Lake Grove Swim Park

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

The park may be used by all LOSD students. Students under 7 years of age must be accompanied by a guardian who has access to the park.

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. Lake Grove Swim Park Deed

In addition to all LOSD students, under the terms of the original deed, non-LOSD students' use of the park is restricted to those who reside within the boundaries of the former Lake Grove School District. (See Swim Park Boundary Map)

Residents must have a park pass issued annually in order to use the swim park. Passes are issued annually 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 children are eligible for swim park swimming lessons, even if their household is not eligible for a park pass.
