Peter and Dave.
Well, this has been an annual summer event for a long time and summer temps in SD are normally 80-90 in July and August so I guess no blame can be put on global warming. The blame goes to fertilizer both natural and manufactured. Upstream is basically farm land for cattle and crops. So the runoff into the creek is high in nitrogen. The theory from those in the know is that cattails will filter this problem so there will be lots of them planted upstream. The thing is, many years ago when the algae problem started they dredged the west end of the lake which is where the creek comes in. Not knowing at the time, they dredged out many cattails. Now we have a worse problem. It is a city problem so the taxpayers are on the hook. Some grants may be available. And so it goes.......
Dave, I like this very contemporary photo! The rain puddles really add interest for me.
