It depends on the weather. In dry weather levels of lake water may go down, and in times of rainfall the levels may rise. (Streams leaving a lake mean that the levels can never rise above that stream level, of course.)

A river can form through ice melting from the mountains or through rainfall that collects in wetlands. Small streams that flow downhill join up and make larger streams which also combine to form rivers.
There are four different stages. These are : Evaporation, Condensation, Precipitation and Collection.

Forest streams are generally streams that are found in and run through a forest. These are waterways that are important to the ecosystem.

When a wet towel is left in the sun it eventually becomes dry, it is dried through the process of evaporation.
Evaporation is faster at high temperature.
Perspiration is when animals, such as humans, sweat and release water back into the atmosphere as vapor. It is part of the evaporation portion of the water cycle, along with of course evaporation, and transpiration (evaporation through plants' leaves).
