The Lake Grove Swim Park on Oswego Lake is operated by the Lake Oswego School District (LOSD).

The park property was originally granted via a restrictive deed from the Oregon Iron & Steel Company to the former Lake Grove School District, which merged with the former Oswego School District in 1953 to form LOSD.

Under the terms of the original deed, use of the park is restricted to residents within the boundaries of the former Lake Grove School District, who pay an additional property tax to support the swim park. 

Residents must have a park pass in order to use the swim park. Passes are issued at the swim park and require picture ID with proof of residency (i.e., drivers license). Resident addresses are verified via tax records to determine eligibility.

If you are uncertain if your residence is within swim park boundaries, you may inquire at the park or review your property tax statement. If your property is assessed for the swim park (PARK LK GROVE), you are eligible for a park pass.

All Lake Oswego school children are eligible for swim park swimming lessons, even if their household is not eligible for a park pass.
