Description

The declining water levels of the Las Vegas Valley aquifers and the half-empty Lake Mead are an issue of great concern. This project utilizes data from NASA and numerous other agencies for hydrogeological comparisons and calculations. Graphed results show similar trends between GRACE (Gravity Recovery and Climate Experiment) satellite data and the declining levels of Lake Mead. The observations of GRACE total water storage, precipitation, evapotranspiration and the net flux of water in the area all show a similar trending decline in yearly water accumulation, which may be indicators of the impact of drought and climate change in Southern Nevada.
