Somewhere in the depth of Lake Powell is a striperful of cash. Several striped bass released into the lake this year have been tagged, and one of those fish is marked for a million-dollar prize for the angler who catches it. You can register for the contest (for free) at area marinas. However, you won't find Lake Powell's striped bass at the surface, boiling on shad, during May. Instead, schools of stripers suspend 10 to 60 feet under the surface over deep water. A wide variety of crankbaits, including ThunderSticks and #7 Shad Raps, draw strikes when trolled in the bays, such as Bullfrog and Good Hope. "The key is to locate fish with a graph, then troll between four and five miles an hour," says Tom Pettingill, a fisheries manager for Utah Division of Wildlife Resource. "You've got to really draw a strike with lure action, but most guys troll too slowly." On a good day, anglers can expect to land 30 or 40 striped bass ranging from 14 to 20 inches, with the occasional 30-inch striper showing up. Lake Powell has no daily bag or size limits on its striped bass. Contact: Utah Division of Wildlife Resources (P.O. Box 146301, Salt Lake City, UT 84114-63014; 801-538-4700).
