Sgt. Jason Ferguson said on Wednesday that two separate businesses on S. Main Street reported receiving the bills over the course of the two previous days.
He said the department also received information from an Umpqua Bank representative who reported both the Lakeport and Kelseyville branches received four counterfeit $100 bills from different businesses throughout Kelseyville and Lakeport.
The police department encouraged local businesses to become familiar with identifying counterfeit bills.
Police said the Secret Service Web at www.secretservice.gov/money_detect.shtml offers information about identifying counterfeit bills.
Community members with information about the bills or questions can contact the Lakeport Police Department at 707-263-5491.
