Which condition exists when the rates of water flowing into and out of a lake are balanced so that the lakes depth appears to be constant?

The condition in which the rates of water flowing into and out of a lake are balanced, resulting in a seemingly constant lake depth, is known as hydrological equilibrium or steady-state condition. In this state, inflows from sources such as rivers, precipitation, and groundwater are equal to outflows through evaporation, seepage, or water extraction. This balance maintains the lake's water level over time, despite natural variations in weather or water usage.
