About Our Site - Seminoe State Park
The Seminoe Mountains surrounding Seminoe State Park were once the site for gold prospecting during the late 1800s. The name “Seminoe” is commonly assumed to come from the Seminole tribe, but is an Americanized spelling of the French name Cimineau. Basil Cimineau Lajeunesse was a French trapper in the area in the 1800s. Seminoe State Park, located on the northwest side of the reservoir, was established in 1965 through an agreement between the U.S. Bureau of Reclamation and the Wyoming Recreation Commission (predecessor to Wyoming State Parks and Historic Sites).
Seminoe State Park Announces Water System Upgrades and Service Interruptions
SINCLAIR, Wyo. — Aug. 25, 2026 — Wyoming State Parks is advising visitors to Seminoe State Park to plan for intermittent water system interruptions through the remainder of the camping season as upgrades to the park’s water system are completed.
Campers are encouraged to arrive with their RV or camper water tanks filled, as water availability within the park will be limited at times during construction.
The park’s dump station will remain open; however, construction activity may occasionally affect access or timing of use. Visitors are encouraged to plan accordingly and allow for potential delays.
Wyoming State Parks appreciates visitors’ patience and understanding as these improvements are completed.
