Easement Members

Easements provide access to property owners in the City of Lake Oswego who have special deeded lake access privileges. Eligibility for lake access privileges to use Oswego Lake are determined by references to historical documents, including the express granting of lake access privileges by Oregon Iron and Steel Company in recorded, real property instruments. Lake access privileges cannot be sold, purchased or transferred.

LOC owns 20 lakeside properties at various locations around the lake to allow eligible easement members to exercise lake access privileges. There are over 3,000 homes in Lake Oswego whose residents are eligible to exercise lake access privileges. Each easement is governed by its own individual set of by-laws and has its own volunteer board of directors. Facilities and rate structures vary from easement to easement.

Yes. If you are a current, paid, easement member you can moor a boat at LO Landing, located in the two story office building next to the LOC marina. They may also have a waiting list, but typically their slips turn over more rapidly than those at the easements. You can reach them at 503-545-8870 or

You also have the option to “day use.” Limitations are:

  • You must pull your boat from the lake prior to the LOC Marina’s closing time (7 pm nightly during the summer).
  • The LOC does not have parking for your truck or trailer on the premises.
  • Boats entering the lake must either have an intact and unaltered wire clip or be decontaminated prior to launch.

Contact information for easement officers is located on each easements webpage. Learn more about how to join an easement as well as a list of all easements here. Contact the easement(s) you are eligible to join and decide which easement you want to join. Fill out their application and pay their dues. In addition, you need to register with the LOC. You will need to fill out the Registration for Lake User and email to You will then receive an email to pay your fees online.

Enter your address into the Easement Eligibility Lookup Tool. You may also refer to our Easement Map for a general idea. However, to confirm access you must call the LOC office at 503-636-1422. We have a database of properties with deeded rights. You will need to have the property address to determine access eligibility.


The marina dispenses Non-Ethanol Regular (87) and Premium (92) fuel. As a general rule, most boats run on Regular.
The marina is the heart of the lake operations. There is a small convenience store that offers snacks, a limited variety of boat safety gear and the only place to fuel your boat on the lake. The marina is also where you license your watercraft, take your written boating exam and launch your boat.

Licensing & Registration

The wire tie is our way of monitoring boats and trailers coming in and out of the lake to determine whether they need to be steam cleaned. If the wire tie is intact and unaltered, it indicates that the boat has not left the trailer and so has not been launched in another body of water and does not require steam cleaning to launch.

There are a number of invasive plants in other bodies of water, such as the Willamette and Columbia Rivers, that are not currently in the lake. Milfoil is an example of one that grows rapidly and costs a great deal of money to keep from spreading. Requiring boats and trailers to be steam cleaned prior to launch is our best defense in keeping new invasive plant problems out of our lake.

There are three LOC-approved vendors that can clean your boat and attach the required LOC tag:
West One Marine 221 Foothills Road, Lake Oswego 503-702-0450
River City Boat Sales & Marine Services 26177 Boones Ferry Landing, Aurora 503-797-2222
NW Boat Sports 18649 S Hwy 99 E, Oregon City 503-305-5168

You may schedule an appointment to launch your boat when the following items are complete:

  • All assessments, late fees & attorney fees, if any, must be current.
  • A current boat insurance declaration page must be on file.
  • A copy of your boat title or temporary title must be on file.
  • A completed Wake Enhancement Device Certification & Agreement must be on file.
  • All required State and/or LOC licensing must be current and properly displayed.
  • Must have a licensed operator listed on record.

Operator Licenses are for powerboats only and are not required for non-power vessels.

Powerboat operators must be licensed to operate a powerboat on Oswego Lake.

Operator’s licenses are valid for a lifetime as is the Oregon State Marine Board Boater Education Card. However, if you have been off the lake for more than two years you will need to retake the written exam.

To receive an operator license you must have an Oregon State Marine Board Boater Education Card, take and pass the LOC written exam and complete the LOC driving exam within 60 days.


Everyone, regardless of age, must carry an Oregon State Marine Board (OSMB) Boater Education Card. View full details about this card and how to study for this exam on the OSMB website. Boater education material can also be picked up in the marina.

You can take the Oregon State Marine Board Boater Education course offered by the Boat U.S. Foundation.

The BoatUS Foundation’s Online Boating Safety Course is the only free course approved by the Oregon State Marine Board. Once you pass the course, you may print your certificate to use for the next 30 days. Next, purchase your Boater Education Card for $20 through the Oregon State Marine Board website or through the BoatUS site for $21. This is a one-time fee and the card is good for life.

You must bring a copy of your certificate of completion or your Boater Education Card with you to the LOC marina when you take your LOC written exam. The exam covers the Lake Oswego Corporation Rules & Regulations of Oswego Lake. You do not need an appointment to take the written exam during regular marina hours.

Upon completion of the LOC written exam you have 60 days to take the driving portion of the exam to receive your Standard Operator’s License. Driving exams are by appointment only.


Wake Enhancing Devices are NOT allowed on the lake.

Some manufacturers offer devices to make boat wakes larger. A larger boat wake can make the lake very choppy and potentially unsafe or unusable for some users (canoes, water skiers, etc). Additionally, property damage can occur to shoreline structures resulting in degraded water quality. To help in managing wakes, boats with wake enhancement devices will not be allowed to operate on the lake.

The LOC requires disabling procedures to be performed on boats with wake enhancement devices before they can be operated on the lake. If you have a wake enhancement device on your boat, you must complete the Wake Enhancement Device Certification and Agreement form.

Form must be completed and signed by a boat mechanic and also signed by the boat owner.

Owners of boats retrofitted with water bladders such as “Fat Sacks” must have the water bladders removed. Passive wake enhancement is also not allowed. The most common passive devices are sand bags or free weights. Lead plating is another form of passive device.

You can use any boat mechanic to make the changes as long as the technician signs the LOC Wake Enhancement Device Certification and Agreement confirming the changes were made following our guidelines. All work performed on the boat must be listed on the Agreement. You cannot certify your own boat.

If you are caught using water bladders, passive wake enhancing devices, or any other wake enhancing devices, your boat will be subject to removal from the Lake for twelve months with no exceptions.


Manufacturers are designing boats smaller than 22.0 feet to produce massive wakes. No boat designed to produce these large wakes will be licensed on the lake. The hull design characteristics and description published by the boat manufacturer to market the boat will determine whether a boat qualifies for use on the lake. Please check with LOC staff before purchasing your boat to ensure it is eligible to be licensed for use on the lake.

Pop-Up Concerts

Pop-Up Fridays are live concerts on Oswego Lake featuring local bands and occur on several Fridays throughout the summer. Check our event calendar for this year’s concerts.

This relatively new event was created during the COVID-19 global pandemic as a way to safely hold entertainment on the lake. The 90-minute event runs from 6:00 pm – 7:30 pm with no breaks. The location changes each week and is revealed by email 30 minutes before the concert.

We release the location for Pop-Up Friday nearer to the event start time to enrich the unique experience and sustain the spirit of our event. By doing so, we’ve noticed that it minimizes congestion and promotes a more relaxed day on the lake. This gives everyone an opportunity to enjoy their time without rushing to secure a spot for the evening’s entertainment. The late disclosure of the location ensures a smoother transition to the pop-up event, thereby contributing to an enjoyable and harmonious Friday gathering for our community.

If you have a recommendation for next year, please email it to You can also email any feedback – especially praise! – to that same email address, which will go directly to the Events Committee of the Board of Directors.

  • Tie ups begin at 6:00 pm – NO SOONER
  • All boats should have anchor with a minimum of 25 feet of line
  • First come, first served parking
  • Boat captains are responsible for the behavior and safety of EVERY person who arrives at the event in your boat
  • Boaters who enter event in disorderly fashion or otherwise disregard Lake Patrol instructions will be asked to leave
  • Concert area is NO WAKE ZONE beginning at noon on day of event

At the first pop-up event, several boats graciously drove to the barge afterward to tip the band. For convenience, we started asking bands for their Venmo information to provide an easier way for people who want to tip to do so. Tipping is not expected, but is very much appreciated!

These vibrant concerts, featuring a diverse array of musicians and artists, are provided by the generous sponsorship of Harnish Properties.
