Not necessarily. Building reservoirs simply provides the facility for storing rainwater. Its up to the actions of people - in recycling as much water as we can - that will ensure we have a plentiful supply !
CARBON RESERVOIRS - petroleum and coal OXYGEN RESERVOIRS - ice, human body and water
Reservoirs were created to store water for various purposes, such as drinking water supply, irrigation, hydropower generation, and flood control. They help manage water resources, especially in areas with varying water availability throughout the year. Reservoirs can also provide recreational opportunities such as boating and fishing.

Building dams helps prevent erosion by regulating the flow of water in rivers, reducing the speed and volume of water that can cause erosion downstream. Dams also help to stabilize river channels and can create reservoirs that store sediments and reduce erosion. Additionally, controlled release of water from dams can prevent flooding events that can worsen erosion.

The first substance added to water in impounding reservoirs is typically a coagulant, such as aluminum sulfate or ferric chloride. Coagulants help to clump together suspended particles in the water, making it easier to remove them during the water treatment process.
Storing water in reservoirs allows sediments and other particles to settle at the bottom, leading to clearer water at the surface. This settling process helps to naturally purify the water by removing impurities and contaminants. Additionally, the storage time in reservoirs can allow for disinfection processes such as chlorination to take place, further improving water quality.
The purpose of building dams is to control water flow, generate hydroelectric power, provide irrigation for agriculture, manage flooding, and create reservoirs for drinking water supply and recreational use. Dams help regulate water resources and support various human activities while also impacting the environment and aquatic ecosystems.
Energy from the sun drives the water cycle, causing water to evaporate from bodies of water. This water vapor eventually condenses and falls back to the Earth as precipitation, filling reservoirs with freshwater.
Depends on what you do with the water you save or the money saved. Could help, but if you just save it and keep it in North America, no.
They would help to keep the air surrounding full of water vapour so the reservoir would not dry up easily.
