Assignment 6 1-Evaluate the U.S. water budget, and identify critical aspects of present and future freshwater supplies. 2-Compare MD and CA in terms of main sources of water supply.    Identify the main sources of water supply for both MD and CA, respectively. Are there any desalination plants in MD or CA? What major dams are present in MD and CA, and what are their respective capacities?
