Jimmy Carter created Becharof National Monument by presidential proclamation on December 1, 1978.
 The refuge was established on December 2, 1980 by the Alaska National Interest Land Conservation Act (ANILCA).
In 1983, the Fish and Wildlife Service undertook the responsibility to manage the Becharof Refuge, along with the Ugashik and Chignik units of the Alaska Peninsula National Wildlife Refuge.

In 1989 the park areas was heavily affected by the Exxon Valdez Oil Spill which devastated the Alaska Peninsula.
Puale Bay was the most heavily oiled bay outside of Prince William Sound.

In an effort to determine species presence, distribution, habitat use, and migratory patterns, extensive land bird studies were conducted from 1995 through 1998 at various locations around Becharof Lake.
Biologists continued  the monitoring work in the park 2001 through 2003 using the same methods, paying notable attention to seabird activity, along with caribou and Alaskan moose populations.
The refuge is affiliated with the Alaska Fish and Wildlife Cooperative Research Unit at the University of Alaska Fairbanks to conduct research into the drainage basin east of the Ugashik Lakes on the Alaska Peninsula to monitor moose activity.
