When a dam is built in a hot, dry area, creating a lake or reservoir above the dam, how does the evaporation from that reservoir affect the environment?

Loss of water from the evaporation and the transpiration in weed-covered of reservoirs can be six times higher than those from normal evaporation in open waters.

Explanation:

This means that more water exposed to the air and the problems of soil such as the sedimentation, siltation, waterlogging, and salinization. Along with the rise in humidity and temperature. Dam walls block the fish from migrating downstream and affect the dissolved oxygen levels of the water along with the physical properties of a reservoir that are not suited to the aquatic plants and animals that evolved with a given river system. The dams also contain invasive species that affect the environment.
