I've had some luck with walleyes in the gravel pits (edges of them) out from Catfish Flats, the swim beach and the old road bed near the submerged bridge. Usuallly a swedish pimple in about size 3 (1/5 oz.) in silver or gold color (sometimes with green or orange colored tape on them) tipped with the head of a fathead minnow works well. Also, airplane jigs tipped with a minnow head have great action and work well. This year, I'll be trying out the new rattlin' flyer jig by Lindy. Often times, walleyes will move up onto shallower structure during low light periods, in the 10-12 foot range. Later in the day, during high light conditions, they will often suspend over or move to deeper water, so, you have to punch a few holes to find them (this is when an underwater camera comes in handy to find them).
When working the swedish pimple, I'll actively jig to attract them and then use a less aggressive shaking or still presentation as they approach (as observed on the vex). Finally, I'll often have a set line on a slip bobber with usually a plain hook and live minnow. Between the two presentations, I try to have the fish tell me what they want. Bare in mind, I do much better on the eyes during the spring, summer and fall during the open water periods. However, they can be caught for those who take the time and have the persistence to do so. Well, I hope that this was of some help, take care and best of luck!
P.S. - Nathan Zelinsky, aka TLO, is the right guy to ask about eyes at Chatfield, as he successfully guides there (not the easiest thing to do for sure). The techniques that I use are the ones that I grew up using in MN and am still learning how to adapt them to reservoir fishing. If anyone could give you some solid technique and locational advise, it would be him. Maybe he'll put in his 2 cents worth which for guys like us, can be priceless.
