The Upper Yarra Reservoir is located east of Melbourne, Victoria, Australia, beyond Warburton within the locality of Reefton. Water from Upper Yarra Reservoir supplies towns in the upper Yarra Valley, and Silvan Reservoir, which transfers water to most parts of Melbourne.

The management of 157,000 hectares of Melbourne's forested water catchments of the Upper Yarra such as the Watts (Maroondah) were vested in the Melbourne and Metropolitan Board of Works (MMBW) in 1891. In 1928, the Upper Yarra catchment was permanently added for water supply purposes.{{cite news|date=25 February 1928|title=UPPER YARRA WATERSHED.|page=3|newspaper=Healesville and Yarra Glen Guardian|location=Victoria, Australia|url=http://nla.gov.au/nla.news-article60293896|access-date=4 March 2017|via=National Library of Australia}}{{Cite book|last=Moulds|first=F.

Approval to construct Upper Yarra Reservoir was granted in the early 1940s but due to World War II work did not start until 1948.{{cite news |url=http://nla.gov.au/nla.news-article205665623 |title=Our Water Supply |newspaper=The Age |issue=30,142 |location=Victoria, Australia |date=6 December 1951 |access-date=4 March 2017 |page=2 |via=National Library of Australia}}, ...They planned to use the Upper Yarra catchment, but, suddenly the demands of War halted their plans...{{cite news|date=10 April 1940|title=UPPER YARRA RESERVOIR|page=2|newspaper=The Argus|issue=29,214|location=Victoria, Australia|url=http://nla.gov.au/nla.news-article12444971|access-date=4 March 2017|via=National Library of Australia}}{{cite news |url=http://nla.gov.au/nla.news-article204425078 |title=UPPER YARRA DAM PROJECT |newspaper=The Age |issue=26,495 |location=Victoria, Australia |date=16 March 1940 |access-date=4 March 2017 |page=30 |via=National Library of Australia}} When the Upper Yarra Reservoir was completed the total storage capacity of Melbourne's system was tripled to nearly 300,000 megalitres.

Upper Yarra Reservoir is also supplied by water transferred from the Thomson River Dam.{{Cite web |title=Thomson Reservoir {{!}} Melbourne Water |url=https://www.melbournewater.com.au/water-data-and-education/water-storage-levels/water-storage-reservoirs/Thomson |access-date=2022-08-23 |website=www.melbournewater.com.au}}

As of January 2007, severe drought in south-eastern Australia had resulted in low water levels in the reservoir, which on 5 January 2007 was approximately half full. As of 22 July 2013, it contained 95,568 megalitres of water(47.6% full).[https://www.melbournewater.com.au/whatwedo/supply-water/reservoirs/Pages/Upper-Yarra-Reservoir.aspx Melbourne Water – Upper Yarra Reservoir] The recorded water storage level in the dam in 26 September 2021 was 186,060 megalitres, equivalent to being 92.8 per cent full.{{Cite web|title=Water storage levels {{!}} Melbourne Water|url=https://www.melbournewater.com.au/water-data-and-education/water-storage-levels#/|access-date=2021-09-26|website=www.melbournewater.com.au}}
