Becharof Wildlife Refuge Becharof lies between Katmai National
Park and Preserve and Alaska Peninsula Refuge. The refuge is
dominated by Becharof Lake, the second largest lake in Alaska.
The lake covers one-fourth of the refuge and is surrounded by
low rolling hills, tundra wetlands, and volcanic peaks. The
salmon spawning streams attract one of the largest
concentrations of brown bear in Alaska. Some brown bear of
Becharof exhibit a unique habit of making dens on the islands of
Becharof Lake. Moose inhabit the refuge in moderate numbers and
about 10,000 caribou migrate through and winter on the refuge
seasonally. Other mammals include wolves, wolverines, river
otters, red fox and beaver. In addition, thousands of sea
mammals such as sea otters, sea lions, harbor seals and
migratory whales inhabit the shoreline. Becharof Lake and its
tributaries contribute over four million salmon annually to the
Bristol Bay fishery. Salmon, arctic char, and grayling flourish
on the refuge. Waterfowl are common in the wetland
