Idaho River Flows

The Boise River is also popular for fishing, mostly for rainbow trout and, in the winter, steelhead. Spin-fishermen use roostertail spinners and bait such as worms and Powerbait, while fly fishermen use a variety of flies mimicking the abundant aquatic and terrestrial insects present in the watershed, as well as streamers.

The river is a popular destination for floating, specifically on the Boise greenbelt. Tubers and floaters launch at Barber Park and land at Ann Morrison Park, between major irrigation diversion dams. Several minor diversion weirs are passed as well as several bridges on the 6-mile (10 km) trip. Water skiing is popular above the dam at the Lucky Peak Reservoir.

On the lower (warmwater) course of the river, low summer flows and poorer water quality from agricultural runoff limit fishery production. This section of river supports a fair fishery for largemouth bass, smallmouth bass, and channel catfish. Upstream from Star, the river is a coldwater stream and supports a greater variety of fish. The most prevalent species on this section is mountain whitefish, as well as hatchery-reared rainbow trout, wild rainbow trout, and fingerling brown trout. Upstream from Lucky Peak and Arrowrock reservoirs, the river and its tributaries contain excellent populations of wild rainbow trout, mountain whitefish, and bull trout. This is especially true immediately downstream from the outflow of Anderson Ranch reservoir, where the South Fork takes on the characteristics of a classic “tailwater” for over 5 miles (8 km) from the put-in below the dam to Cow Creek Bridge.

The river was called “Reed’s River” in the early 19th century, named after Pacific Fur Company employee John Reed, who explored parts of the river throughout 1813 and 1814. The river is diverted to canals for irrigation on the plain west of what is now Boise. The dams that form the mountain reservoirs were constructed as part of the Bureau of Reclamation’s “Boise Project” to provide agricultural irrigation, hydroelectricity, drinking water, and flood control to Boise and the Treasure Valley.The Boise River is a 102-mile-long (164 km) tributary of the Snake River in the Northwestern United States. It drains a rugged portion of the Sawtooth Range in southwestern Idaho northeast of Boise, as well as part of the western Snake River Plain. The watershed encompasses approximately 4,100 square miles (11,000 km) of highly diverse habitats, including alpine canyons, forest, rangeland, agricultural lands, and urban areas.

Downstream from its confluence with the South Fork, the river flows generally west, adds the major tributary of Mores Creek along Highway 21, and passes through Lucky Peak Dam to emerge from the foothills southeast of Boise. It passes over several irrigation diversion dams above the city, the first and largest is the century-old Boise River Diversion Dam for the concrete New York Canal, which terminates at Lake Lowell (a.k.a. Deer Flat Reservoir) southwest of Nampa in Canyon County. The next diversion is for the Ridenbaugh Canal (1878) at Eckert Diversion Dam, immediately above Barber Park, five miles (8 km) from downtown Boise. Wooded through the city, the river is lined by an extensive recreational greenbelt. It flows west across the western end of the Snake River Plain in the Treasure Valley and becomes a braided stream with a wide floodplain as it crosses northern Canyon County to the Snake River. At an approximate elevation of 2,100 feet (640 m), it enters the Snake River, the Idaho-Oregon border, west of Parma and three miles (5 km) south of Nyssa, Oregon.Michigan is flanked by four of the five Great Lakes, as well as Lake St. Clair, and boasts the world’s longest freshwater shoreline of any governmental unit.

Hawaii has an abundance of fresh water and hundreds of streams but very few natural lakes. Only In Hawaii, there are just five natural lakes, all of which are quite small, but 266 freshwater reservoirs with a surface area of up to 400 acres have been formed by impounding stream waters.The statistics from both tables calculates the amount of area for each state and the District of Columbia that is covered by perennial water. These calculations don’t include water from intermittent, glacier, and and marsh/swamp sources.The state with the largest total area of water is Alaska, which has 94,743 square miles of water. Alaska contains approximately 12,000 rivers, 3 million lakes larger than 5 acres, and numerous creeks and ponds, accounting for more than 14% of the state’s total area. Hawaii, with 41.2% of its total area water-based, is a close second. Hawaii is the only state that is totally surrounded by water and is made up of islands. Percentage wise, however, Michigan ranks as the number one state with 41.5% of its total area occupied by water. Michigan has more than 64,980 inland lakes and ponds.The recent grip of a multi-year drought in California and the western part of the United States has highlighted just how previous water is as a resource.

The USGS has consolidated a table with the area of each state that covered by water from data provided by the U.S. Census Bureau’s table: Geography: State Area Measurements, 2010.The tile-grid map (see how to make a Tile Grid Map using Excel) below shows which states are the driest (light grey and light blue) and which states are the wettest (medium and dark blues).

The bustling downtown district is littered with unique shops, restaurants, attractions, and galleries. From the Warhawk Air Museum to the Train Depot Museum, there are plenty of things to see and do in Nampa.

This humble vegetable has been a key part of the state’s economy and identity for centuries, and today around one-third of all potatoes grown in the US come from Idaho.The Salmon River, also known as “The River of No Return”, is a river located in the U.S. state of Idaho in the western United States. It flows for 425 miles (685 km) through central Idaho, draining a rugged, thinly populated watershed of 14,000 square miles (36,000 km). The river drops more than 7,000 feet (2,100 m) from its headwaters, near Galena Summit above the Sawtooth Valley in the Sawtooth National Recreation Area, to its confluence with the Snake River. Measured at White Bird, its average discharge is 11,060 cubic feet per second (82,700 US gal/s; 313 m/s). The Salmon River is the longest undammed river in the contiguous United States In the Early to Mid 20th Century other explorers arrived to the Salmon River and ultimately stayed. These early explorers included Frank Lance, Francis, Hank the Hermit, and most well know and storied Buckskin Bill. Sylvan Ambrose Hart (Buckskin Bill) was one of the last Mountain Men to inhabit the Salmon River Canyon at 5 Mile Bar. He arrived to the canyon in/around 1928 from the Oklahoma Territory. For nearly 50 years he lived at 5 Mile Bar and spent less than 50 dollars a year on staples like coffee, tea, chocolate, sugar, flour, etc. Buckskin was a true craftsman in his own right forging his own knives, pistols, rifles, kettles, pots, and pans. Buckskin died in 1980 and his cabin at 5 mile bar has been turned into a museum. The Salmon River originates from and flows through the mountains of central and eastern Idaho (Lemhi Range, Sawtooth, Salmon River Mountains, Clearwater and Bitterroot Range). The main stem rises in the Sawtooth Range at over 9,200 feet (2,800 m) in elevation, several miles northwest of Norton Peak. For the first thirty miles (50 km), it flows north through the Sawtooth Valley, then turns east at Stanley, receiving the Yankee Fork shortly below that point and the East Fork further downstream. The river then flows northeast, receiving the Pahsimeroi River at Ellis and then the Lemhi River at Salmon, Idaho east of the Lemhi Range.

Several national forests and Sawtooth National Recreation Area provide for numerous recreation opportunities within the river’s watershed. Two segments (the Middle Fork and a section of the main Salmon River, known as the Main Fork) are protected as National Wild and Scenic Rivers. The Middle Fork was one of the original eight rivers designated Wild and Scenic in 1968, and is often considered the “crown jewel” of the Wild and Scenic system.

The South Fork of the Salmon flows through Payette National Forest and enters the Wild and Scenic Main Fork at Mackay Bar. The Main Fork raft trip ends about 25 miles (40 km) east of Riggins, either at Vinegar Creek or Carey Creek, marking the beginning of the Lower Salmon rafting section. Boating companies offer both single and multiple day trips on the river.

The Salmon River historically produced 45% percent of all the steelhead (ocean-going rainbow trout) and 45 percent of all the spring and summer chinook salmon in the entire Columbia River Basin. The Salmon River basin contains most (up to 70 percent) of the remaining salmon and steelhead habitat in the Columbia River Basin. Despite abundant, excellent salmon habitat in the Salmon River basin, chinook, steelhead, and sockeye salmon populations have not significantly recovered, despite listings under the federal Endangered Species Act since the mid-1990s. Populations remain at risk in large part because of the negative effects of four federal dams and reservoirs on the lower Snake river, through which both juvenile salmon and returning adults must pass. Many Northwest salmon advocates, commercial & sportfishermen call for removal of the Lower Granite, Little Goose, Lower Monumental, and Ice Harbor dams to address survival problems. As of November 2015, controversy continues in NW Politics, public discourse, and in federal court, where federal salmon recovery plans are under legal challenge. The Middle Fork of the Salmon River is known as one of the best catch and release fly fisheries in the nation. Other recreational activities along the river include camping, hiking and mountain biking. Both the Middle Fork and Main Fork travel through the Frank Church-River of No Return Wilderness Area. The Middle Fork is about 110 miles (180 km) long, while the Main Fork is about 81 miles (130 km) in length. The Middle Fork raft trip run ends 7 miles (11 km) prior to the beginning of the Main Fork run; Corn Creek is the start of the Main Fork section of the Salmon River.The honor didn’t last long; by 1810, maps of the area were already referring to “Louis’ River” as the Salmon. Clark had thought that the Salmon River was the Snake River, thus he called it the “Westerly fork of the Columbia”. The Snake River retained the variant name “Lewis River” or “Lewis Fork” longer than did the Salmon.

In the 1860s, placer deposits of gold were found along the river, and a gold rush began. Miners came to the area, causing clashes with the Nez Perce on their ancestral tribal lands. Many historic and present day mines (including dredging operations) can be seen while traveling along the river.

… I shall in justice to Capt. Lewis who was the first white man ever on this fork of the Columbia Call this Louis’s river. … The Westerly fork of the Columbia River [the present Salmon River] is double the size of the Easterley fork [the present Lemhi River] & below those forks the river is … 100 yards [90 m] wide, it is very rapid & Sholey water Clear but little timber.The river turns abruptly north at the confluence with the Little Salmon River at Riggins, about 87 miles (140 km) above its mouth. From there the river flows almost due north, with U.S. Route 95 crossing the river on the “Time Zone Bridge” just north of Riggins, and then travels on its east bank until a few miles before White Bird. The highway splits north to climb White Bird Hill while the river loops northwest and then south to its confluence with the Snake River north of Hells Canyon, fifteen miles (25 km) south of the Washington border and 40 miles (65 km) upstream of Lewiston. Excluding Alaska, the Salmon River is the longest river system contained entirely within a single U.S. state.

The Salmon is a popular destination for whitewater kayaking, canoeing, and rafting. The canyons of the Salmon allow for magnificent views of the complex geology of the region. The Frank Church-River of No Return Wilderness Area includes one of the deepest canyons in the continental United States, which at roughly 7,000 feet (2,130 m) of vertical relief, is deeper than the Grand Canyon. Outdoor Lodges dot the main canyon of the Salmon River from Salmon, Idaho to Riggins, Idaho. Often the only way to access these lodges is either by motorized boats, rafting trips, hiking, and even some isolated airstrips.

The Salmon River area has been home to people for at least the last 8,000 years. Much of the area was inhabited by several tribes, including the Nez Perce. The river was considered sacred ground and a rich source of food for the indigenous people of the area, who relied on the abundant salmon species and other wildlife.The Snake River covers a distance of 1,078 miles, and it is one of the main tributaries of the Columbia River. The river originates in the western part of Wyoming state and flows through Idaho to Oregon and finally to Washington before emptying into the Columbia River which eventually flows into the Pacific Ocean. The drainage basin of the Snake River covers parts of 6 states in the country. The Native Americans are thought to have lived along the Snake River for more than 11,000 years. The salmon fish from the Pacific Ocean moved in millions upstream of the Snake River to spawn and was, therefore, a source of food for the natives who lived along the river. In the 19th century when the Oregon Trail was well established, it brought settlers and with them the steam boats and railroads that moved different commodities such as minerals and agricultural products along the river for the better part of the 19th century and early part of the 20th century. The watershed of Snake River is the 10th biggest of North America’s rivers and drains an area of about 108,000 square miles and most of its watershed lie between the Rocky Mountains and the Columbia Plateau. The river is the 13th longest rivers in the US.

In 1968 the Congress passed the Wild and Scenic Rivers Act, which was aimed to protect outstanding natural water with cultural and recreational values in their free-flowing condition. The act prohibits development of new dams or any other water project along the riverside lands or the wildlife migration corridors in order to safeguard clean water. The Act also prohibits any other activity that would diminish the unique values of a River.The act protects more than 166 rivers in 38 different states. The state of Idaho has more 1,000 miles long of the country’s most beautiful wild and scenic rivers, which is protected by the Act.Idaho is a state in the northwestern part of the US, and it borders the states of Utah, Nevada, Wyoming, Montana, Oregon, and Washington. On the northern side, the state shares a common border with the province of British Columbia in Canada. The state of Idaho covers an area of about 83,569 square miles and has a population of about 1.7 million people. The state is the 14th largest in the country, the 12th densely populated, and the 7th least populous in the whole country. The state capital of Idaho is the city of Boise, which is also the largest city in the state. Before the European settlement, the region that is now the state of Idaho was inhabited by the Native Americans. At the beginning of the 19th century, it was part of the Oregon County which was hotly contested between Britain and the US. After the signing of the Oregon Treaty in 1846 the territory officially became part of the US, and finally, Idaho joined the union on July 3rd, 1890 and became the 43rd state to join the nation. Some of the largest rivers passing through the state include the Snake River, Bear River, Kootenai River, Salmon River, and Owyhee River among others. Salmon River is Idaho’s longest river that lies wholly within the states.

The river covers a distance of 491 miles, and it is the most significant tributary of the Great Salt Lake. It is also North America’s largest river which does not discharge to the sea. The Shoshone community from antiquity has inhabited the river valley of the Bear River. In 1812, the explorers and the fur traders from the Hudson’s Bay Company started exploring upstream, while the Mormon trail crossed the Bear River in around 1843. The Oregon and California trails followed the river north out of Wyoming to the Fort Hall in the state of Idaho, and some of the explorers on these trails decided to stay on around the river valleys of Utah and Idaho. In the late 1840s, some of the early pioneers of the Mormon trail settled in the Cache Valley. In 1863, the US army troops invaded the Shoshone people in the Cache Valley and killed many of the inhabitants. The episode has been referred to as the Bear River massacre.Listed below are links to the USGS streamflows for our local waters. Don’t forget to check out the helpful links on the left for current streamflow information in your area. The three largest lakes in Idaho are Lake Pend Oreille, Dworshak Reservoir, and Coeur d’Alene Lake. In fact, Lake Pend Oreille is not only the largest lake in Idaho, but it’s also the 38th-largest lake by area in the United States. This map shows the major rivers, reservoirs, and lakes of Idaho. For example, it has the Snake, Salmon, and Boise River. In general, rivers in Idaho flow into the Pacific Ocean and the Great Basin.Snake River is a major river that flows through southern Idaho until forming its western boundary with the state of Oregon. Boise River is another major river in Idaho that flows through Idaho’s capital city of Boise. Idaho’s flow conditions are influenced by its unique hydrology and climate characteristics. The state has numerous major surface flows, including the Snake River, Salmon River, and Clearwater River, all of which are important for irrigation, hydroelectric power, and recreation. Idaho also has several large reservoirs and dams, such as the Boise River Reservoir and Lucky Peak Dam, which play a crucial role in regulating water flow and supply. The state’s watersheds and snowpack levels are also significant indicators of hydrologic conditions, with winter snowpack providing a critical source of water for the state’s rivers and streams during the summer months. Overall, Idaho’s flow conditions are shaped by a complex interplay of natural and human factors, making it an important area of study for hydrologists and water resource managers. Note: Estimates are subject to rapid change due to water availability factors not under PacifiCorp’s control. PacifiCorp provides these estimates as a courtesy for recreational users and makes no guarantee or warranty of their accuracy or fitness for any purpose.These water management data are provisional readings of current river flow conditions. Beware and use caution since river flows can change dramatically because of operational changes at the dams or due to weather conditions.

If you want to spend some time next to the water, spend your day at a riverfront park. Check out our list of nine riverfront parks in Idaho that are absolutely beautiful.A portion of each plate’s registration money will go to funding whitewater access, education and safety programs throughout the state. Another portion will go towards the promotion of Idaho as the Whitewater State. Between 5,000 and 6,000 cfs, the entire Bethine Church River Trail is usually under water, Holloway said. Around 6,000 cfs, paths in Marianne Williams Park start to flood. Parks and Rec has staff checking the Greenbelt multiple times a day to monitor for flooding. According to U.S. Geological Survey data, the average Boise River flow for this time of year is around 2,800 cfs. The river is hovering just under 6,000 cfs, and Roberts said it could fluctuate as high as 6,500 cfs over the weekend. That’s nearly 50,000 gallons of water flowing past a point — the USGS uses the Glenwood Street Bridge as its reference point — in one second.The Boise River has been flowing at around 6,000 cfs for most of the week. Warm weekend temperatures in the mid- to high 80s will likely cause more mountain snow to melt into the reservoirs that supply the river.Since then, two other portions of the path have been closed. Parks and Rec director Doug Holloway told the Statesman people can find closures on the interactive map on the city’s website.

The water table is also starting to show at Ann Morrison Park where the park meets the river, Holloway said. In the past, that hasn’t happened until the river reaches flood stage.

A cold, snowy spring has been a boon for Southwest Idaho’s snowpack and reservoir levels, but as temperatures begin to warm and mountain snow melts, the Boise River is running high.But while the river may not reach flood stage, the high water is still having impacts in Boise. The city’s Parks and Recreation department began closing portions of the Greenbelt more than a week ago, starting with a portion of the Bethine Church River Trail in southeast Boise.

Parts of the Greenbelt are already closed for flooding, and with warm temperatures this weekend and rain in the forecast for next week, flows could increase.

Holloway also urged people to respect the Greenbelt closures and find alternate paths in those areas. On Friday, the Boise Fire Department issued a “Dangerous River Condition” notice warning residents of the potential threats to humans and pets if they enter the frigid, fast-moving water.“It’s a three-part approach where step one is we’re evaluating the snowpack,” Roberts said. “Step two, we’re looking at how much space we have (in the reservoirs) and how much irrigation water we need to provide. And then we’re looking at, how do we stretch that out over time to minimize sudden spikes in the river so that we don’t run out of space in the reservoir.”

The city keeps tabs on which areas of the Greenbelt typically flood at different river flow levels, Holloway said, but he noted that can always change since the river’s natural path changes each year.

Holloway said extensive repairs were made on the banks following widespread flooding in 2017, when the river flows reached as high as 8,600 cfs. Those repairs should help prevent damage to the riverbanks this year, he said. By Thursday, the three reservoirs in the Boise Basin system had room for snowmelt runoff and were at 56% of capacity basin-wide. Arrowrock Reservoir was only 33% full, while Lucky Peak Reservoir was 52% full and Anderson Ranch Reservoir was 75% full. Officials advise the public to be aware of risks associated with increased Boise River flows. The water is deep, cold and fast. Individuals should use extreme caution near the riverbanks.Water managers may continue to adjust water releases from Lucky Peak Dam and Lake during the coming weeks, depending upon weather conditions and inflows. Flows through the City of Boise could also fluctuate depending upon water diversions for irrigation through the New York Canal as determined by Idaho Water District Number 63. The public should exercise increased caution and vigilance around the New York Canal and other water conveyance facilities.

Boise River flows through the City of Boise will increase to a target of approximately 4,000 cubic feet per second by the end of Wednesday, April 12. Flood risk management releases through the city will continue to increase at a daily rate no greater than 500 cfs. The target may increase to 5,000 cfs by Friday, April 14 depending on weather conditions.

Independent sampling is typically at the sampler’s expense. Depending on how many contaminants you test for, a test can range from $15 to hundreds of dollars. Testing for all possible contaminants can reach into the thousands of dollars. If you are interested in independent sampling, identify what contaminants you’d like to test and obtain quotes from multiple labs. DEQ recommends using a laboratory certified to perform drinking water analyses. A list of certified laboratories can be found through the Idaho Bureau of Laboratories directory of labs.Although the water purveyor is responsible through its cross-connection control program to take reasonable measures to protect the water system against contamination and pollution from cross-connections, property owners have a responsibility to install and test backflow prevention assemblies in accordance with their purveyor’s program.

Backflow prevention device – A backflow preventer that does not meet the approval requirements of a backflow prevention assembly (i.e., is not testable):Each year, community water systems in Idaho are required to prepare annual Consumer Confidence Reports for customers. These reports provide consumers with information on where their drinking water comes from and what is in it. Contact your water supplier for information on the latest report. Backpressure – Backflow caused by a downstream pressure that is greater than the upstream or supply pressure in a public water system. Typically caused due to an increase in downstream pressure, a reduction in the potable water supply pressure, or a combination of both. Lead is rarely in drinking water when it leaves the source or treatment plant. Lead is typically introduced to drinking water by leaching into the water from some service lines and plumbing in buildings and homes. This is most prevalent in older structures that still have lead pipes or piping with lead solder. More information on lead in drinking water can be found on EPA’s website.Most homes served by a public water system do not require additional treatment. If you have a private well, spring, or surface water intake, it is your responsibility to test your drinking water to ensure that it is safe. Consumers who choose to purchase a home water treatment unit should research several options to ensure your treatment needs will be met. No single treatment unit will remove every kind of drinking water contaminant. If purchased, follow the manufacturer-recommended operation and maintenance procedures and frequencies to ensure performance. DEQ recommends that any drinking water treatment unit meets American National Standards Institute/National Science Foundation (ANSI/NSF) standards. NSF provides a webpage to narrow your search based on contaminants of interest. Additionally, a PWS may be a consecutive system if it receives some or all of its finished water from one or more wholesale systems. Delivery from a wholesale system to a consecutive connection may be through direct connection or through the distribution system of one or more consecutive systems. For serious issues, notification is required within 24 hours. For less serious issues, notification is required within 3 to 12 months (depending on the violation). Notifications will describe any precautions a consumer needs to take.To help DEQ provide information as quickly as possible, please contact the regional office where the public water system is located. Be prepared with the public water system’s name.
