Before Glendo Dam could be built on the North Platte River in Platte County, Wyoming, complicated water-rights disputes had to be settled among Wyoming, Nebraska and Colorado and the settlement approved by the U.S. Supreme Court. The process took more than a decade, and shows the difficulties of allocating water in the arid West. The earthfill dam, nearly 2,100 feet long and 190 feet high, was completed in the fall of 1957. It stores water for irrigation and recreation, controls floods, reduces sedimentation in the Guernsey reservoir downstream and produces hydropower.

Businessman, family man, territorial and state governor, U.S. Senator: Francis E. Warren succeeded in all of these roles, but he is best known for long service in the U.S. Senate on behalf of Wyoming. A Massachusetts native, Warren arrived in Cheyenne in 1868, when the city was still a mass of tents and other temporary structures, and quickly became involved in its business and politics. By around 1900 he was Wyoming’s most powerful Republican, and ran his party’s so-called Warren Machine for decades by patronage and pork-barrel politics.

Guernsey Dam on the North Platte River lies between historic Fort Laramie and Laramie peak and just a few miles from some deep, sandstone ruts on the historic Oregon Trail. The dam was completed in 1927, for hydropower and flood control. In 1934, crews from the Civilian Conservation Corps located camps near the reservoir. With design help from the National Park Service, they built the handsome stone-and-timber shelters and buildings at Guernsey State Park, in what became a showplace of state park design.
