Big Eddy Marina

Gresham, OR

Big Eddy Marina is located in Gresham, Oregon, along the Sandy River, a tributary of the Columbia River, which ultimately flows into the Pacific Ocean, situating it in the scenic Pacific Northwest region near the foothills of the Cascade Mountains. This marina primarily serves recreational boating on the Sandy River, supporting activities such as freshwater fishing, kayaking, and small boat excursions in a riverine environment. As part of the broader Columbia River basin, it offers access to calmer inland waters rather than open ocean sailing.

Location Gresham, Multnomah County, Oregon
Capacity ~80 slips

Marina Parking & Access Control

Marinas typically need to separate slip holder parking from day-visitor parking, trailer areas, launch ramps, and secure dock access points. Modern facilities use barrier gate systems to enforce these zones automatically — allowing permitted vehicles through via transponder or keycard while logging all access events.
