Lost Man Creek Dam was a gravity dam used by the Prairie Creek Fish Hatchery in Humboldt County, California from 1936 to 1955.[1]
Location and description
The Lost Man Creek Dam was located inside the Redwood National and State Parks, in Humboldt County, California. It was positioned 0.8 miles (1.3 km) upstream from the confluence of Lost Man Creek with Prairie Creek and was 24 feet (7.3 m) in length with a width of 75 feet (23 m). The dam extended back southwards 100 feet (30 m).[1]
History
Due to

In the mid-forties, extensive logging was conducted above the watershed, which minimized water flow. This contributed to extensive sediment build up creating a barrier for the chinook salmon's migration. By 1955, the hatchery required extensive repairs, so operations were largely discontinued and production was replaced by the Cedar Creek Experimental Station.[3]
On September 15, 1961, the property was given to Humboldt County, at no cost, by order of the California State Assembly:[3]
"The property was transferred without cost to be used only as a fish hatchery for the following reasons: "The Legislature finds that there is an urgent need that all available facilities are used to produce fish for the citizens of this State and that use of this property by the County of Humboldt is a state public purpose since it will permit the continued operation of a fish hatchery which would otherwise be discontinued for economic reasons"
— California State Assembly 1961
Numerous changes were made at the hatchery during the 1960s. Since the upper dam was, by this time, completely unserviceable and created a barrier for the chinook salmon's migration, it was replaced by the lower dam. The lower dam's concrete construction was completed in August 1969 and is located upstream about 100 feet from the pipeline crossing.[3]
The upper dam was removed by
The Prairie Creek Hatchery ceased operations in 1992.[4]
