The water voles are large voles in the genus Arvicola. They are found in both aquatic and dry habitat through Europe and much of northern Asia. A water vole found in Western North America was historically considered a member of this genus, but has been shown to be more closely related to members of the genus Microtus (Conroy and Cook, 2000; Musser and Carleton, 2005).

Head and body length are 12–22 cm, tail length is 6.5–12.5 cm, and the weight is 70–250 g. The animals may exhibit indeterminate growth. They are thick-furred and have hairy fringe on feet that improves their swimming ability.

Species

• European (or Northern) Water Vole (Arvicola amphibius or Arvicola terrestris)
• Southwestern (or Southern) Water Vole (Arvicola sapidus)
• Montane Water Vole (Arvicola scherman)
