Due to an introduction of forage fish, namely emerald and spot-tail shiners, Boysen Reservoir's walleye population grew by leaps and bounds in the 1990s. Now the reservoir, near Shoshone, produces historic-best catch rates, mostly comprised of 16-to 17-inch fish. However, four- to six-pounders are not uncommon. Wyoming's state-record walleye, 17.5 pounds, was taken here in 1997. During March and April, after the ice breaks free from the north end of the lake, look for walleyes pursuing shiners near shore and around submerged islands in three to five feet of water. An eighth- or quarter-ounce Rapala glow-in-the-dark jig, tipped with a white or black Twister Tail and a live minnow or half a night crawler is a top lure. Fish those jigs with a super-slow motion and use soft, ultralight rods in the six- or seven-foot range to detect subtle strikes. When a fish takes, feed it line, then set the hook. The Tough Creek area on the east side of the reservoir is noted as a top early-season producer. The spillway pool in the Wind River, below Boysen Dam, also holds walleyes to 10 pounds.
