Collins Beach is a sandy beach on the Columbia River side of Sauvie Island in Oregon, United States, located north of Portland. Part of it is a clothing-optional area. The beach is one mile (1.6 km) long and begins about 0.25 miles (400 m) after Reeder Road becomes gravel. Hours are 4:00 a.m. to 10:00 p.m. every day. The beach has been popular for nude use since at least the 1970s. It is surrounded by a 12,000-acre (49 km2) fish and game reserve, except for a 10-acre (4.0 ha) parcel of privately owned land west of Reeder Road at the north boundary of Collins Beach. Nude beach users continue onto the non-nude North Unit Beach which is poorly delineated and ineffectively screened from view, which has led to a legal complaint by the property owners.Collins Beach is one of two official clothing-optional beaches in Oregon after Glass Bar Island's in Eugene, Oregon closed. The other is Rooster Rock State Park. It is administered by the Oregon Department of Fish and Wildlife in cooperation with the Columbia County Sheriff's Office.

Bachelor Island is an island in the U.S. state of Washington. It is located in the Columbia River near Ridgefield, just south of the mouth of the Lewis River and a few miles north of the mouth of the Willamette River. The island stretches from Columbia river mile 88 to 91.5 (142 to 147 km). The northern end of Sauvie Island lies across the Columbia from Bachelor Island.Bachelor Island is separated from the mainland by Bachelor Island Slough and Lake River. Bachelor Island Slough separates from the Columbia River at Bachelor Point and the southern end of Bachelor Island. The slough joins Lake River, which empties into the Columbia River at the northern end of Bachelor Island.Most of Bachelor Island is part of the Ridgefield National Wildlife Refuge.

Scappoose Bay is a slough of Multnomah Channel, a distributary of the Willamette River, about 1 mile (1.6 km) upstream of where the channel meets the Columbia River in Columbia County, Oregon, United States. It is surrounded by a broad wetland area full of small ponds and other waterways across from Sauvie Island. It lies between Scappoose to the south and St. Helens to the north. A few small streams, including Milton Creek and Scappoose Creek drain from the east slopes of the Oregon Coast Range into the bay. Lying in the upper portion of the Columbia River Estuary, Scappoose Bay is tidal but is a freshwater body.The original inhabitants of the Scappoose Bay area were the Chinookan peoples who hunted, fished, and gathered in the area. During the 19th century, American settlers developed the area, clearing land for farming. Wood product manufacturing began in the early 20th Century. Three now-defunct factories left behind hazardous materials.Scappoose Bay is an important home for several fish species. Sturgeon poaching has become a problem there in recent years. An advisory from the Oregon Department of Environmental Quality against consuming fish and shellfish from the bay remains in effect due to contamination from former industrial activity.

Milton Creek, is a waterway in Columbia County, Oregon, United States. It is 28.5 miles (45.9 km) long, rising in the Oregon Coast Range and emptying into Scappoose Bay – a slough of Multnomah Channel – one of the distributaries of the Willamette River where it enters the Columbia River. The creek was named for a small settlement that was founded at the mouth of the creek in 1846, but later became Houlton because there was already a post office in Oregon with the name Milton (Milton-Freewater). Houlton was later absorbed into St. Helens.The creek is home to several fish species, including steelhead trout, cutthroat trout, and coho salmon. Much of the undeveloped portion of the watershed is heavily forested. The upper reaches of Milton Creek receive around 60 inches (1,500 mm) of precipitation a year, while the lower elevations closer to the Columbia River see closer to 50 inches (1,300 mm).Portions of Milton Creek have been significantly altered since permanent settlement came to the region for both farming and transporting logs. The lower 2 miles (3.2 km) originally flowed into the Columbia River through Jackass Canyon to the north of the courthouse in St. Helens but was relocated to its present path in 1861. Scappoose Bay and Multnomah Channel was later lined with levees to protect from flooding. The Scappoose Bay Watershed Council has undertaken several restoration projects along the creek and other Scappoose Bay tributaries since 2001.

Lake River is a tributary, about 11 miles (18 km) long, of the Columbia River in the U.S. state of Washington. It flows north from Vancouver Lake in Vancouver to meet the larger river near Ridgefield and the northern tip of Bachelor Island. The Wilkes Expedition of 1841 referred to Lake River as Calipaya Inlet.The river is part of the 32-mile (51 km) Lewis River – Vancouver Lake Water Trail linking Vancouver Lake to Woodland by waters suitable for kayaks and other boats. Portions of the Ridgefield National Wildlife Refuge border the river.
