A bucket of water, with a lid, decreases in water level to a certain point but then remains at the same water level. Why does the water level remain constant even as the evaporation process continues.

when the water evaporates in the closed container, it can't escape because the lid is on there. Therefore it will reach a point where it can't evaporate anymore, because the rate of evaporation, and rate of condensation will be the same. It will condense at the same speed as it will evaporate, and the water level will stay the same.
if you leave it open, all the water will be gone.

Evaporation and condensation rates are equal. The water vapor pressure above the liquid water has reached saturation level.
