This hand-tinted photo postcard (courtesy of Theresa and Darrell Eymann) was postmarked Sept. 9, 1908, as “TAHOE, CAL” and mailed to Richmond, Calif. It depicts the source of the Truckee River at Tahoe City.

1908 was five years before the Tahoe City Dam was built to control the top 6 feet of Lake Tahoe’s surface elevation and the flow into the Truckee River.

For comparison, 105 years later, the second photo was taken in April 2013 standing on the dam.

The third photo, also one I took, shows the 100-year-old dam between Fanny Bridge on the Truckee River and the lake outlet.

In the latest telephone scam, callers are now identifying themselves as law enforcement officials.

Real law enforcement is warning citizens to be extra cautious when anyone calls asking for money.

Recently, some local residents have received phones calls from someone claiming to be a Placer County sheriff’s official. They were told there was money owed to them and they were asked to wire money to release the funds. The caller then gives a phone number to call and verify that the caller is indeed a member of law enforcement. The number given should always be verified through other resources and do not take the caller’s word for it.

Detectives advise to never give money or information to anyone you don’t know.

A law enforcement official would never call and ask you to wire money.

If you question the legitimacy of a deputy or detective, call the non-emergency line, (530) 886.5375 to verify if a deputy or detective works at PCSO.
