of Boysen Reservoir
Asmus Boysen, the man for
whom Boysen Reservoir, Boysen peak, and Boysen State Park were named was
born in Copenhagen, Denmark around 1868. As a youngster, he worked his
passage to America where he settled in Illinois. In 1889 he married Anna
Leet; they had nine children of which four survived: a son Allen and
three daughters Helena, Marie and Darlene. They later moved to Iowa.
While on a mining exploration trip to Wyoming around the turn of the
century Boysen and his party visited the Wind River Canyon. Boysen
visioned a dam that could furnish electrical power to the surrounding
mines. The water could be used for irrigation. On July 1, 1899 he
secured a grazing lease for 78,000 acres from the Shoshone and Arapaho
Indians. On March 3, 1905 he exchanged his lease to clear title of 640
acres at the mouth of the Wind River Canyon where he built his dam in
1908. It was estimated it would cost $160,000 to build. It ended up
costing $2,000,000. It was unique in that the 710 K W power plant
operated until 1925 when the floods filled up the turbines with silt and
when the reservoir threatened to flood the railroad, part of the dam was
removed. The rest of the dam was removed in 1948. Part of the original
dam can be seen on the cliff wall adjacent to the tunnels at the north
end of the Lower Wind River Canyon.
Where is Boysen State
Park? It is located near the center of the state 100 miles west of
Casper. Access to park facilities are both on highway US 20 on the east
side of the reservoir and US 26 for the south and west side of the
reservoir. The park is located at the south end of the wind river Canyon
and covers 40,000 acres. Most of the facilities are around the lake but
two campgrounds are below the dam along the Wind River. The majority of
the park is surrounded by sagebrush covered hills. The elevation is
about 4,800 feet. The area is relatively dry. The 19,000 acre reservoir
offers excellent recreation opportunities. Boysen reservoir holds the
state record for walleye at 17 lbs. 6 3/4 oz. It offers excellent ice
fishing in the winter. Many type of water foul and wildlife may be
viewed in the area. Groceries, bait, fuel for boats, campgrounds with
some hookups, and fishing licenses are available at the marina at the
north end of the reservoir. Access to park facilities are on both
Highway 20 on the east side of the reservoir and on Highway 26 on the
Boysen State Park has
eleven campgrounds of which nine of them are around the lake. The other
two are in the canyon below the dam along the river. There are over two
hundred sites with tables and grills. Most of the sites are pull through
and will accommodate large R.V's and trailers. The two campgrounds along
the river have the most shade trees and level campsites.
