Depending on time of year you will be there, fishing from shore can be decent to good. It really depends on where you will be. The lake is of course very large and there is only limited shore access without a boat. Fishing lake Powell is much better by boat. You can bait fish with anchovies and catch stripers and catfish in some areas around the dam and marina. The bullfrog area and halls marina areas have some shore access where you might catch some fish. You may be able to catch some smallmouth or largemouth bass with jigs and other bass lures if you can access some rocky shorelines when bass are in the shallows. Usually it is best late April, may June etc.
