The regs may be a bit confusing, for they consume a few pages. And yes, to know the boundaries of when and where you can and cannot fish after dark varies from stream to stream - BUT - the regs do answer both those questions as well.
There is no fishing permitted from a half hour after sunset until a half hour before sunrise. If you want to be precise in those hours, look up the deer hunting hours, they are the same.
As to where on those waterways does that mean I can fish in those non-permitted hours? Nowhere! Can one fish on the pier? If where you want to fish on the pier is not part of the stream/river. How does one know? Do I need to look for some sign or ask the locals?
No! Where doe the stream end and the lake begin? It is that simple.
How can you tell? Look for where the shoreline meets Lake Michigan on one side of the river, then find where the shoreline meets Lake Michigan on the other side of the river, draw a line from one side to the other, you need to be one the lake side of that invisible line to fish at night.
Oh, and another tip for Salmon fishermen. A legally caught fish must be hooked IN the mouth, not in the head, not in the eye, not NEAR the mouth, but IN the mouth. You can be ticketed if a fish is kept which was hooked other than In the mouth.
Now, a question I have, have they been catching any on the pier?
I was born in Algoma, but now live in Shawano area, so I need to rely on these reports to know if they are staging outside the pier heads or not.
Peace of The Lord be with you.
