Tideman Johnson Natural Area is a city park of about 7.7 acres (3.1 ha) in southeast Portland, in the U.S. state of Oregon. Located at Southeast 37th Avenue and Tenino Street along Johnson Creek, the site is named for a mid-19th century family named Johnson that encouraged public use of its land along the creek. The park has paved and unpaved paths for hiking. A loop trail and boardwalk off the Springwater Corridor runs through the park.
A good area for bird-watching, the park attracts owls, pigeons, kingfishers, and herons.In late spring and early summer, Tideman Johnson's big-leaf maples, alders, and other trees are frequented by warblers, grosbeaks and mourning doves. Other birds commonly seen in the park include sapsuckers, woodpeckers, chickadees, and bushtits. During a restoration project completed in 2006, workers identified 22 fish species in the creek at Tideman Johnson and counted 23 Chinook salmon and 107 steelhead trout.
Portland's Bureau of Environmental Services (BES) undertook the 2006 project to repair a sewer line that runs through the park. In 1922, when it was constructed, the Lents Interceptor sewer was buried about 5 feet (1.5 m) beneath Johnson Creek. Over the years, the stream washed away the fill above the pipe, exposing it to possible damage. Workers surrounded the pipe with concrete during the project and covered it with rock. They also reshaped stream banks, planted 5,300 trees and shrubs, and added boulders and woody debris to the stream to prevent erosion and improve fish habitat.

The Necanicum River is a river on the Pacific coast of northwest Oregon in the United States, approximately 21 miles (34 km) long. It drains a timber-producing area of the Northern Oregon Coast Range northwest of Portland. It forms the first estuary south of the mouth of the Columbia River along the Oregon Coast, reaching the Pacific Ocean at Seaside in Clatsop County.
Forest Park is a public municipal park in the Tualatin Mountains west of downtown Portland, Oregon, United States. Stretching for more than 8 miles (13 km) on hillsides overlooking the Willamette River, it is one of the country's largest urban forest reserves. The park, a major component of a regional system of parks and trails, covers more than 5,100 acres (2,064 ha) of mostly second-growth forest with a few patches of old growth. About 70 miles (110 km) of recreational trails, including the Wildwood Trail segment of the city's 40-Mile Loop system, crisscross the park.
Rock Creek is a free-flowing tributary of the Potomac River that empties into the Atlantic Ocean via the Chesapeake Bay. The 32.6-mile (52.5 km) creek drains about 76.5 square miles (198 km2). Its final quarter-mile is affected by tides.
The Bull Run River is a 21.9-mile (35.2 km) tributary of the Sandy River in the U.S. state of Oregon. Beginning at the lower end of Bull Run Lake in the Cascade Range, it flows generally west through the Bull Run Watershed Management Unit (BRWMU), a restricted area meant to protect the river and its tributaries from contamination. The river, impounded by two artificial storage reservoirs as well as the lake, is the primary source of drinking water for the city of Portland, Oregon.
Putah Creek is a major stream in Northern California, a tributary of the Yolo Bypass, and ultimately, the Sacramento River. The 85-mile-long (137 km) creek has its headwaters in the Mayacamas Mountains, a part of the Coast Range, and flows east through two dams. First, Monticello Dam forms Lake Berryessa, below which Putah Creek forms the border of Yolo and Solano Counties, and then flows to the Putah Diversion Dam and Lake Solano. After several drought years in the late 1980s, the majority of Putah Creek went dry, prompting a landmark lawsuit that resulted in the signing of the Putah Creek Accord in 2000. The Accord established releases from the dams to maintain stream flows in Putah Creek, with natural flow regimes which spike in winter/spring and ebb in summer/fall. The restoration of natural flow regimes has resulted in a doubling of riparian bird species and a return of spawning native steelhead trout and Chinook salmon, as well as protecting the livelihood of farmers on the lower watershed.
Daylighting can be defined as "“opening up buried watercourses and restoring them to more natural conditions". An alternative definition refers to "“the practice of removing streams from buried conditions and exposing them to the Earth's surface in order to directly or indirectly enhance the ecological, economic and/or socio-cultural well-being of a region and its inhabitants”. The term is used to refer to the restoration of an originally open-air watercourse, which had at some point been diverted below ground, back into an above-ground channel. Typically, the rationale behind returning the riparian environment of a stream, wash, or river to a more natural state is to reduce runoff, create habitat for species in need of it, or improve an area's aesthetics. In the UK, the practice is also known as deculverting.
Ardenwald-Johnson Creek is a neighborhood straddling the border between Portland and Milwaukie, Oregon. It is recognized by both Portland's Office of Neighborhood Involvement as well as Milwaukie's Neighborhoods Program.
Pilarcitos Creek is a 13.5-mile-long (21.7 km) coastal stream in San Mateo County, California, United States, that rises on the western slopes of the Santa Cruz Mountains and descends through Pilarcitos Canyon to discharge into the Pacific Ocean Half Moon Bay State Beach.
Johnson Creek is a 25-mile (40 km) tributary of the Willamette River in the Portland metropolitan area of the U.S. state of Oregon. Part of the drainage basin of the Columbia River, its catchment consists of 54 square miles (140 km2) of mostly urban land occupied by about 180,000 people as of 2012. Passing through the cities of Gresham, Portland, and Milwaukie, the creek flows generally west from the foothills of the Cascade Range through sediments deposited by glacial floods on a substrate of basalt. Though polluted, it is free-flowing along its main stem and provides habitat for salmon and other migrating fish.
Tryon Creek is a 4.85-mile (7.81 km) tributary of the Willamette River in the U.S. state of Oregon. Part of the drainage basin of the Columbia River, its watershed covers about 6.5 square miles (16.8 km2) in Multnomah and Clackamas counties. The stream flows southeast from the Tualatin Mountains through the Multnomah Village neighborhood of Portland and the Tryon Creek State Natural Area to the Willamette in the city of Lake Oswego. Parks and open spaces cover about 21 percent of the watershed, while single-family homes dominate most of the remainder. The largest of the parks is the state natural area, which straddles the border between the two cities and counties.
The Springwater Corridor Trail is a bicycle and pedestrian rail trail in the Portland metropolitan area in Oregon, United States. It follows a former railway line from Boring through Gresham to Portland, where it ends south of the Eastbank Esplanade. Most of the corridor, about 21 miles (34 km) long, consists of paved, off-street trail, though about 1 mile (1.6 km) overlaps city streets in Portland's Sellwood neighborhood. A large segment roughly follows the course of Johnson Creek and crosses it on bridges many times. Much of the corridor was acquired by the City of Portland in 1990; remaining segments were acquired by Metro thereafter.
Fanno Creek is a 15-mile (24 km) tributary of the Tualatin River in the U.S. state of Oregon. Part of the drainage basin of the Columbia River, its watershed covers about 32 square miles (83 km2) in Multnomah, Washington, and Clackamas counties, including about 7 square miles (18 km2) within the Portland city limits.
Balch Creek is a 3.5-mile (5.6 km) tributary of the Willamette River in the U.S. state of Oregon. Beginning at the crest of the Tualatin Mountains, the creek flows generally east down a canyon along Northwest Cornell Road in unincorporated Multnomah County and through the Macleay Park section of Forest Park, a large municipal park in Portland. At the lower end of the park, the stream enters a pipe and remains underground until reaching the river. Danford Balch, after whom the creek is named, settled a land claim along the creek in the mid-19th century. After murdering his son-in-law, he became the first person legally hanged in Oregon.
The Columbia Slough is a narrow waterway, about 19 miles (31 km) long, in the floodplain of the Columbia River in the U.S. state of Oregon. From its source in the Portland suburb of Fairview, the Columbia Slough meanders west through Gresham and Portland to the Willamette River, about 1 mile (1.6 km) from the Willamette's confluence with the Columbia. It is a remnant of the historic wetlands between the mouths of the Sandy River to the east and the Willamette River to the west. Levees surround much of the main slough as well as many side sloughs, detached sloughs, and nearby lakes. Drainage district employees control water flows with pumps and floodgates. Tidal fluctuations cause reverse flow on the lower slough.
Crystal Springs Creek, a 2.7-mile (4.3 km) tributary of Johnson Creek, flows entirely within the city of Portland in the U.S. state of Oregon. The stream rises from springs near the Reed College campus in the southeastern part of the city and runs generally southwest to meet Johnson Creek in the Portland neighborhood of Sellwood.
Boeing Creek is a stream in the U.S. state of Washington, located in the city of Shoreline, just north of Seattle. It is about 1.6 miles (2.6 km) long and empties into Puget Sound. The creek is heavily modified along its course, and in many places has been diverted into culverts. The watershed of Boeing Creek is about 11.2 square miles (29 km2) in size, with two main tributaries aside from the mainstem. The creek takes its name from William Boeing, who built a mansion along the creek in 1913. Despite the river modifications and stormwater pollution, the creek supports a variety of riparian habitats, native animals and fishes.
The Trout Creek Mountains are a remote, semi-arid Great Basin mountain range mostly in southeastern Oregon and partially in northern Nevada in the United States. The range's highest point is Orevada View Benchmark, 8,506 feet (2,593 m) above sea level, in Nevada. Disaster Peak, elevation 7,781 feet (2,372 m), is another prominent summit in the Nevada portion of the mountains.
Little Butte Creek is a 17-mile-long (27 km) tributary of the Rogue River in the U.S. state of Oregon. Its drainage basin consists of approximately 354 square miles (917 km2) of Jackson County and another 19 square miles (49 km2) of Klamath County. Its two forks, the North Fork and the South Fork, both begin high in the Cascade Range near Mount McLoughlin and Brown Mountain. They both flow generally west until they meet near Lake Creek. The main stem continues west, flowing through the communities of Brownsboro, Eagle Point, and White City, before finally emptying into the Rogue River about 3 miles (5 km) southwest of Eagle Point.
Stephens Creek, a 2-mile (3 km) tributary of the Willamette River, flows entirely within the city of Portland in the U.S. state of Oregon. Beginning in the neighborhood of Hillsdale, it runs generally east through residential and commercial neighborhoods as well as patches of forest and parkland to join the Willamette slightly north of the Sellwood Bridge. Its course passes under Interstate 5 and down the canyon followed by Southwest Taylors Ferry Road. Stephens Creek enters the river at Willamette Moorage Park, which is part of a 35-acre (14 ha) group of natural areas called the South Portland Riverbank. The natural areas include Butterfly Park and Willamette Park as well as the moorage park and other public land parcels.
Oaks Bottom Wildlife Refuge is a city park of about 141 acres (57 ha) in southeast Portland, in the U.S. state of Oregon. Located in a floodplain along the east bank of the Willamette River near Sellwood, the park is known for attracting a wide variety of birds. In 1988, the park was named Portland's first wildlife refuge, and in 2004, it was designated the city's first migratory bird park.
