Traditional vs Megawatershed Model


• Assumed mountains are solid.  All precipitation runs off mountains

• Most groundwater is found in shallow subsurface basin aquifers

• Shallow aquifer recharge is from mountain runoff and local precipitation

Groundwater found in fractures is local, poorly recharged or “fossil” 


• Actually, mountains are fractured and leak.  High percentage of precipitation infiltrates into pervasive fracture systems and under adjacent basins

• Mountain precipitation is seldom measured and vastly underestimated

Water flows long distances from mountain rainfall through fractures in Earth’s crust to deep ocean discharge and desert evaporation
