The objective of this research is to establish the frequency of significant amounts of natural recharge occurring from playa lakes following large precipitation events, and determines if the quantity is enough to discontinue artificial recharge studies.

Previous investigations of recharge, as well as the Soil Conservation Service method of computing runoff, are reviewed in Chapter 2. The method used to compute runoff from historical rainfall events is described in Chapter 3. The results of the analysis are presented in Chapter 4. Chapter 5 contains the conclusions, some observations regarding their importance, and recommendations resulting from the overall study.
