The Prairie Creek Fish Hatchery near Orick, Humboldt County, California was one of the first small local fish hatcheries developed to improve the area’s sport and commercial fishing, and is one of only three remaining hatcheries built in California from 1871 to 1946.〔(National Park Service Cultural History Archive )〕 ==History== During a survey of north coast streams in 1927, coast cutthroat trout eggs were discovered on Lost Man Creek above the confluence with Prairie Creek. About a year later, traps and a temporary hatchery were built. By the spring of 1928, they had 30 troughs for the 208,000 Coho salmon and 1,400,000 steelhead eggs collected. The constant stream of fresh water needed was delivered through 12-inch flume that was nearly 2,500 feet long from behind a dam on Lost Man Creek.〔 〕 The early success of the temporary hatchery resulted in the continuation of the hatchery experiment during the early 1930s and hatchery steelhead, cutthroat trout, Coho salmon, and King salmon, were released to the wild. The site of the temporary hatchery was abandoned and the present hatchery was completely rebuilt in 1936 on approximately the same footprint as the 62-acre historic district with the five buildings and seven contributing structures recognized today: the hatchery, superintendent's house, assistant's house, sidewalks, garage shop, shed, pipeline stream crossing, and four of the round outdoor water tanks. The fifth tank was added later.〔 Several buildings were reworked and removed over the time of operation and the dam and reservoir were removed in 1989.〔 The hatchery continued production of trout and salmon during the 1940s, but as the water supply deteriorated as mechanized logging increased following World War II. Humboldt County began operating the hatchery in 1957.〔 The property was conveyed to Humboldt County by the California State Assembly on 15 September 1961 and continued operation until 31 October 1992.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Prairie Creek Fish Hatchery」の詳細全文を読む スポンサード リンク
