A 1075 foot elevation is the trigger for a level one shortage.If that shortage is declared, then CAP would lose access to about 320,000 acre-feet or about 20% of what we deliver on annual basis. As Lake Mead continues to fall, if it continues to fall, at 1050 foot, the reduction increases to 400,000 acre-feet to Arizona. At 1025 foot, the reduction would be 480,000 acre-feet to Arizona.
