Have you seen that thread back posted back in February "tips on walleye"? I've not fished Cherry Creek, (other lakes are closer to me) everyone has been saying there are lots of shad, so the walleye are fat, happy, and hard to catch.
Close by I like Chatfield, Lonetree, even Union. My favorites in Colorado are Bonny, then Pueblo. I fish Glendo (3 hours north) at least once a year. I read an article recently though that Glendo walleye catch rate is going down year to year and the average fish size is also going down. (I didn't really put that together but I haven't done as well as I did in the mid 90's) Maybe it has been the drought which has affected many of the plains reserviors. This year I think I will try Sterling!
Many of the people on this board are much more adept at catching Walleye than I am. Some of the guys are fishing 200 plus days per year.
I love Walleye; its just, so many species, so many lakes, so little time.
