Delegates to Wyoming’s Constitutional Convention had to work quickly in 1889 to get a constitution adopted while Congress was still in session. Still, they managed to adopt some innovative ideas, especially in water law. The biggest stumbling block to statehood, in Congressional debate the following year turned out to be whether Wyoming had enough people. It was a close call.
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.
