The Humboldt River is an extensive river drainage system located in north-central Nevada. It extends in a general east-to-west direction from its headwaters in the Jarbidge, Independence, and Ruby Mountains in Elko County, to its terminus in the Humboldt Sink, approximately 225 direct miles away in northwest Churchill County.[4] Most estimates put the Humboldt River at 300 to 330 miles (480 to 530 km) long[5][6] however, due to the extensive meandering nature of the river, its length may be more closely estimated at 380 miles (610 km).[7] It is located within the Great Basin Watershed and is the third longest river in the watershed behind the Bear River at 355 miles (571 km) and the Sevier River at 325 miles (523 km). The Humboldt River Basin is the largest sub-basin of the Great Basin encompassing an area of 16,840 square miles (43,600 km2).[4] It is the only major river system wholly contained within the state of Nevada.

It is the only natural transportation artery across the Great Basin and has historically provided a route for westward migration. Additionally, two major railroad routes loosely follow its path. Interstate 80 follows the river's course from its source to its mouth. The river is named for the German naturalist Alexander von Humboldt.[8][9]

History

The region of the river in northern Nevada was sparsely inhabited by

European American settlers.[10] The region was little known by non-indigenous peoples until the arrival of fur trappers
in the early 19th century.

The first recorded sighting of the river was on November 9, 1828, by

draft animals

In 1841 the river (then known as Mary's River) first became the route of the

Transcontinental Railroad.[3]

In the 20th century, the valley of the river became the route for

Interstate 80.[14] In the latter part of the 20th century, about 45,000 people lived within 10 miles (16 km) of the river, roughly a third of the population at that time of the State of Nevada outside of Western Nevada and Southern Nevada
, before the rapid 21st-century growth of Southern Nevada changed these population figures.

Watershed and course

The Humboldt River can be divided geographically into the upper, middle, and lower divisions based on Palisade Canyon and Emigrant Canyon being the major constriction points along the Humboldt River Valley. The upper basin begins in northeastern Nevada and drains about 5,000 square miles (13,000 km2) upstream from Palisade. The middle basin has a drainage area of about 7,800 square miles (20,000 km2) and lies between Palisade and Emigrant Canyon, a narrow gap located just downstream from Comus. The lower basin is an area encompassing some 4,100 square miles (11,000 km2) from below Emigrant Canyon and extending through the Humboldt Sink in northwestern Nevada.[14]

A hydrologic definition instead divides the Humboldt River drainage into two basins—one above and one below Palisade—based on flows that increase above and decrease below this part of the river. The river in the upper basin is 92 miles (148 km) long and in the lower basin it is 218 miles (351 km) long. The major tributaries of the upper Humboldt River basin are (heading downstream) Bishop Creek,

Maggie Creek,[17] and Marys Creek; and of the lower basin they are Pine Creek, Reese River, and the Little Humboldt River.[14]

The source of the main stem of the river is a spring called Humboldt Wells at the northern tip of the East Humboldt Range, just outside the city of Wells. The river flows west-southwest through Elko County past the communities of Elko and Carlin. Approximately 15 miles (24 km) upstream from Elko, the river receives the North Fork of the Humboldt River and receives the South Fork approximately 7 miles (11 km) downstream of Elko.

In northern Eureka County it passes through Palisade Canyon between the south end of the Tuscarora Mountains and the north end of the Shoshone Range. At Battle Mountain the river turns northwest for approximately 50 miles (80 km), then west at Red House and past Golconda and a spur of the Sonoma Range. It merges with the Reese River near Battle Mountain and receives the Little Humboldt River approximately 5 miles (8 km) upstream from Winnemucca.

Past the junction with the Little Humboldt, the river turns southwest, flowing past Winnemucca and through

Rye Patch Dam impounds the river, forming the Rye Patch Reservoir, which stores water to irrigate farms near Lovelock, 22 miles (35 km) downstream.[18] The Humboldt empties into an intermittent lake in the Humboldt Sink on the border between Pershing and Churchill counties, approximately 20 miles (32 km) southwest of Lovelock.[19]

The river gains most of its water from snowmelt in the mountains in the eastern part of the watershed, most importantly the Ruby Mountains, Jarbidge Mountains, and Independence Mountains. River flow generally decreases downstream to the west, partly due to water removal from the river for irrigation, especially near Lovelock. Stream-gauge measurements undertaken by the United States Geological Survey suggest that Palisade Canyon, between Carlin and Beowawe, is the point where the river's flow ceases to increase and begins to decrease. Also, since the Humboldt's water comes almost exclusively from snowmelt, its flow is highly variable from season to season (peak flow occurs during the spring melt) and from year to year (depending on the amount of snow every winter)[2][14]

Ecology

Lahontan Cutthroat Trout

The

meristic studies of LCT indicate that the Humboldt River Basin LCT is a unique subspecies of cutthroat trout.[20]

North American Beaver

Newmont's shallow groundwater monitoring wells along Maggie Creek have shown about a 2-foot (0.6 m) rise over the past 17 years along Maggie Creek. Stream flows are more perennial, making more water available for wildlife and livestock and protecting populations of native trout.[21] Maggie Creek has a Beaver Creek tributary which flows from Beaver Peak in the Tuscarora Mountains.[22][23][24]

Environmental aspects

Humboldt River Course Map

The Humboldt River and its surrounding areas have raised some concern about the increasing levels of toxic elements such as arsenic and mercury. These elements are showing up in fish and other wildlife that consume the water. The quantity being absorbed by fish specifically is not of concerning levels though. Brumbaugh and May took samples of fish from the south fork of the Humboldt River. They determined mercury levels within the fish were between 0.061 and 0.082 micrograms per gram of flesh.[25] This is well below the EPA's guideline of 0.30 micrograms per gram.[25] However, though low levels are found in animals, many people are concerned that drinking water and surrounding land is still contaminated. They believe the contamination came from prior mining excursions. Mercury was commonly mined in the area and so was gold.[26] Whether it was leaching from the gold mining process or leftover mercury ore, these toxic elements entered the environment and waterway. Since then, these levels have gone down considerably. The U.S. Geological Survey and other committees conducted a couple of surveys to determine the safety of the drinking water. In 1962 the Water Resources Bulletin, out of Carson City, conducted one of the first main tests. This preliminary test was to determine every mineral, element and ion present.[27] The next big test was done in 1985 by the U.S. Geological Survey. They took samples from a much more local area and determined concentrations were high, but not abnormally high.[28] Another more recent test, which was done in 2002, was specifically on mercury being leached from abandoned mines. However, this test determined that mercury levels dropped off very quickly the further away the tests were done.[29] Finally, the most recent study, done in 2019, was an extremely comprehensive test which included samples from numerous places throughout the river's path. This test was based out of the University of Nevada Reno and determined what elements and minerals were present. It also determined that toxic element concentrations were fairly consistent.[30] This means that while these elements are present, they do not pose a severe threat.
