watershed san joaquin river watershed tulare basin watershed two river systems drain and define the two parts of the central valley the sacramento river along with its tributaries the feather river and american river flows southwards through the sacramento valley for about 447 miles 719 km 34 in the san joaquin valley the san joaquin river flows roughly northwest for 365 miles 587 km picking up tributaries such as the merced river tuolumne river stanislaus river and mokelumne river 35 the central valley watershed encompasses over a third of california at 60 000 square miles 160 000 km 2 with 46 percent draining into the sacramento river 26 percent into the san joaquin and 27 percent into tulare lake in the southern part of the san joaquin valley the alluvial fan of the kings river and another from coast ranges streams have created a divide the dry tulare basin of the central valley receives flow from four major sierra nevada rivers the kings kaweah tule and kern this basin usually endorheic formerly filled during snowmelt and spilled out into the san joaquin river called tulare lake it is usually dry because the rivers feeding it have been diverted for agricultural purposes 36 central valley rivers converge in the sacramento san joaquin delta a network of marshy channels distributaries and sloughs that wind around islands mainly used for agriculture there the rivers merge with tidewater and eventually reach the ocean after passing through suisun bay san pablo bay upper san francisco bay and finally the golden gate many of the islands lie below sea level because of intensive agriculture and face a high risk of flooding which would allow salt water to rush back into the delta especially when too little fresh water is flowing in from the valley 37 the sacramento river carries far more water than the san joaquin with an estimated 22 million acre feet 27 km 3 of virgin annual runoff as compared to the san joaquin s approximately 6 million acre feet 7 4 km 3 intensive agricultural and municipal water consumption decreased the rate of outflow to about 17 million acre feet 21 km 3 for the sacramento and 3 million acre feet 3 7 km 3 for the san joaquin these figures vary widely from year to year over 25 million people living in the valley and other regions of the state rely on the water carried by these rivers 38 river engineering edit sierra nevada runoff provides one of california s largest water resources the sacramento river is the second largest river to empty into the pacific from the contiguous united states behind only the columbia river and greater than the colorado river 39 combined with the fertile and expansive area of the central valley s floor the central valley is ideal for agriculture 40 the central valley is one of the united states most productive growing regions this is made possible by engineering the watercourses to prevent flooding during the spring snowmelt and drying up in the summer and autumn 41 many dams including shasta dam oroville dam folsom dam new melones dam don pedro dam hetch hetchy dam friant dam pine flat dam and isabella dam were constructed on the rivers with many of them being part of the central valley project 41 these dams impact physical economic cultural and ecological resources for example enabling the development of its vast agricultural resources but leading to the loss of the chinook salmon 42 post world war ii demand for urban development most notably the san francisco bay area and the los angeles inland empire san diego required water resources moreover agriculture in the southern central valley required far more water than was available locally the feather river in the sacramento valley was looked to as a water source leading to the california state water project this transports water to the southern san joaquin valley and urban areas south of the tehachapi mountains 43 runoff from the sacramento and san joaquin rivers is intercepted in the delta through a series of pumps that divert water into the california aqueduct which runs south along the length of the san joaquin valley 44 in parallel pumps divert water into the delta mendota canal the flow of the sacramento river is further supplemented by a tunnel from the trinity river a tributary of the klamath river northwest of the sacramento valley near redding 45 cities of the san francisco bay area also needing water built aqueducts from the mokelumne river and tuolumne river that run east to west across the middle part of the central valley 46 47 flooding edit this section needs more citations

valley lowlands are prone to flooding especially in the old tulare lake buena vista lake and kern lake rivers the kings kaweah tule and kern rivers originally flowed into these seasonal lakes which would expand each spring to flood large parts of the southern san joaquin valley farms towns and infrastructure in these lakebeds are protected with levee systems while the risk of floods damaging properties increased greatly the great flood of 1862 was the valley s worst flood in recorded history flooding most of the valley and putting some places as much as 20 feet 6 1 m under water in 2003 it was determined that sacramento had both the least protection against and nearly the highest risk of flooding congress then granted a 220 million loan for upgrades in sacramento county 48 other counties in the valley that often face flooding are yuba stanislaus and san joaquin landslides edit a very strong positive correlation exists between rainfall and slow moving landslides in northern california especially in the central valley region changes in climate and precipitation levels have shown that consistent average rainfall has increased the number and intensity of landslides within the past 5 6 years this information was shown in a study that focused on the behavior of these slow moving landslides and how their nature changed with years of extreme average rainfall versus minimal average rainfall in 2016 the average annual precipitation levels were lower because of a drought that was coming to an end at that time the minimal rainfall in that year showed that 119 landslides had been moving comparatively in 2017 there were very extreme levels of precipitation in the central valley which cause 312 landslides to move that year 49 slow moving landslides are impacted even if the intensity of the rainfall is not as severe consistent moderately intense rainfall increases the saturation of water in the ground this over saturation is what causes the movement of a slow moving landslide rather than the more quick moving and rigorous landslides that also occur in this region of california quick moving landslides are caused by very intense rain or sometimes earthquakes that make a greater difference in the land in a shorter amount of time according to a survey paper written in 1988 about a storm that occurred in 1982 in the central valley region rainstorms that can cause that type of landslide to happen about every 5 years landslides to higher degrees such as the ones that happened due to the 1982 storm only occur every 20 to 100 years this intense storm in the san francisco bay area caused a lot of damage as a result of moving debris and landslides they caused damage to the land and put people living in these areas that are susceptible to these disasters in great harm the aftermath of this storm involved millions of dollars in retributions to restore the land and surrounding areas it also led people to make greater efforts into planning around the danger of these landslides as in how to manipulate the land to accommodate the consequences droughts edit see also climate change in california out of the past twenty two years when california has experienced significant drought conditions for thirteen years from 2000 to 2018 was the second driest period that california has ever experienced the driest three year period ever in california was from 2012 to 2014 three quarters of the state of california is experiencing extreme drought conditions there are also multiple types of droughts such as agricultural droughts meteorological droughts snow droughts and hydrological droughts all of these droughts affect california in different ways droughts can damage forests and can cause wildfires droughts cause forests to become dry which causes trees to die dead trees result in wildfires the u s drought monitor is released every thursday showing which parts of the u s are in a drought it started in 2000 and since then the longest duration of a drought in california lasted a total of 376 weeks it started on december 11 2011 and ended on march 5 2019 the most intense period captured on the drought monitor was on the week of july 29 2014 it showed that 58 41 of california s land was affected by a drought in 2014 2015 farm related losses in california totaled 5 billion and 20 000 farmers also lost their jobs citation needed economy edit agriculture is the primary industry in most of the central valley a notable exception is the sacramento area which hosts a large and stable workforce of government employees despite state hiring cutbacks and the closure of several military bases sacramento s economy has continued to expand and diversify and now more closely resembles that of the san francisco bay area primary sources of population growth are bay area migrants seeking lower housing costs augmented by immigration from asia central america mexico ukraine and the rest of the former soviet union 6 the central valley s high rates of poverty asthma and air pollution have impeded the valley from transforming its economy into relevance beyond its role as an agricultural breadbasket 50 agriculture edit crop fields in the united states the central valley is one of the world s most productive agricultural regions 51 5 more than 230 crops are grown there 5 on less than 1 percent of the total farmland in the united states the central valley produces 8 percent of the nation s agricultural output by value us 43 5 billion in 2013 52 california s farms and ranches earned almost 50 billion in 2018 53 the valley s productivity relies on irrigation from surface water and badly depleted underground aquifers 54 about one sixth of the us irrigated land is in the central valley 55 virtually all non tropical crops are grown in the central valley which is the primary source for produce throughout the united states including tomatoes grapes cotton apricots and asparagus 56 six thousand almond growers produced more than 600 million pounds 270 10 6 kg in 2000 about 70 percent of the world s supply and nearly 100 per...
