I for 25+ years rented a stall at Beaver Creek Dock on Feb 15th to start fishing for the whites. They stage down at Snap Holler, 39mm & Cedar Creek. Depending on the water temp & rains they slowly move up the lake into Beaver Creek, Swan & on up to the dam. Usually by the end of April it was over. Towards the late 80's each year we caught fewer & fewer. I have heard they have made a come back but am almost too old to try again.
Fun times - 1/8 oz chartruse Bass Napper jigs.
Good luck.
