Last week, California offered to voluntarily cut its use of Colorado River water in exchange for federal money. California is the largest user of the river so the move could potentially reenergize negotiations among the seven states that rely on its water. POLITICO’s Annie Snider breaks down the impact of California’s proposed cuts, if the plan could actually help set the stage for a deal, and how the Biden administration might impact negotiations. Plus, the Environmental Protection Agency says lead emissions from small aircraft pose a threat, signaling the first step toward regulation.   Josh Siegel is an energy reporter for POLITICO.  Annie Snider covers water issues for POLITICO Pro.  Nirmal Mulaikal is a POLITICO audio host-producer.  Raghu Manavalan is a senior editor for POLITICO audio.
