When I was a kid, Salt Creek ran by our place. When the Eisenhower Expressway was built (in the 50's) They got all the topsoil for the sholders from 300 acres between us and the creek. Took about 3 to 4 fet out. Every few years that would flood to about 4-5 feet deep. They had left a small levee along the creek so the water would be trapped. 
The carp would get in there by the thousands. Two fellas my folks knew would come in with nets and sell them some place. I never knew where, but they seemed to make a pretty good buck at it. 
Hope it dries out for you real soon.                              Larry
