[3] After fitting out at General Engineering and Drydock Company, in Alameda, California, and shakedown out of San Diego, through 28 April, Pocatello was assigned to Commander, Western Sea Frontier, and directed to commence weather station operations out of Seattle, Washington.

He applied for a commission in the US Navy but was turned down; even though he was teaching seamanship to Naval Reserve OCS candidate at the time.

Pocatello alternated on station with the Coast Guard cutter Haida (WPG-45), and had completed a dozen patrols by the war's end.

Scheduled for disposal, she shifted to Charleston, South Carolina, arriving there on 6 April 1946, and decommissioning there on 2 May.

Pocatello was subsequently sold at Charleston, in September 1947, to J. C. Berkwit and Company of New York City.
