 8. The total volume in storage estimated for the starting year was subtracted from the total volume estimated for the ending year to determine the total change in volume between the two years.
