Lake Poway is a dam and reservoir in Poway, California, United States. The dam is owned by the City of Poway and was constructed between 1970 and 1972 with the purpose of storing and supplying water, and providing recreational facilities to the community. A $3.2-million bond issue for construction of the dam was rejected by voters in 1964 and 1966, but passed with 87 percent in favor in 1969. Year-round fishing for trout, bass, catfish, sunfish and bluegill is available at the lake.

History

In 1962, a report showed that Poway's existing storage facilities were insufficient in the event of a breakdown of the aqueduct from the Colorado River following an earthquake or other interruption to the supply. As a result, it was proposed that an earthen dam be built in Warren Canyon to impound water and form a storage reservoir. Funds for the project were to come from a bond issue and the matter came to a vote in March 1964. In this first vote and a second attempt in June 1966, the measure received the support of most voters, but failed to reach the required two-thirds majority. Finally, in June 1969, a $3.2-million bond was passed with 87 percent in favor. Groundbreaking took place in December 1970, with water flowing into the dam in late 1971. Recreational facilities were built in 1972, and opened in October of that year.{{cite web |last1=Shepardson |first1=Mary |title=Third time was the charm for Lake Poway |url=https://www.sandiegouniontribune.com/pomerado-news/opinion/editorial/then-and-now/sd-shepardson-third-time-charm-lake-poway-20171103-htmlstory.html |website=San Diego Union Tribune |access-date=June 29, 2020 |archiveurl=https://web.archive.org/web/20200629134417/https://www.sandiegouniontribune.com/pomerado-news/opinion/editorial/then-and-now/sd-shepardson-third-time-charm-lake-poway-20171103-htmlstory.html |archivedate=June 29, 2020 |date=November 4, 2017}}

In 2017, torrential rains caused the reservoir water level to near the top of the dam, but a spillover did not occur and it remained structurally sound.{{cite web|last1=Dreyer|first1=Steve|date=March 1, 2017|title=City monitoring Lake Poway reservoir level|url=https://www.sandiegouniontribune.com/pomerado-news/news/local-news/poway/sd-city-monitoring-lake-poway-level-20170301-story.html|url-status=live|archiveurl=https://web.archive.org/web/20200629021854/https://www.sandiegouniontribune.com/pomerado-news/news/local-news/poway/sd-city-monitoring-lake-poway-level-20170301-story.html|archive-date=June 29, 2020|access-date=June 29, 2020|website=San Diego Union Tribune}}

In 2019, Poway experienced a water quality event. A precautionary boil water advisory was issued and the San Diego County Department of Health forced restaurants and other businesses to shut down for a week.{{Cite web|last=Hoffman|first=Matt|date=December 6, 2019|title=Poway Businesses Hurting In Midst Of Water Crisis|url=https://www.kpbs.org/news/2019/dec/06/poway-businesses-hurting-after-water-contamination/|url-status=live|archive-url=https://web.archive.org/web/20200629143818/https://www.kpbs.org/news/2019/dec/06/poway-businesses-hurting-after-water-contamination/|archive-date=June 29, 2020|access-date=June 29, 2020|website=KPBS Public Media|language=en}} The problem started when a storm water pipe backed up during strong rains on the November 28 and 29.
