Inscription.  
In the early 1900s, Asmus Boysen, a Danish immigrant and successful businessman, dreamt to building a dam that would provide water and power to Central Wyoming. The dam was to be an engineering achievement, spanning 180 feet high and 124 feet long, with a lake 14 miles long and 2 1/2 miles wide. The power plant was unique with five turbines generating electricity to nearby mining camps and to Shoshoni and Riverton.
Boysen's dream was short-lived as a series of flash floods deposited tons of silt and sand causing the turbines to shut down. Water rose behind the silt-filled dam and threatened the nearby railroad tracks. To prevent more flooding, Boysen blasted away part of the dam. But over the years, flooding continued to damage the dam until 1948 when the Bureau of Reclamation completely removed it.

Today, silt deposits from the original dam provide the sites of both the upper and lower Wind River campgrounds.

One of the requirements to claim a homestead under the 1877 Desert Land Act was irrigation. When the first homesteaders came into the Wind River area in the 1890s, many of them made at least a token attempt to draw water from the river or its tributaries.
