Hi fishman, and welcome to Crappie.com and The Pa boards. I live near Shenango and can tell you that Mahaney and Golden Run are still closed to launch, but the others are open. I would use the main launch at the campgrounds. The water earlier in the week was still about 7 feet above summer fill. But it should be further down now. The upper launch, I think you are referring to is Parkers Landing? It is open again. I haven't been on the lake for a bit, but two friends are fishing the lake today, as they called me for advice on where to fish. I hope they do good. The fish should be moving towards shore with this cooling off, so try going shallower, like in the spring.
We are starting a crappie club, and maybe you would be interested in coming to our meeting on October 10th, at 2 pm on Lake Arthur. Many of us will be fishing the morning. When you click on the Pa boards look up to the top and you will find the link for Keystone Crappie Association. This will be our second meeting, and all input and ideas to make it the best club it can be are appreciated. Keith
