The odd thing is that Ponce is known for being on the dry side of the island and there has not been any water rationing. It does have three rivers that fill two reservoirs that I know of and they just filled another New reservoir but this one is only for the 100 year floods and is not set up as a water source. The ideal thing is to have a cistern for personal use. When it rains it sometimes comes down in buckets and then a dry period comes along. Short term and long term. The land that we have was once a coffee farm. It was a very productive farm for over a 120 years. This is the beginning of the mountains about 15 minutes from the center of Ponce. When I asked the seller of the farm, who was part of the original family, "why they stopped the coffee farm"? He said, "that the weather changed and it got too dry along with a loss of the market when the US took over.". When I bought the farm about 10 years ago we had a really bad dry spring and the 32 acre farm burnt to the ground, small house and just about everything except a few big trees. Since then each year it seems to be getting wetter and the coqui frogs have moved down the mountains to the farm and in town. I am no weatherman but it looks like this could be a new long term cycle. I think living on an island with unpredictable weather patterns it might be a good idea to invest in a cistern or two.
