HALLOWELL, Clifford. Through the effort of Clifford Hallowell and the local Izaak Walton League, more than 50,000 bass were released in 1943 between the Mississippi River dams at Dubuque and Bellevue. The fish had been raised at hatcheries at Guttenberg and Genoa and were placed in the river by federal and state conservation officials. (1)

In 1944 Hallowell was reelected vice-president of the National Izaak Walton League of America. He was also president of the Iowa division of the league. Iowa, at the time, led the 44 states with chapters in the number of new members. The state also had the largest percentage gain. Across the nation there was an increase in membership of 55 percent while Iowa's increase amounted to 196%. (2)

An employee of INTERSTATE POWER COMPANY, Hallowell in 1951 became the first man ever elected honorary president of the Isaak Walton League of America. His election occurred after the Dubuque resident, who was serving as vice-president declined the active presidency.

Involved in league work since its organization, Hallowell became nationally known for his leadership against pollution of streams, his purchase of elk land in the west, and his work in behalf of the Upper Mississippi River Refuge which permitted free and open access to all the waters of the river from Rock Island, Illinois to Wabasha, Minnesota. He also led the Iowa division of the organization to leadership among other state divisions in 1951 with a margin of 5,000 members.

A past national membership director and national vice-president, Hallowell began service in Iowa fighting pollution of the Cedar River at hearing in Des Moines. As a result, the river was cleared of industrial wastes. Later anti-pollution laws in Iowa were thought to be directly related to the early "clear streams" campaign.

Hallowell privately purchased a large parcel of land near Jackson Hole, Wyoming to save an estimated 8,000 elk from starvation. The land was paid for by the Isaak Walton League and donated to the United States.

Hallowell led the campaign that led to an agreement between officials in Iowa and Wisconsin that residents of either state with a resident fishing license could fish in the MISSISSIPPI RIVER anywhere between the tracks of the Milwaukee and Burlington railroads. (3) This opened fishing in the popular O'LEARY'S LAKE.
