How ReportLost works in Lake Oswego
You describe what you lost
Tell us what went missing, where, and when. We gather the details needed to notify the right places without you having to contact each one separately.
We route it to the right channels
We notify the Lake Oswego Police Department Property and Evidence Unit, TriMet (if transit is involved), local found item networks, and community groups. No need to chase down phone numbers or offices.
Your report searches continuously
For the full duration of your plan, your report stays active and matches against incoming found items, marketplace posts, and community alerts. You don't refresh Facebook or Nextdoor yourself, we alert you when there's a credible match.
Where to report a lost item in Lake Oswego
Below are the main places to file a report. ReportLost handles the routing for you, but here's what each office covers.

TriMet Transit Lost and Found
If you lost something on a TriMet bus in Lake Oswego, TriMet's Lost and Found office processes claims. We generate the exact details to report, so you don't have to repeat your story.
Lake Oswego City Hall
City services and municipal offices can direct you to lost items found in public areas, parks, or city facilities. We connect your report with the right department when needed.
Lost Pet
If you've lost a pet, report it right away. Oregon Humane Society and local animal services track found animals, and community networks like the Lost/Found Pets Lake Oswego group share alerts. For priority handling, file a priority lost pet report with us.

Your report starts working immediately
The sooner you file, the better your chances. Once submitted, your report is active and searching, and our team begins routing to the right places. You can take a breath, knowing you've done the most important step.
Report my lost item →Losing something in Lake Oswego means navigating separate systems, each with its own phone number, office hours, and procedures. The Police Department's Property and Evidence Unit handles some items, TriMet covers transit losses, and community groups like the Lake Oswego Neighborhood pages manage other finds. Coordinating across all of them while racing against storage deadlines is exhausting.
ReportLost simplifies this. One form, one team behind the scenes, and a report that keeps working for you. Once you submit, we connect you with the right channels and your report continues searching for a match for months, so you can focus on other things while your lost item gets found.
