Why is water is such a contentious issue? Water is a scarce resource, especially in California where rainfall is so inconsistent. Compounding capricious hydrological cycles, the southern part of the state gets very little precipitation. This means that nearly all water must be pumped in from Northern California or the Colorado River. Controlling that water is big business. There seems to be an endless stream of litigation concerning water rights and the cost of transporting supplies. It’s important to remember that water is not only crucial for taking showers and doing dishes.
