And the Ogallala's sand and gravel composition slowed the downward flow of surface waters to refill it, even in wet seasons. Depending on geologic and hydrologic conditions of the aquifer, the impact on the level of the water table can be short-lived or last for decades, and it can fall a small amount or many hundreds of feet. 4 Because this aquifer is located within the larger High Plains Aquifer, the possibility of contamination is especially significant. In the High Plains Aquifer, of which the Ogallala is part, “there’s not a freshwater resource deeper” for farmers to drill down into, says Dennehy. It is a major source of irrigation water throughout the region. Click to see full answer.
