It has just now stopped raining in New Orleans and we are one soggy city. My shoes get sucked off if I walk through the front yard to the mailbox.
The entire city is hyped about the Saints football team and no one is all that interested in the health of their ponds. Good thing ponds can tend to themselves for ages with no human interference. In fact, they often do better if we just leave them alone. i suspect that will be the case here if the football team wins tomorrow. And then comes Mardi Gras on February 20th. New Orleans is a constant party from now until Ash Wednesday.
Of course, only half of the population has returned to the city 17 months after Katrina and it may stay that way. But ponds either in someone's yard or abandoned are doing well. After my house was destroyed, it was a year before I could move my pond to my new house. There were about 8" of water in the pond, lots of anacharis and several goldfish. This, with no power and no attention for a year. Ponds are indeed wonderful.
