MSWP Regatta Permit Search
Although I'm not into fishing tournaments, I'd rather avoid fishing when there are several or a large tournament scheduled on a lake I'm planning to fish. This site even shows some of the smaller lakes, which even a small tournament might make me have some consideration when to fish it.
So, this site may give you an idea when to avoid fishing a particular lake or it may encourage you to enter a scheduled tournament.
Hope this helps....
Thanks for the link.
