Recognizing the dour effect of climate change on the state's hydrology, Democrats in California's Senate have proposed using $7.5 billion in state and federal funds to "build a climate-resilient water system."Of those funds, $1.5 billion would be used to buy land with senior water rights from holders willing to sell them voluntarily in prioritized waters. The Democrats argue "fundamental changes" to the state's water system are "needed to realign demand, supply, and the flexibility of the system."
