Luckiamute River
The Luckiamute River is a tributary of the Willamette River, about long, in western Oregon in the United States. It drains an area of Central Oregon Coast Range and the western Willamette Valley northwest of Corvallis. It rises in the remote mountains of southwestern Polk County, about west of Pedee. It flows southeast to Hoskins in Benton County, then northeast into Polk County, past Pedee, then east across southern Polk County. It is joined from the northwest by the Little Luckiamute River. It joins the Willamette from the west about north of Albany. The mouth of the river is about downstream from the mouth of the Santiam River, which enters the Willamette from the east upstream of the Willamette's mouth on the Columbia River. Named tributaries from source to mouth are Boulder, Beaver, Miller, Wolf, Rock Pit, Slick, Cougar, Slide, and Harris creeks. Further downstream are Hull, Foster, Jones, Bonner, Vincent, Plunkett, and Price creeks. Maxfield Creek is next followed by ...

Sarah Helmick State Recreation Site
Sarah Helmick State Recreation Site, also known as Helmick Park, is a state park located south of Monmouth, in Polk County, Oregon, United States. It is located on the floodplain of the Luckiamute River and is forested by Bigleaf Maple, Douglas-fir, and Black Cottonwood trees, among other varieties. The park is named for Sarah Helmick, a pioneer to Oregon in 1845 who donated the original land. Sarah Helmick State Recreation Site is the first state park established in Oregon. It was listed on the National Register of Historic Places in 2022.

Rivers Of Polk County, Oregon
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, an ...

Tributaries Of The Willamette River
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & Scott ...

List Of Longest Streams Of Oregon
Seventy-seven rivers and creeks of at least 50 miles (80 km) in total length are the longest streams of the U.S. state of Oregon. All of these streams originate in the United States except the longest, the Columbia, which begins in the Canadian province of British Columbia and flows 1,249 miles (2,010 km) to the sea near Astoria. The second-longest, the Snake River, which at is the only other stream of more than on the list, begins in Wyoming and flows through parts of Idaho and Washington, as well as Oregon. Some of the other streams also cross borders between Oregon and California, Nevada, Idaho, or Washington, but the majority flow entirely within Oregon. The ''Atlas of Oregon'' ranks 31 rivers in the state by average streamflow; the top five are the Columbia, Snake, Willamette, Santiam, and Umpqua. Not all Oregon rivers with high average flows are on this list of longest streams because neither their main stems nor any of their tributaries (includin ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ash Creek (Polk County, Oregon)
Ash Creek is a short stream in Polk County, in the U.S. state of Oregon.

Main Stem
In hydrology, a mainstem (or trunk) is "the primary downstream segment of a river, as contrasted to its tributaries". Water enters the mainstem from the river's drainage basin, the land area through which the mainstem and its tributaries flow.. A drainage basin may also be referred to as a ''watershed'' or ''catchment''. Hydrological classification systems assign numbers to tributaries and mainstems within a drainage basin. In the Strahler number, a modification of a system devised by Robert E. Horton in 1945, channels with no tributaries are called "first-order" streams. When two first-order streams meet, they are said to form a second-order stream; when two second-order streams meet, they form a third-order stream, and so on. In the Horton system, the entire mainstem of a drainage basin was assigned the highest number in that basin. However, in the Strahler system, adopted in 1957, only that part of the mainstem below the tributary of the next highest rank gets the highest num ...

Ritner Creek
Ritner Creek is a tributary of the Luckiamute River in Polk County in the U.S. state of Oregon.. The map includes mile markers along the Luckiamute River. The creek begins near Bald Mountain in the Central Oregon Coast Range and flows generally southeast to meet the Luckiamute southwest of Pedee and north of Kings Valley. The confluence is upstream of the Luckiamute's mouth on the Willamette River. Named tributaries of Ritner Creek from source to mouth are Sheythe, Love, Clayton, and Kinsey creeks. Ritner Creek passes under Oregon Route 223 just before entering the river. The Ritner Creek Bridge, a covered bridge, carried the highway over the creek until 1976. Replaced by a concrete span, it was the last covered bridge on an Oregon state highway. Name The creek was named for Sebastian Ritner, who emigrated to Oregon in 1845. His donation land claim included part of the creek. A railroad station named ''Ritner'' was part of the Valley and Siletz Railroad. It was along the line a ...

Columbia River
The Columbia River (Upper Chinook: ' or '; Sahaptin: ''Nch’i-Wàna'' or ''Nchi wana''; Sinixt dialect'' '') is the largest river in the Pacific Northwest region of North America. The river rises in the Rocky Mountains of British Columbia, Canada. It flows northwest and then south into the U.S. state of Washington, then turns west to form most of the border between Washington and the state of Oregon before emptying into the Pacific Ocean. The river is long, and its largest tributary is the Snake River. Its drainage basin is roughly the size of France and extends into seven US states and a Canadian province. The fourth-largest river in the United States by volume, the Columbia has the greatest flow of any North American river entering the Pacific. The Columbia has the 36th greatest discharge of any river in the world. The Columbia and its tributaries have been central to the region's culture and economy for thousands of years. They have been used for transportation since a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Santiam River
The Santiam River is a tributary of the Willamette River, about long, in western Oregon in the United States. Through its two principal tributaries, the North Santiam and the South Santiam rivers, it drains a large area of the Cascade Range at the eastern side of the Willamette Valley east of Salem and Corvallis. Watershed The main course of the river is short, formed in the Willamette Valley by the confluence of the North and South Santiam rivers on the border between Linn and Marion counties approximately northeast of Albany. It flows generally west-northwest in a slow meandering course to join the Willamette from the east approximately north of Albany. Both the North and South Santiam rise in high Cascades in eastern Linn County. The Middle Santiam River joins the South Santiam where the South Santiam is impounded to form Foster Lake. The North Santiam is impounded to form the deep Detroit Lake in the Cascades. The Santiam is a major source of water supply for Salem. ...
