Downie River
The Downie River is an approximately tributary of the North Yuba River in Sierra County, California, in the United States.
The river originates from the confluence of the West Branch Downie River and Rattlesnake Creek in the Tahoe National Forest, and flows south to its confluence with the North Yuba at Downieville.
The river drains a mountainous watershed of about in the northern Sierra Nevada.
Tributaries include Lavezzola Creek and Pauley Creek, which both join the Downie from the left shortly above the mouth.
The river and town are named after Scottish prospector William Downie, who settled here in 1850.
Don River (North Queensland)
The Don River is a river located in North Queensland, Australia.
East Fork Coquille River
The East Fork Coquille River is a tributary, about long, of the North Fork Coquille River in the U.S. state of Oregon.
It begins near Bennett Rock in Douglas County in the Southern Oregon Coast Range.
The East Fork flows generally west through the Brewster Valley near the rural community of Sitkum to the vicinity of Dora in Coos County.
Downstream of Dora, the river turns southwest to meet the North Fork at Gravelford.
The mouth of the East Fork is about from the North Fork's confluence with the South Fork Coquille River near Myrtle Point and river miles from the Coquille River mouth on the Pacific Ocean at Bandon.
The land in the watershed is used mainly for timber production and farming; commercial forests dominate in much of the region.
Stuart River (Minnesota)
The Stuart River is a river located in Minnesota, in the United States.
Coquille River (Oregon)
The Coquille River is a stream, about long, in southwestern Oregon in the United States.
It drains a mountainous area of of the Southern Oregon Coast Range into the Pacific Ocean.
Its watershed is between that of the Coos River to the north and the Rogue River to the south.
Yuba River
The Yuba River is a tributary of the Feather River in the Sierra Nevada and eastern Sacramento Valley, in the U.S. state of California.
The main stem of the river is about long, and its headwaters are split into three major forks.
The Yuba River proper is formed at the confluence of the North Yuba and Middle Yuba Rivers, with the South Yuba joining a short distance downstream.
Measured to the head of the North Yuba River, the Yuba River is just over long.
The river drains, mostly in the western slope and foothills of the Sierra Nevada.
The average runoff of the Yuba River basin is approximately per year, providing about one- third of the flow of the Feather River, and 10 percent of the flow of the Sacramento River, which the Feather ultimately drains into.
Since the early 20th century, the river's flow has been gradually reduced by irrigation and hydropower diversion projects.
The river's name comes from a Maidu village, spelled in early records as Yubu and applied to the river by 1844.
Some claim the name is a variant of Spanish" uba" or" uva", referring to grapes found growing along the banks of the river.
South Fork Coquille River
The South Fork Coquille River is the longest tributary of the Coquille River in coastal Oregon in the United States.
From its headwaters in the Southern Oregon Coast Range, the river flows northwest to join the North Fork Coquille River at Myrtle Point, forming the main stem Coquille.
The South Fork is about long, and its watershed drains roughly of rural Coos County.
North Fork Coquille River
The North Fork Coquille River is a tributary of the Coquille River in the southern Oregon Coast Range in the U.S. state of Oregon.
It begins at an elevation of about above sea level and drops to near Myrtle Point, where it joins the South Fork Coquille River to form the main stem.
North Yuba River
The North Yuba River( also called the North Fork Yuba River) is the main tributary of the Yuba River in northern California in the United States.
The river is about long and drains from the Sierra Nevada westwards towards the foothills between the mountains and the Sacramento Valley.
It rises on the Sierra Crest about northwest of Sierraville.
The river flows west through meadows, then south into a gorge, turning west again, followed by California State Route 49.
The river's four major tributaries, the Downie River, Goodyears Creek, Canyon Creek and Slate Creek, enter from the right before the river abruptly turns south at the New Bullards Bar Reservoir, formed by the New Bullards Bar Dam.
The dam is situated right above the river's mouth; just after the North Yuba leaves the dam it empties into the Middle Yuba River and forms the Yuba River.
Middle Yuba River
The Middle Yuba River is one of the three main forks of the Yuba River in Northern California in the United States.
The river rises at the crest of the Sierra Nevada, and flows generally west through canyons to join the North Yuba River near North San Juan.
The confluence of the two rivers forms the main stem of the Yuba River, which then continues west to join the Feather River.
The Middle Yuba forms much of the border between Nevada County and Sierra County and in its lower reaches a small segment of the Nevada–Yuba County line.
The Middle Yuba drains a remote, rugged portion of the Tahoe National Forest, with elevations ranging from at English Mountain to at the confluence with the Yuba River.
The river is dammed and diverted several times to provide hydroelectricity, greatly reducing the flow in all but the wettest years.
Jackson Meadows Dam and Milton Diversion Dam near the headwaters are part of the Yuba-Bear Hydroelectric Project, which transport water to the South Yuba and Bear Rivers.
Jackson Meadows Reservoir, stocked with 10,000 pounds of rainbow trout annually, is also a popular recreation area.
Further downstream, Our House Dam diverts water through a series of tunnels to New Bullards Bar Reservoir on the North Yuba River.
Water is also taken from Oregon Creek, the main tributary of the Middle Yuba.
This enables the generation of more power at the New Colgate Powerhouse, situated downstream from the confluence of the North and Middle Yuba Rivers.
The Middle Yuba River was a major mining site during the California Gold Rush.
It was one of the areas most heavily affected by hydraulic mining, which washed large volumes of loose sediment into the river channel.
In 1941 the Englebright Dam was constructed on the Yuba River below the Middle Fork to capture this debris before it could travel further downstream.
In 2008 studies were carried out by the Nevada Irrigation District, which owns Jackson Meadows and Milton Dams, to determine optimum flows for whitewater boating.
This may ultimately result in the restoration of some of the natural flows to the Middle Yuba.
The minimum required release from Milton Dam is , a tiny fraction of the pre-development flow.

Question: Are both Coquille River (Oregon) and North Yuba River located in the same country?
Answer: yes
