Answer:

How do droughts happen? Droughts happen when there is not enough rain for a long period of time. It's not like a dry spell - there is so little precipitation (rain, snow, sleet or any kind of moisture) that a whole region starts to dry out

Answer:

When rainfall is less than normal for a period of weeks to years, streamflows decline, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water-supply problems develop, the dry period can become a drought.
