Johnson Lake State Recreation Area

🏆🏆🏆🏆 Central NE Playground — 2,064-acre lake in central Nebraska — one of the most popular boating and water-skiing lakes in the state

Johnson Lake State Recreation Area centers around a 2,064-acre lake in Dawson and Gosper counties — one of the busiest boating and water-skiing lakes in Nebraska. The lake was created as part of the Tri-County water diversion system — an engineering marvel that channels water from the Platte River through a 75-mile canal system to irrigate the central Nebraska plains. Johnson Lake is the holding reservoir for this system. The warm, shallow waters make it perfect for water sports — and it’s one of the few lakes in Nebraska where you can reliably water ski.
