Not sure where you are located, but if you have had the rains and floods like we have in my area, that mess may not have been there long enough to attract fish. It may have came in with high water, and next time may wash its way further back or out of the creek. It doesn't look like its been under the water too long, by the way the wood looks. If you had the in one of your local lakes, I think you would have a honey hole!!!
