Cyprus suffers from a chronic shortage of water. The country relies heavily on rain to provide household water, but in the past 30 years average yearly precipitation has decreased. <answer>Between 2001 and 2004</answer>, exceptionally heavy annual rainfall pushed water reserves up, with supply exceeding demand, allowing total storage in the island's reservoirs to rise to an all-time high by the start of 2005. However, since then demand has increased annually – a result of local population growth, foreigners moving to Cyprus and the number of visiting tourists – while supply has fallen as a result of more frequent droughts.
When did Cyprus receive enough rainfall to fill up their water reserves?
Between 2001 and 2004
