  1. not much change in the Ogallala levels in Nebraska, especially in contrast to other states. got any idea why that is? ie, more adequate recharge, surface topography of the underlying formation, or what?

    1. Well, certainly sand makes for good recharge. Nebraska was blessed with a major portion of the aquifer. For example, in parts of Kansas it's quite shallow.

    2. i forgot about that sand thing...and if it's deeper in Nebraska, then groundwater will tend to flow downhill to there from Kansas...still, it's the top of the water level that's getting lower in the south, and i'd tend to think that would equalize over time...but that little graphic in the article shows that even as the water level has gone down 100 to 150 feet in parts of Kansas, it has actually gone up 10 to 20 feet in parts of Nebraska...that suggests there's not much continuity between the states. and that any water movement within the aquifer is at a snail's pace...

    3. Quote:
      Although the average saturated thickness is about 60 meters (200 feet), it exceeds 300 meters (1,000 feet) in west-central Nebraska and is only one-tenth that in much of western Texas. Because both the saturated thickness and the areal extent of the Ogallala Aquifer is greater in Nebraska, the state accounts for two-thirds of the volume of Ogallala groundwater, followed by Texas and Kansas, each with about 10 percent.

      Needless to say, Nebraska also takes the most of the Ogallala fossil water out for irrigation of corn - to make ethanol or export beef.
