No. There are no oceans, rivers, or lakes on Venus.

All of the liquid water on Venus was apparently lost long ago. The solar radiation disassociates water, and the hydrogen was blown off by the solar wind, because Venus has practically no planetary magnetic field. There is still a tiny percentage of water vapor bound as sulfuric acid (rain) in the sulfur dioxide clouds around the planet.

No. The atmosphere of Venus consists mainly of carbon dioxide, and a small amount of nitrogen. The thick cloud cover is composed of sulfur dioxide and sulfuric acid droplets. Due to the dense atmosphere, the surface temperature ranges from 750 to 930 degrees Fahrenheit (398 to 498 Celsius). The surface pressure is 90 times that of Earth. That's like being one kilometer (more than half a mile) under the ocean.

Scientists have yet to figure out planets other than earth with enough water both as liquid and ice to consider it to have a hydrosphere. So no we could not find any planets with a hydrosphere yet.
