Potter Water and others interested in fishing Lake Powell:
Check out Wayneswords.com, where the fisheries manager for the lake posts all kinds of good information. They actively want people to catch lots of stripers to help control the fish population in the lake.
There are different places and techniques to use, but one that's pretty easy is to go out in the deeper parts of the lake during the day and search with a fish finder to see groups of fish hanging out about 60 feet down. I use a depth indicating reel to drop a lure down that far for jigging, but there are other ways. It seems like even in the middle of the day when they might not be actively feeding, I can annoy them enough to bite...
Another way is to watch for a striper boil on the surface where the fish are herding the bait for a feeding frenzy. You can throw anything in there and they'll bite.
I also have good luck paddling around in my kayak trolling lures behind.
I'm no expert, but I find it fairly easy to catch fish at Lake Powell using basic lures like Kastmasters and Rapalas, among others.
I think Jody will be there this year, and he knows more about this than I. Maybe he'll chime in with some additions or corrections to my ramblings here.
One other thing, I would strongly recommend putting the new invisible Fluorocarbon line on your reel. I've found it makes a real difference. The hybrid Fluorocarbon coated line is less expensive than the pure stuff and it works great.
I've caught stripers, largemouth and smallmouth bass, panfish and catfish there. By the way, I need someone to teach me how to deal with catfish after they're caught. I haven't learned that part yet.
