I have fished Shagbark a lot and it is amazing! Bass jumping in the boat, blue gill the size of Texas and several musky that'll give your ultra-light a shreddin', yep, an amazing little honey hole. But......it is private. And don't even think about trying it out without permission. My friends father lives on the lake and has informed me that unless you know a resident and have explicit permission the police will be called and charges of trespassing will be filed. Sorry, but it is a great spot that pretty much only older people live around and hardly ever gets fished, except by my and my buddie. And all but the one FP lake you mentioned are very, very likely private as well. Unfortunately there are a lot of these little lakes that guys like us, the WCF crew, would be very blessed to live on and be able to fish day or night, but unless we can pool up the $600k plus to buy a house on one of em we just have to pray for a nice friend to let us in once a week!
PS I would invite y'all if I could! No, really I would!!!
