Water Use In California
Water use in California is split between agriculture, fish, recreational, residential and industrial use. Agriculture gets most of the water, the farmers are given allotments that they have to use or lose what they did not use. Agriculture need for water varies from year to year depending on rain as well as the water supply.
One solution to the excess agricultural water is to allow the farmers to sell the excess water they don't need. The allotments should remain stable so that the farmers can use just the amount needed for the season.
