Negative weather conditions during dangerous autumn and winter period, accompanied with strong wind, such precipitations as wet snow, snowstorm with icy ground, as well as minimal water temperature on the republic’s waters increase risk of occurring accidents with small vessels. On the river Kama (up to the river Volga estuary) vessels navigation is closed from November 10. From November 20 to 24 works on finishing vessels navigation on the Volga and Kama lower the river Vyatka estuary will begin.
