  1. Travis Macha Preserving the Ogallala Aquifer: For Today and Tomorrow Texas Tech University

  2. Thesis • In the past, the Ogallala has been a seemingly infinite supply of water however, current research has put an end to that as indicators of declining water levels are prompting a reexamination of farming conditions as well as a range of irrigation strategies to meet conservation goals.

  3. Subtopic 1: Water Depletion • Take-away: However, depleting at rates that are still being disputed one thing for certain is water usage must slow to preserve the life of the aquifer for years to come. • Rate of decline • V.L. McGuire, Terrell and Johnson • Discussion on need for change in water usage • Terrell and Johnson, Hornbeck

  4. Subtopic 2: Irrigation Methods • Take-away: Modern irrigation techniques must be adopted as well as development of new ones for the overall goal of conserving the aquifer. • Need for adoption of modern methods, due to inefficient old technologies • Hornbeck, Keskin, Lamm and O’brian , • Call for development of technologies • Little, Lamm and O’brian , Verchick

  5. Subtopic 3: Farming techniques • Farming habits are also crucial to alter if conservation will succeed • Reliance on irrigation • Pfeiffer and Lin, Little • Using farming techniques to conserve water • Little, Castellazzi

  6. Conclusion • Current research indicates regardless of how fast, the Ogallala is depleting and it is the human responsibility to preserve it. • Not only must water efficient irrigation methods be used more wide spread but also farming methods must change. Low-tillage farming and crop rotations are excellent alternatives. • Continued research and adaption to the growing situation must continue to progress at a rapid pace to give the aquifer the best chance to be preserved.
