Ridgefield National Wildlife Refuge Professional Review and Guide
"The Ridgefield National Wildlife Refuge lies just across the Columbia River from the north end of Sauvie Island. Like Sauvie Island, the refuge offers countless paddle trips on its various sloughs, creeks, rivers, and lakes. The geography of the area gives a hint of the possibilities: the refuge is bisected by the Lake River and Bachelor Island Slough, which flow into the Columbia near the mouth of the Lewis River and Gee Creek, while just across the Columbia, Multnomah Channel empties into the Columbia from behind Sauvie Island.
The refuge consists of three parts: the northernmost Carty Unit (where Gee Creek leads to a group of lakes), the southernmost River S Unit, and Bachelor Island. Canoeing is not allowed on the lakes and sloughs of the River S Unit, but boating is allowed on the Lake River, Bachelor Island Slough, and Gee Creek."
