It takes 8 gallons of water to grow a tomato; 616 gallons to make a burger patty. In fact, the food each of us consumes per day represents an investment of 4,500 gallons of water, according to the California Farm Bureau. In this densely populated state where it rains only six months out of the year, where does all that water come from? This thoroughly engaging, concise book tells the story of California's most precious resource, tracing the journey of water in the state from the atmosphere to the snowpack to our faucets and foods. Along the way, we learn much about California itself as the book describes its rivers, lakes, wetlands, dams, and aqueducts and discusses the role of water in agriculture, the environment, and politics. Essential reading for a state facing the future with an already overextended water supply, this fascinating book shows that, for all Californians, every drop counts. * Features 137 color photographs and 27 color maps * Includes a table "Where Does Your Water Come From?" that answers the question for 315 California cities and towns * Provides up-to-date information on water quality in California, covering such timely topics as Giardia, groundwater contamination, fluoride, and the bottled-water phenomenon
