I just found this article. We have had an unusual amount of rain in the Texas panhandle. Years ago we had a similar summer. Water stood for weeks on areas that had not seem water in years. We found these little shrimp like creatures. My Dad was the only person that could put a name to them. He called them Prairie Shrimp. We tried keeping some in an aquarium and they did not survive. I know in my heart there are probably prairie shrimp in some of the standing water we have now!
