Winter is a great time to catch big Mackinaw on Lake Tahoe. For those who can brave the cold (most guides have heaters on their boats, though), Tahoe is delivering excellent days, with double-digit monsters not uncommon. The southwest area is producing the best at around 150 feet, trolling live minnows. Shore casters are seeing very good rainbow trout action from the west shore, casting spinners or live nightcrawlers off the rocks
