Desna River
Within the city the Dnieper River forms a branching system of tributaries, isles, and harbors within the city limits. The city is close to the mouth of the Desna River and the Kyiv Reservoir in the north, and the Kaniv Reservoir in the south. Both the Dnieper and Desna rivers are navigable at Kyiv, although regulated by the reservoir shipping locks and limited by winter freeze-over.
