Winter Fishing on Lake McDonald

Lake McDonald is the largest and most popular lake at Glacier National Park. Located in the west part of the park, the lake is surrounded by mountains, stretching for about 10 mi (16 km) and offering spectacular views during any season. The best time to hike in Lake McDonald Valley is in the summer. The Glacier Park's hiking season generally runs from late May or early June to mid-September or October. In the winter, some services are limited, and roads are closed due to snow. The section of the Going-to-the-Sun Road from West Glacier to Lake McDonald Lodge, however, is open year-round.

The road runs parallel to the southern shore of Lake McDonald. The eastern shore of the lake borders the Continental Divide. Lake McDonald Valley's flora is dominated by western red cedar, spruce, fir, and hemlock. Meanwhile, the fauna includes bighorn sheep, black bears, grizzly bears, mountain goats, mule dear, and elk. The lake lies on an elevation of 3,153 feet (961 m) and was once occupied by massive glaciers.

Rainbow Rocks

Lake McDonald's waters are crystal clear since its cold temperature doesn't permit plankton or algae. So, it's easy to see millions of colorful pebbles on the bottom. These rocks were formed during different times, starting from the ice age when the lake was created by glaciers. Rocks' color depends on the amount of iron and other minerals.

Fishing

Even though Lake McDonald is not considered to be a great fishing destination, it's possible to fish here. Beautiful views will surely compensate for the poor catch, as the lake lacks sufficient nutrients to sustain a large fish population. Anglers can fish from the shore, using a hook and line.

If you want to use a boat, you'll need to obtain a boating permit.
