The U.S. Northeast is a beautiful region of mountains, forests, rivers, and lakes. Some of these lakes possess some of the most transparent water in the country and can be pretty wide. One of these lakes is Lake Winnipesaukee in New Hampshire. Just how wide is Lake Winnipesaukee?

Facts About Lake Winnipesaukee

This lake is an astounding nine miles across!

Lake Winnipesaukee is the largest lake in New Hampshire, between Belknap and Carrol counties, with a surface area of 71 square miles. It is also the sixth-largest natural lake in the United States and a locale of unrivaled beauty. The lake, nestled among the mountains and woodlands of New England, has sparkling, clear water and abundant wildlife. Its nearly 365 islands provide an exciting backdrop for swimming, fishing, and sailing.

Lake Winnipesaukee is a vast lake measuring 9 miles across at its widest point. It’s 20.8 miles long and has 365 islands accounting for 288 miles of shoreline. It is one of the largest lakes in New England.

How Long It Would Take the Average Swimmer to Swim Across Lake Winnipesaukee

Although Lake Winnipesaukee is 9 miles across at its widest point, it is littered with islands. A swimmer would have to swim 10.21 miles to navigate the path through these islands. At 2 mph, it would take an average swimmer 5 hours and 6 minutes to swim. For comparison’s sake, a marathon swim is considered to be over 6 miles. This would be a little more than the distance of Mexico’s Sumidero Canyon Swimming Marathon, which is about 9.32 miles.

The lake’s selection of salmon, trout, bass, pickerel, smelt, and bluegill provides some of the best fishing in New England. The Meredith Rotary Club also sponsors an annual fishing derby with substantial cash prizes.

There are swimming beaches, hiking trails, and biking trails ranging from 11 to 52 miles long. Ellacoya State Park in Gilford is on the lake’s southern shore.

The fun doesn’t stop in winter, either. Lake Winnipesaukee is a popular destination for ice fishing and other winter activities, such as skiing, snowmobiling, ice skating, and snowshoeing.

In addition to activities on the lake, several small towns around the waterfront provide entertainment.

Wildlife Around Lake Winnipesaukee

Large Mammals

Throughout the forests and on the mountains, many large mammals reside in the Lake Winnipesaukee region, including black bears, bobcats, coyotes, red and gray foxes, moose, and wolves. There is an abundance of smaller prey to support them.

Small Mammals

The number of small mammals throughout this region is impressive, with a diversity that includes mice, rabbits, lemmings, shrews, raccoons, skunks, opossums, porcupines, flying squirrels, otters, muskrats, beavers, and bats. There is also a resurgence in the area of fisher cats, also known as fishers, which are nocturnal hunters resembling a cross between a weasel and a cat. They were nearly extinct but are now found throughout the region.

Birds

Given the presence of such a pristine lake with abundant surrounding forest, it’s no wonder birds can be found in great numbers at Lake Winnipesaukee. Of course, there are several waterfowl and shorebirds, including loons, mallards, black-headed gulls, piping plovers, great blue herons, and snowy egrets. There are also many other interesting species, such as the golden eagle, ring-necked pheasant, ruffed grouse, eastern bluebird, ruby-crowned kinglet, hermit thrush, indigo bunting, and dark-eyed junco.

Reptiles and Amphibians

Reptiles and amphibians abound, with salamanders, mudpuppies, frogs, and turtles, as well as a variety of snakes, including timber rattlesnakes, common garter snakes, and redbelly snakes. The redbelly snake is small (under 10 inches long) with a unique coloring—black with a red underbelly. Such a boldly colored snake would appear dangerous, but that couldn’t be further from the truth: redbellies are not venomous, feeding on worms and slugs.
