WWD areas are something I should look into. Thanks for the advice. Other than not finding suitable pools for the fish the Dupage has only been frozen once day so far. I went out again today but no fish. I waded a new stretch of the river and found some new holes, undercut banks, and some flats. I would imagine these places will be hot once it warms up but just not right now. I'm taking my time working the river to make sure I change up flies and retrieves in efforts to be thorough. I just need to find that deep hole on the river where they are hibernating lol. Thanks for the advice.
