392: 468: 554:, which means sea water will begin to flow into the underground water storage areas that were vacated by excess pumping. This can cause decreased water quality and lead to an expensive desalination effort to clean the water before distribution. Water flows through wildlife refuges and national parks can decrease or stop all together due to the decrease of surface and groundwater, the California Water Science Center is a part of a team trying to restore and maintain water flow in these at risk areas. With reduction of water flow and increased windy or dry weather, wildfire risks increase; lightning strikes or accidental human mistake can lead to huge wildfires due to the drier-than-normal climate. 700: 476: 648: 124:
220 years and one for 140 years. The 20th century was fraught with numerous droughts, yet this era could be considered relatively "wet" compared against an expansive 3,500 year history. In recent times, droughts lasting five to 10 years have raised concern, but are not anomalous. Rather, decade long droughts are an ordinary feature of the state's innate climate. Based on scientific evidence, dry spells as severe as the mega-droughts detected from the distant past are likely to recur, even in absence of anthropogenic climate change.

Some local and state governments have resorted to selling water rights for income even when it harms the local community and environment (e.g. taking water away from California and bottling and shipping it to water-rich parts of the United States and the world for profit). This has led many to criticize treating water as a commodity. 691:) and other areas of the state where snowpack is the primary source of river flow, river channels are sized mainly to control snowmelt floods, which do not produce the huge peaks typical of rain floods, but are longer in duration and have a much higher total volume. As a result, reservoirs in this region have very strict restrictions on the amount of water that can be released. An example of a reservoir operated for snow floods is 716:
size of the reservoir, it is difficult to balance the need for winter flood-control space with the need to store water for the summer. This often results in a failure to fill the lake due to a lower than expected spring snowmelt. Water managers and hydrology experts have criticized the outdated, overly conservative operation criteria at Folsom Dam, citing improved weather forecasting and snowpack measurement technology.
22: 723:. If dry weather is forecast, water is allowed to be stored above the legal flood control limit, rather than being wasted downstream. This program is known as "Forecast Informed Reservoir Operations". In addition, capital improvements such as the $ 900 million spillway project at Folsom Dam will allow greater flexibility in water releases, making it safer to maintain a high reservoir level during the wet season. 537:
water will also decrease. With that said the relationship between surface water and groundwater contribute to the hydrologic system, and groundwater helps maintain surface water flows during extended dry periods. With both sources diminishing, the quality and availability of water will decrease. People can become ill from lack of water.

resulting in the temporary evacuation of 200,000 people. The combined inflow to Shasta, Oroville and Folsom Lakes on February 9 was 764,445 acre-feet (0.942929 km). Two days later, the combined flood control release was 370,260 acre-feet (0.45671 km). This water would have been worth $ 370M

There are five major technical categories of drought: (1) Meteorological, (2) Agricultural, (3) Hydrological, (4) Socioeconomic, and (5) Ecological.

functions. Due to the limited capacity of river channels and dam spillways, reservoirs cannot be quickly drained before major storms. This limits how much of a reservoir's capacity can be used for long-term storage. Reservoirs in California are designed to control either rain floods, snowmelt floods

Adaptation is the process of adjusting to circumstances, which means not trying to stop the drought, but trying to preserve the water given the drought conditions. This is the most used option, because stopping a drought is difficult given that it is a meteorological process. Adapting to the problem

Many millions of California trees died from the drought – approximately 102 million, including 62 million in 2016 alone.

near Fresno, which is restricted to about 53 percent capacity well into spring in order to capture summer snowmelt. However, Pine Flat and other San Joaquin reservoirs are frequently ineffectual in controlling rain floods, because they cannot release water fast enough between winter storms.
680:, California's largest reservoir, is limited to approximately 71 percent of capacity in the winter in order to control rain flooding.

Because much of California's water network relies on a system of pumps to move water from north to south, large volumes of water are often lost to the Pacific Ocean during winter storms when river flow exceeds the capacity of the pumps. This is further complicated by environmental rules which

Increasingly dramatic fluctuations in California weather have been observed in the 21st century. In 2015, California experienced its lowest snowpack in at least 500 years; the 2012–15 period was the driest in at least 1200 years. However, the winter of 2016–17 was the wettest ever recorded in
