I don't fish just about anywhere. I fish certain spots- points, ridges, flats, feeder creek channels. Why hike all around the reservoir if you know where fish can be located when they're feeding. Locate a few spots depending on the seasonal pattern, your experiences, and what you observe in the water and do a milk run. Fish the bottom and the middle (and maybe the top too if you feel like it) each with a couple different presentations and move on to your next spot if you're the restless type. Me, I got tons of patience. I'll wait until the fish are ready to come up to their kitchen and eat my bait. Till then, I can wait. Besides, if they're biting, they're biting everywhere, and I'm in a good location anyway. Did I mention I hate hiking?
There was this one local res- well it's still there, but closed right now- where I'll fish a point all evening and catch tons of fish. One every three or four casts. When they'd stop biting a senko, I'd tie on a small jig and start catching them again. 15-20 fish in about a couple of hours, almost everyday. Sometimes they'd be on the edges, sometimes on the point itself, sometimes they wanted a fast bait, sometimes a slow one, but they'd relate to that main lake point all summer and early fall.
