Abstract
The results of long-term measurements of the velocities of currents during the ice seasons of 1994–1997, 1999 and 2002, obtained during expeditions of the Laboratory of Hydrophysics, NWPI KarRC RAS to small shallow Lake Vendyurskoe (southern Karelia) have been summarized in the database “Currents in a shallow lake – 1” (Certificate of state registration № 2018621066, date of registration July 13, 2018). The database contains information on the bathymetry of the lake; the locations of measurement stations are mapped. The database contains three types of data: vertical profiles of current velocities at stations in the central basin, long-term measurements of velocities for 1.5–7 days, and short-term measurements for 3–17 hours at different depths in different parts of the lake with a time interval of 1–30 seconds. The total number of measurement stations is 15, the number of measurement series is more than 200. Also, the database contains data on water temperature at the depths of current measurements, and observations of vertical and horizontal ice displacements. A description of the instruments with which the measurements were performed is provided. The database is a set of hyperlinked web pages created in HTML. The structure of the database allows constructing various queries for the analysis of lake currents during the winter period. Its main function is to analyze currents in a small lake during the ice-covered period. The database can be used for scientific purposes by hydrologists, hydrophysicists, or as visual learning aid at geographical and hydrometeorological universities.

Summary
Измерения проводились в зимние месяцы на небольшом мезотрофном озере Вендюрском, расположенном в южной части Карелии (62°10ʹ–62°20ʹN, 33°10ʹ–33°20ʹE) Площадь зеркала озера 10,4 км, объем вод ~ 5,5·107 м3, средняя глубина 5,3 м, максимальная 13,4 м, площадь водосборного бассейна 82,8 км. Песчаные донные отложения преобладают на глубинах до 2–3 м, глубже распространены илы, достигающие метровой толщины в центральной котловине озера. А также вертикальных и горизонтальных смещений льда проводились на 15 станциях двух поперечных разрезов Position of the stations for current measurement in Lake Vendyurskoe in 1994–1997, 1999 and 2002. Точность и разрешающая способность приборов, использовавшихся для измерения течений и смещений льда.
