Idaho Fish and Game will be stocking the Big Lost River near the city of Arco the week of June 28 with 3,000 rainbow trout. According to Fish and Game records this will be the first time fish have been stocked this close to Arco since the 1980’s.

“Three good water years in a row have allowed us to place these fish close to town,” says Regional Fisheries Manager Brett High. “I hope anglers will take full advantage of this opportunity and get out fishing as often as they can.”
