"In this drought, no doubt the water does become more stagnant because the rains which cause our ponds to refresh is not happening.; We are running aerators. However, we are also using the water to water plants including tomatoes which we then eat. We also get the water on us when we irrigate because we are using hoses and pumps that sometimes accidentally spray on us. How concerned should we be about pond water in extreme drought? You have any sources on that. Should people be swimming in ponds when we know the water has not been refreshed by rain on regular basis? I have not been."
As far as necrotizing fasciitis is concerned, lakes and ponds are not the only source. An open wound that comes into contact with any surface on which the bacteria exists (usually a moist surface) is a potential source of infection. Although water quality of ponds may be lessened by the lack of rainfall, your aerators will relieve the stagnation. The relative safety of pond water remains the same whether rain has occurred recently or not. I would not worry about watering your plants with pond water in the slightest. Similarly, the occasional contact with pond water should not be of concern either. Swimming always creates the potential for scraping feet on debris in the pond or other minor abrasions. If concerned about bacteria, either avoid swimming or shower immediately upon finishing your swim.
"I read what Larry Caplan wrote and plant to reprint his advice in the newsletter. I have been soaking my landscaped areas about once a week with pond water. I have a Redbud that is dropping its leaves and has created seed pods. It looks like it would in October. I think it has gone dormant and not died because of the seedpods so I am continuing to water it. I have another tree that is turning orange and will be going dormant I assume. Maybe you have some advice for us about this."
"I have started watering trees that might be at risk but I have too many trees to do this for all of them. Most of my large trees in front of my house are still looking ok. We have some kind of well in front of our house my Dad put in but I do not know if it is a cistern or a well. We just know that a couple years ago during a 2-month dry spell we were going to pump all the water out and could not. Water was running in the bottom from somewhere. The well is about 20 feet deep. Anyway, it still has water and we are thinking about using it for irrigation too."
