Hydrology

The Kola Peninsula has many small but fast-moving rivers with rapids. The most important of them are the Ponoy, the Varzuga, the Umba, the Teriberka, the Voronya, and the Yokanga. Most rivers originate from lakes and swamps and collect their waters from melting snow. The rivers become icebound during the winter, although the areas with strong rapids freeze later or not at all.

Major lakes include Imandra, Umbozero, and Lovozero. There are no lakes with an area smaller than 0.01 square kilometers (0.0039 sq mi). Recreational fishery is developed in the region.
