The East Twin River is located in Manitowoc County. You can get on it in the town of Mishicot. I fish it exclusively during the Salmon run. It is not a nuthouse like Shoto either, although it is getting more crowded every year. There is a little more room to breath, but get there early and move downstream. I usually will keep an update on the run going in my logs, so if your wondering how the run is going here, just look there.
Here is me and Brandon at the river in 1999, and my cousin Jeff with one from about a week later.
