I just started fishing again and not having much luck. I'm on Stanley Draper Lake in OKC that was drained and renovated for a few years. I did the research and found they had put some underwater pens and cages in before filling it. I hit those areas and see fish jumping here and there but not biting. I also see schools and schools of minnows everywhere in about 3ft of water. Question is, is there fish where there is that many schools of food and are they going to both biting my hook?

Competition with real forage can be a challenge that needs to be overcome. More often though, signs of forage species is a benefit by helping you identify productive spots. Look for ambush points near where you see bait fish. This could be a weedline, wood, rock, depth change etc.  Fish various baits that mimic the size, profile and maybe color of the bait (match the hatch). Of course, all this is predicated on the idea that the lake has been restocked and populations are fishable.

Thanks for the info. I'm heading out to try again in a short. Read that Wildlife Conservation stocked it with 80k 1.5in largemouth last year when they started filling it back up. Waterlines and tree lines have been a challenge since it's now fuller than it ever was and there was quite a bit of tree growth while drained for 3yrs. I've been using satallite images from past to get my bearings.

You've got the right idea, but I'd look for better water until this one recovers a  little more. A fingerling hasn't grown enough in one year to be worth pursuing. There is a fairly new pond near me that I go to occasionally but fish it with an ultra light and pick up 8" ers here and there among the sunnies. This one has a few breeders to though. I don't know how long it will take those to mature in your lake's climate, but your DEC should be able to tell you.
