Lakes in the Mammoth Lakes Basin

The basin is home to several distinct lakes, each offering a slightly different fishing experience.

Twin Lakes

The lowest lakes in the basin, actually a group of three, are the first to open each spring and the last to close, making them a reliable option early and late in the season.

Lake Mary

The largest lake in the basin and the only one that allows motorboats, making it ideal for trolling and covering more water. It’s also a great place to spot bald eagles.

Lake Mamie

A smaller, quieter lake just downstream from Lake Mary, offering a more relaxed fishing experience.

Lake George

The highest drive-to lake in the basin, Lake George is known for cool water, clear conditions, and strong trout populations.

Horseshoe Lake is also located in the basin but is not considered fishable.

Together, these lakes make the area one of the most diverse collections of easily accessible fishing spots in the region.

Getting There

Main Street (State Highway 203) in Mammoth Lakes connects to Lake Mary Road, which leads directly into the Mammoth Lakes Basin.

The first lake you’ll reach is Twin Lakes, located about 2.5 miles from the center of town.

For anglers exploring multiple areas, the basin is often part of a broader fishing in Mammoth Lakes experience.

Best Time to Fish the Mammoth Lakes Basin

Fishing conditions in the basin remain consistent throughout the general season, with a few key patterns:

Spring–Summer: most consistent fishing and full access to all lakes
Early mornings and evenings: best activity levels
Fall: fewer crowds and active trout

Because each lake varies in size, depth, and fishing pressure, adjusting your approach can make a noticeable difference.

Fishing Tips for the Mammoth Lakes Basin

The basin is regularly stocked and home to rainbow, brown, and brook trout, with Twin Lakes also holding native tui chubs.

Bait fishing with PowerBait or night crawlers is effective
Spin fishing with lures like Thomas Buoyants and Rapalas works well
Fly anglers often use Woolly Buggers with nymphs

Because conditions vary between lakes, checking with local tackle shops can help dial in what’s working best.

General season regulations apply, with fishing open from the last Saturday in April through November 15.

Know Before You Go

The Mammoth Lakes Basin sits at elevations above 8,000 feet, so weather conditions can change quickly.

Be prepared with proper clothing layers, sun protection, and plenty of hydration. The area is also home to a variety of wildlife—never approach, feed, or provoke animals.

If heading into the backcountry, always let someone know your plans and expected return time.

Why Fish the Mammoth Lakes Basin

The Mammoth Lakes Basin offers a rare combination of accessibility, variety, and consistent fishing.

With multiple lakes in one area, anglers can explore different waters, techniques, and conditions without traveling far. Whether you’re fishing for a few hours or spending the entire day on the water, the basin provides a flexible and rewarding fishing experience.

Camping and Lodging

There are a wide variety of camping options throughout the Mammoth Lakes Basin, ranging from tent sites to motorhome accommodations.

Lodges and cabin rentals are available at Twin Lakes, Lake Mary, and Lake Mamie. The area is very popular during the summer, especially on weekends, so reservations are recommended.

The basin’s proximity to town also makes it easy to combine camping with additional lodging options in Mammoth Lakes.
