My dad caught the former lake record at La Cygne. I absolutely love that lake, but during July, August, and early September it really isn't a great lake to fish. If you do however fish the cove near the hot water outlet. There are giants lurking in La Cygne....just have to know where to find them.
Oh....also take a look up the river too. I'll post pics of the former lake record...it's hanging in my office!
