I would skip Lenore, or at least be prepared to change venues if it disappoints. Blue and park lks right there should have fast fishing for twelve inch planter bows, plus both have the added bonus of browns that get big enough to keep things interesting. Only bad thing is the bait plunkers lined up shoulder to shoulder along the bank.
I agree; after the recent big poaching bust on Lenore, I know that I wouldn't waste too much time there. (do a search on the site for the story)
If you are fishing this Thursday and Friday, be award that Blue and Park won't open until Sat. As TJ said, they can provide good action for catchables when they open. Rocky Ford creek, Dry Falls and Banks Lake are all good back up plans for Lenore as are the Quincy lakes.
