Lamb was the sheriff from 1961 to 1979. He'll be honored during a party at Green Valley Ranch on Tuesday when former Nevada Gov. and U.S. Sen. Richard Bryan will make the presentation.
Sheriff Doug Gillespie and former sheriff Bill Young will co-host the event, a benefit for the Injured Police Officers fund.
It's open to the public for a minimum contribution but RSVPs are required at 702-495-3298.
