Why Mallorca's reservoirs remain empty despite rain — a reality check

Answer

Why doesn’t rainfall in the Serra de Tramuntana fill Mallorca’s reservoirs properly?

Rain in the Serra de Tramuntana does not always translate into usable reservoir water. A large share can evaporate or flow away before it reaches the storage and supply network. In practice, the place where rain falls is not always the place where Mallorca needs the water most.
