The measure, called the “Gaining Responsibility on Water Act” or GROW Act, has already passed the US House, largely along party lines. Supporters, including many Central Valley Republicans and farmers, say it would cut the red tape that prevents dams and water storage projects from being built. While that might normally sit well with powerful Southern California water interests, this bill is unlikely to garner support from the Metropolitan Water District of Southern California. General Manager Jeffrey Kightlinger says the measure doesn’t strike the right balance between water supply and the environment.
