No one, including the biologists, knows why, but from the end of December through the first of April, walleyes pour through the Tygart Lake dam during high flows (four to six gates open) in large numbers. This is the only time of year this occurs, and this is the only lake in the state where it happens. Some of the most active walleye fishing is found in the first half-mile below the dam when the flow is up and three or four gates are open. The bigger fish, however, tend to move out of the tailwaters fairly quickly to take up residence below Valley Falls State Park near Hammond, about 11 miles downstream. During extremely high spring flows, the walleyes will move in toward the shore, so the good bank-fishing continues even if the water gets a bit unwieldy. Jigs tipped with minnows or three-inch white or chartreuse plastic grubs are some top walleye lures.
