Navionics is the only company with Talquin mapped that I know of. It is not very good. Definitely, won't help much on where to run. Stumps are not as bad as advertised, just be careful. Don't run in creeks. Especially, North of the island. Beware of the Iron Curtain and River area too. Save your tracks for safe running. Fishing will be great next week. Don't be scared to try shallow.
