Desert wells generate only in desert biomes. They have a 1⁄1000 chance to be generated in any desert chunk, which makes them a rare sight. It is possible for a well to generate around a cactus. The well structure will still generate with the "Generate Structures" option disabled.
It is common to find two desert wells spawning in the same chunk.[Bedrock Edition only]
