Bigstorm,
Some things are better left unsaid… I will say this however,I personally know a handful of guys that have landed many walleyes in the 12 to 14 plus pound range that have been caught after dark. Yes, I said many. Most were released and a couple are on the wall. There is no way to shorten the learning curve. You better be prepared to pay your dues and even then giants will never come easy. Thank goodness. I have caught many after dark here but I am still in search of a 14 plus! I believe there are some absolutely giant walleyes available in certain areas of Rainy Lake right now. Tough to come up for a couple days and put your baits in the right place, at the right time, during the right weather, with the right light, with the right colors, etc…and catch monster walleyes. Sorry, rambling… To answer the question; Yes, you can catch walleyes after dark on Rainy Lake.
Just my 2 pennies.
