It is located in a glacially-carved valley in [Tongass National Forest](/source/Tongass_National_Forest). It was named ''Ozero Glubokoye'', meaning "deep lake", in 1809 by the Russian navigator [Ivan Vasilyev](/source/Ivan_Vasilyev).<ref name=gnis>{{GNIS|1424779|Redoubt Lake}}</ref>

Redoubt Lake is one of the largest [meromictic lake](/source/meromictic_lake)s in North America. Its water is fresh to a depth of {{convert|330|ft|m|abbr=on}}, below which is a dense, saltwater layer. The lake's maximum depth is {{convert|870|ft|m|abbr=on}} with a mean depth of {{convert|460|ft|m|abbr=on}}. Its surface area covers {{convert|3200|acres|km2|abbr=on}}.<ref name=fs>[http://www.fs.fed.us/r10/tongass/districts/sitka/fwwbs/redoubt_lake/redoubt_lake.shtml Redoubt Lake Sockeye Salmon Enhancement and Monitoring], Tongass National Forest, US Forest Service</ref>  It has been theorized that the lake was once a former fjord that was cut off from the ocean via [isostatic rebound](/source/Isostatic_reboud), leading to seawater being trapped.<ref>{{Cite journal |last=McCoy |first=George A. |date=1977 |title=A reconnaissance investigation of a large meromictic lake in southeastern Alaska |url=https://pubs.usgs.gov/publication/70233527 |journal=Journal of Research of the U.S. Geological Survey |language=en |volume=5 |issue=3 |pages=319–324}}</ref>

In the early 19th century Redoubt Lake was part of [Russian America](/source/Russian_America). The Russians established a small settlement near the lake's outlet known variously as Ozersk Redoubt, Ozyorsk Redoubt,<ref>{{cite book |last= Gibson |first= James R. | title= The Lifeline of the Oregon Country: The Fraser-Columbia Brigade System, 1811-47 |year= 1997 |publisher= University of British Columbia (UBC) Press |isbn= 0-7748-0643-5 |url= https://archive.org/details/lifelineoforegon0000gibs|url-access= registration }}</ref> The Redoubt, Seleniye Dranishnikova, or Dranishnikov Settlement.<ref>{{GNIS|1896937|The Redoubt (historical)}}</ref> Salmon traps were set in the lake and the catch was salted and dried at Ozersk Redoubt. Between 1817 and 1832 the Russians at Sitka and Ozersk Redoubt salted an average of 20,000 salmon annually.<ref>[https://books.google.com/books?id=iyE91cOWY0gC&q=Ozersk+Redoubt&pg=PA47 The fishermen's frontier: people and salmon in Southeast Alaska], by David F. Arnold, William Cronon</ref>

Fish harvests by the Russians at Redoubt Lake sometimes exceeded 50,000 [sockeye salmon](/source/sockeye_salmon) per year. Annual escapements possibly exceeded 100,000 sockeye. In the 1980s, sockeye escapement or returns of adult fish had declined to an average less than 10,000 annually. Some years the numbers measured in the low hundreds.<ref name=fs/>
