Jordanelle Reservoir stands as Utah's premier alpine swimming destination, offering pristine waters nestled in the Wasatch Mountains near Park City. This spectacular 3,062-acre reservoir captivates swimmers with its breathtaking mountain scenery, surrounded by towering peaks and dense coniferous forests that create a serene wilderness escape. The water's clarity and cool mountain freshness make every swim invigorating and memorable. Jordanelle's character is defined by its remote beauty and undisturbed natural landscape, attracting visitors seeking authentic high-altitude water recreation. The reservoir's elevation of 8,000 feet provides cooler temperatures ideal for summer swimming when lower elevations become oppressively hot. Multiple coves and bays offer diverse swimming experiences from protected shallow areas to deeper open water. The surrounding terrain features scenic hiking trails, wildlife viewing opportunities, and pristine camping spots. This is not a crowded tourist trap but rather a genuine mountain retreat. Practical tip: Arrive early morning to secure parking and experience calm water conditions before afternoon winds develop. Second tip: Bring extra layers as mountain weather changes rapidly and water temperatures remain cool year-round.
About This Lake
Swimming Conditions
Jordanelle Reservoir maintains excellent water clarity with visibility often exceeding 40 feet, allowing swimmers to see the rocky lake bottom. Summer water temperatures range from 55-65 degrees Fahrenheit, requiring acclimation but manageable for most swimmers with proper preparation. The reservoir reaches depths of over 300 feet in main basin areas, though swimming zones typically average 20-50 feet. Best swimming spots include the designated swim beach area near Jordanelle Dam and the protected coves along the east shore. Water currents are minimal except near dam spillways, which swimmers should avoid. The lake experiences occasional afternoon winds creating modest surface chop.
