I just got back from the Lower Illinois River below Tenkiller Reservoir in OK. It was unusual for 3 reasons. First I have never fished for trout in the summer time it Oklahoma( crowds and heat). Second it has rained hard in the area a day before are the the river was like mud. I have never seen it as bad before, and third I caught 10 diffrent species of fish.
My buddy and I got to the river at 5:35 am and not a soul was there. the river looked awful but we were there so we started fishing. One of the first fish I caught was a 5 lb striper on a size 10 marabou jig. A few lost fish later I realised I had to change out my tippet because the striper had over stretched it ( I probably had my drag a little tight) A few people straggled in between 9& 10 am but there were very few people wherever we went on the river. We wet waded so it made the afternoon temperatures bearable.
Here is a list of fish that I caught

Rainbow trout ( lots of them) all released to feed the stripers
Striper
Sauger
Small mouth bass
Channel Cat
Fresh water Drum ( the 2 largest were a 12-13 inches)
Bluegill
Green sunfish
Crappie
Buffalo ( in the sucker family )
