Lake Havasu ({{IPAc-en|ˈ|h|ɑː|v|ə|s|uː}}) is a large reservoir formed by Parker Dam on the Colorado River, on the border between San Bernardino County, California, and Mohave County, Arizona. Lake Havasu City sits on the Arizonan side of the lake with its Californian counterpart of Havasu Lake directly across the lake. The reservoir has an available capacity of {{convert|619400|acre.ft|km3}}. The concrete arch dam was built by the United States Bureau of Reclamation between 1934 and 1938. The lake's primary purpose is to store water for pumping into two aqueducts. Prior to the dam construction, the area was home to the Mojave people. The lake was named (in 1939) after the Mojave word for blue.{{Cite book|last=Gudde|first=Erwin G.|title=1000 California Place Names|year=1959|publisher=University of California Press|location=Los Angeles|page=[https://archive.org/details/1000californiapl00gudd/page/33 33]|edition=3rd|isbn=0-520-01432-4|url-access=registration|url=https://archive.org/details/1000californiapl00gudd/page/33}} In the early 19th century, it was frequented by beaver trappers.{{Citation needed|date=February 2017}} Spaniards also began to mine the areas along the river.{{Citation needed|date=February 2017}}

Aqueducts

Mark Wilmer Pumping Plant pumps water into the Central Arizona Project Aqueduct. Whitsett Pumping Plant is located on the lake, and lifts the water {{convert|291|ft}} for the Colorado River Aqueduct. Gene Pumping Plant, south of Gene Wash Reservoir, is west-southwest of Parker Dam and gives the water an additional boost of {{convert|303|ft}}. The Colorado River Aqueduct has three more pumping plants: Iron Mountain ({{convert|144|ft}}), Eagle Mountain ({{convert|438|ft}}), and Julian Hinds ({{convert|441|ft}}). The total lift is {{convert|1617|ft}}.{{Citation needed|date=January 2021}}

Natural history

The shorelines are in the ecotone (transition zone) of the higher Mojave Desert to the lower Sonoran Desert and its Californian Colorado Desert ecoregions.{{Citation needed|date=January 2021}}

Havasu National Wildlife Refuge is located at the upper end and upriver. Lake Havasu State Park is along the eastern shore in Arizona. The Bill Williams River National Wildlife Refuge extends southeastward up the riparian zone of the Bill Williams River canyon from the southeastern end of the reservoir and dam.{{Citation needed|date=January 2021}}

Lake Havasu is well known for its recreational fishing and boating, which bring in about a million visitors a year.{{cite web | url= http://www.golakehavasu.com | title = About Lake Havasu City| website= golakehavasu.com| publisher = Lake Havasu City Convention & Visitors Bureau| date = | accessdate = September 3, 2023}} Fishing tournaments are often held on the lake, where bass are the main catch.{{Citation needed|date=January 2021}}

Fish list : Largemouth bass, smallmouth bass, striped bass, carp, channel catfish, flathead catfish, crappie, razorback sucker, sunfish, and redear sunfish.{{Citation needed|date=January 2021}}

White sturgeon were stocked in Lake Havasu in 1967 and 1968 from stock obtained from San Pablo Bay, California. While some dead sturgeon were found downstream from Havasu (probably killed during passage over dams), living fish have not been recorded, but may still exist along the southern end of Lake Havasu near Parker Dam.{{cite web| url = https://nas.er.usgs.gov/queries/FactSheet.asp?speciesID=300| title = Acipenser transmontanus| access-date = 2008-01-05| archive-date = 2007-07-13| archive-url = https://web.archive.org/web/20070713192652/http://nas.er.usgs.gov/queries/FactSheet.asp?speciesID=300| url-status = dead}}

The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating [https://oehha.ca.gov/advisories/lake-havasu advisory] for Lake Havasu based on levels of mercury found in fish caught from this water body.{{Cite news|url=https://oehha.ca.gov/advisories/lake-havasu|title=Lake Havasu|last=Pham|first=Huyen Tran|date=2017-01-24|work=OEHHA|access-date=2018-06-13|language=en}}
