[15] The Sacramento supports 40–60 species of fish,[88][89] and 218 species of birds. Other pollutant sources include urban runoff, mercury and even rocket fuel that was reported to have leaked near the American River from an Aerojet extraction project. North of Antioch and Pittsburg, the Sacramento and San Joaquin Rivers join at the head of Suisun Bay, marking the official end of both rivers. Amphibians originally thrived in the marshes, sloughs, side-channels and oxbow lakes because of their warmer water, abundance of vegetation and nutrients, lower predator populations and slower current. Whales turn up in Sacramento River . In the east, mercury that permeated into the ground has contaminated several aquifers that feed rivers such as the Feather, Yuba and American. Two wayward humpback whales forged their way up the Sacramento River on Monday, evoking the visit 22 years ago of the Bay Area's most famous marine mammal, Humphrey the humpback whale. A few miles downstream it forms the border of Butte County and Glenn County to the west. The river flows 382 miles (615 km) south-southwest between the Cascade and Sierra Nevada ranges, through the northern section (Sacramento Valley) of the Central Valley. In 2004, only 200,000 fish were reported to return to the Sacramento; in 2008, a disastrous low of 39,000. In the years to come, this path, which eventually extended from San Francisco to Portland, Oregon following parts of the Sacramento, Willamette, Klamath, Rogue, and other rivers would become an important trade and travel route. Whales in Sacramento river. The Sacramento is by far the largest contributor of fresh water to the Delta; in an average year, it accounts for more than 80 percent of the fresh water inflow. At Walnut Grove, the manmade Delta Cross Channel connects the Sacramento to the Mokelumne River channel, allowing a portion of the water to be pumped south toward Clifton Court Forebay, the receiving reservoir for the main CVP and State Water Project aqueducts which irrigate millions of acres and supply water to over 23 million people in the San Joaquin Valley, the San Francisco Bay Area and Greater Los Angeles. Settlement size ranged from small camps to villages of 30–50 permanent structures. Sacramento River Whale. Probably the most famous humpback whale is "Humphrey," who was rescued twice by The Marine Mammal Center and other concerned groups. The Freeport gauge, which sits just downstream of Sacramento, provides a relatively good metric of the annual outflow from the Sacramento River Basin. The Sacramento River watershed includes large areas of coniferous forests in the Mendocino and Trinity National Forests in the Coast Ranges, Shasta and Lassen National Forests in the southern Cascades and the Plumas, Tahoe and Eldorado National Forests on the western slopes of the Sierra Nevada. It’s been 31 years since Humphrey the humpback whale found himself up the Sacramento River, and occasionally dolphins and whales get lost. In 1985 we had Humphrey visit. 2 min read. The water traveled down the Sacramento and washed into the Pacific; the influx of fresh water was such that it confused thousands of anadromous fish to begin migrating up the river, thinking that the river had risen because of late-autumn storms. [49] By this time, California was under the control of Mexico, although few Mexican settlers had come to what would later become the state, mostly settling in the small pueblos and ranchos along the south and central coast. ″We’re talking of weeks, probably. [77][78] In the following decades, more huge reservoirs – capable of storing a combined 13×106 acre feet (16 km3) of water – were constructed on the Sacramento's main tributaries, enabling the regulation of water for irrigation and hydroelectric power. This can't happen, can it? [51][52][53], After the Bear Flag Revolt of 1846 and the Mexican–American War, in which California became part of the United States, Sutter and other large landholders in California held on to their properties. The animal was first sighted in San Francisco Bay on Friday. They also hunted waterfowl, antelope and deer which all existed in huge numbers in the rich valley bottom and marsh lands. The duo, generally believed to be mother and calf (Delta, the mother and Dawn, her calf), continued to swim upstream to the deep water ship channel near West Sacramento, about 90 miles (140 km) inland. The watershed also has Lassen Volcanic National Park, which covers 106,000 acres (430 km2) centered on Lassen Peak, the southernmost Cascade volcano. [10], Below Rio Vista, the lower Sacramento River is rejoined by the Deep Water Ship Channel and the Yolo Bypass and curves southwest along the base of the Montezuma Hills, forming the border of Solano and Sacramento Counties. Whale Watch in Sacramento on YP.com. [66], It was not long after Sacramento surpassed a population of 10,000, then the Great Flood of 1862 swept away much of it (and almost everything else along the Sacramento River) and put the rest under water. The Goose Lake watershed is the only part of the Sacramento River basin extending into another state. In the following years, two more Spanish expeditions traversed the lower part of the river, the last one in 1817. [10], Below Shasta Dam the Sacramento River enters the foothills region of the northern Sacramento Valley. For most of the year, the bypasses remain dry and are used for annual crops such as rice. Abundant salmon and steelhead runs in the Sacramento River and its tributaries were harvested using fishing weirs, platforms, baskets and nets. They assumed that the San Joaquin, coming from the south, was the largest of the merging rivers they saw. The river flows at an elevation somewhat higher than the surrounding terrain due to deposits of sediment over millennia that created raised banks (essentially natural levees). While it intended to contain minor floods in the river banks by strengthening the existing levee system, the main feature was a series of bypasses, or sections of the valley intentionally designed to flood during high water. [73] Starting in the late 1950s, two major canals were extended to irrigate the western side of the Sacramento Valley – the Tehama-Colusa and Corning Canals. For the river in Mexico, see, Sacramento River from the old pumping station in. Here are 10 of the world's most famous whales. However, this pair is 90 miles from the Pacific Ocean! [11] Unlike most California rivers, the Pit and the McCloud Rivers are predominantly spring-fed, ensuring a large and consistent flow in even the driest of summers. The Great Whale River (French: Grande rivière de la Baleine) is a river in Nunavik, Quebec, Canada.It flows from Lac Saint-Luson through Lac Bienville west to Hudson Bay. In the 19th century, gold was discovered on a tributary of the Sacramento River, starting the California Gold Rush and an enormous population influx to the state. Dams, levees and floodways constructed during the 20th century have thus far prevented this phenomenon from re-occurring. The Yolo Bypass, located on the west side of the river, starts at the confluence of the Feather and rejoins the Sacramento in the Delta. That would be less likely in the ship channel than in the undredged river farther up, or the many sloughs in the Delta. The dam has also become a "favorite spot" for predatory fish to congregate, feasting on the salmon that get trapped both above and below the dam. A tank car split open, spilling about 19,500 gallons of the pesticide metam sodium into the river. The river is considered one of the best salmon habitats in the watershed because of its relatively cold water and the availability of ideal habitat such as gravel bars. Other human impacts include the heavy water consumption for agriculture and urban areas, and pollution caused by pesticides, nitrates, mine tailings, a… Initial Notification: On 14 May 2007, two humpback whales (Megaptera novaeangliae) were observed within the Sacramento River upstream of Rio Vista, CA. [107] By May 30, 2007, the cow and calf apparently slipped out unnoticed under the Golden Gate Bridge into the Pacific Ocean, likely under cover of night. They said it was tapes of other hump-back whales eating, and it chased them the other way. This has resulted in a ban on coastal salmon fishing for several years since 2002. The Central Valley Project, one of the largest irrigation projects in the world, was constructed by the U.S. Bureau of Reclamation beginning in 1935. In 2010, about 100 miles (160 km) of the river's riparian forests are undergoing active restoration. [64] As the economy of the Sacramento Valley grew, the Southern Pacific Railroad established tracks along the river to connect California with Oregon following the ancient path of the Siskiyou Trail, in the 1880s and 1890s. The San Joaquin River watershed occupies two-thirds to three-quarters of northern California's land, but only collects one-third to one-quarter of the precipitation. Since the 1950s the watershed has been intensely developed for water supply and the generation of hydroelectric power. Since the 19th century, artificial levee systems have been constructed to enable farming in the fertile flood plain. [12] The Upper Sacramento River canyon also provides the route for I-5 and the railroad between Lakehead and Mount Shasta. Late summers of particularly dry years could see flows drop below 1,000 cubic feet per second (28 m3/s). Near downtown Sacramento it receives the American River from the east, then passes under the historic Tower Bridge and Interstate 80 Business. [72], In 1873, Colonel B.S. Rescuers downstream broadcast sounds of humpback whales feeding to draw the whale back to the ocean. [81][82], Over the years, several other plans materialized to divert rivers from California's North Coast into the Sacramento watershed, as future demand was projected to exceed supply. [89], Starting in the 20th century, dam construction blocked off hundreds of miles of salmon-spawning streams, such as the upper Feather and American Rivers, and the entirety of the Pit and upper Sacramento rivers. [84] Similarly, the Dos Rios Dam project would have diverted a considerable portion of the Eel River to the Sacramento. The first rescue was in 1985, when he swam into San Francisco Bay and then up the Sacramento River to Rio Vista. Pollution from farms and urban areas took a heavy toll on the river's environment, and heavy irrigation withdrawals sometimes resulted in massive fish kills. [74], The Sacramento River Flood Control Project was authorized by the federal government in 1917. [9] Rising in the Klamath Mountains, the river flows south for 400 miles (640 km) before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay. Never thought I’d see a 55 ton whale where I used to fish in 30 feet of fresh water 100 miles inland. The highest recorded flow was 374,000 cubic feet per second (10,600 m3/s) on February 20, 1986. Annual depletions (water not returned to the river after use) are about 4.72 million acre feet (5.83 km3) for irrigation and 491,000 acre feet (0.606 km3) for urban use. Saltwater intrusion from the Pacific Ocean was one of the main reasons for the construction of the federal Central Valley Project (CVP), whose dams maintain a minimum flow in the Sacramento to keep seawater at bay. [17] The ones currently in operation are at Delta, California (near the source at Mount Shasta), at Keswick (near Redding), Colusa (about halfway down the river), Verona, and Freeport. In 1808, explorer Gabriel Moraga, on a journey to find suitable sites for the construction of missions, became the first foreigner to see the river clearly. [35], As the Sierra rose, water erosion and glaciation carved deep canyons, depositing massive amounts of sediment to form a coastal plain between the mountains and the Pacific Ocean. A total of 461 people were forced from their homes, but only 277 made it to the reservation; the others perished of disease, starvation or exhaustion. The basin's diverse geography ranges from the glacier-carved, snowcapped peaks of the Sierra Nevada to the sea-level (and often lower) marshes and farmlands of the Sacramento-San Joaquin Delta. Next, the green glob entered Shasta Lake, California's largest reservoir. The tank car carrying the metam sodium through California was of a type that the National Transportation Safety Board said had "a high incidence of failure" in accidents. MAY 15, 2007-If you live by the sea whale sightings are no big deal. [6] Flow in the Yolo Bypass, a relief channel designed to carry a portion of the flood waters in order to protect the Sacramento area, is not measured by the Freeport gauge. Because of inadequate design, roughly 25–40% of the incoming fish get blocked by the dam each year. Sacramento River Humpback Whales 183 were observed in the same area (Scheffer & Slipp, 1948). Controlling runoff from the upper 6,600 square miles (17,000 km2) of the Sacramento River watershed, Shasta greatly reduces flood peaks on the middle and lower parts of the Sacramento River. The McCloud River rises on the east slope of Mount Shasta and flows south for 77 miles (124 km) through the southern Cascade Range, roughly parallel to the Upper Sacramento, eventually to reach the McCloud Arm of Shasta Lake. [106], On May 14, 2007, onlookers and media spotted two humpback whales traveling the deep waters near Rio Vista. Pesticide runoff, especially DDT, is one of the largest problems faced today, because of the valley's primarily agricultural economy. As the river continues south it approaches the Sacramento metro area, the largest population center in the watershed. Many Sacramento River fish species are similar to those in the Snake–Columbia River systems; geologic evidence indicates that the two were connected by a series of wetlands and channels about 4-5 million years ago. [94], Riparian and wetlands areas along the Sacramento once totaled more than 500,000 acres (2,000 km2); today only about 10,000 acres (40 km2) remains. [100][101], By the late 20th and early 21st centuries, the government blamed crashing fish populations on overfishing, especially off the Northern California and Oregon coast, which lie directly adjacent to the migration paths of Sacramento River salmon. Construction of Shasta Dam, the principal water storage facility in the Sacramento River system, started in 1938 and was completed in 1945. Due to the reclamation of land for agriculture and the regulation of seasonal flooding, the amount of water-based habitat declined greatly during the 20th century. An additional 7.61 million acre feet (9.39 km3) is reserved for environmental uses, primarily to maintain a minimum fresh water outflow in the Delta to combat salinity. About 650,000 years ago the lake catastrophically overflowed, draining into San Francisco Bay and creating the Carquinez Strait, the only major break for hundreds of miles in the Coast Ranges. For about 12,000 years, humans have depended on the vast natural resources of the watershed, which had one of the densest Native American populations in California. It doesn't get more iconic than Moby Dick, the subject of Herman Melville's classic story … The average flow between 1949 and 2013 was 23,330 cubic feet per second (661 m3/s). Quick Guide & Transcript: Fighting erupts in Tripoli, Whales stranded in Sacramento River. Quick Guide. They've been trying to lure them back to the ocean. This population once included several species of frogs and salamanders; the foothill yellow-legged frog and western spadefoot are listed as endangered species.
