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.

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.
