  ## Geography and Ecology
  
  Severka is located 16 km south of Klyuchi (the district's administrative centre) by road. Novovoznesenka is the nearest rural locality. Between Severka and the nearby border with Kazakhstan there is a Lake named Petokhovo (Ozero Petuhovskoe, Russian: озеро Петуховское), which is a hypersaline soda lake. Metagenomic analyses of lake samples collected in July 2016 indicate the presence of archaea belonging to the Lokiarchaeota group (MAG: Ca. Lokiarchaeota archaeon isolate CSSed165cm_327R1) among other microbes.
