2017 Map of Johnson Lake

About this map

Johnson Lake anchors this Central Nebraska landscape, straddling the border between Dawson and Gosper counties. This water management system is defined by the Tri County Supply Canal and a series of smaller impoundments, including Elwood Reservoir, Knoeizer Reservoir, and Canby Reservoir. The map reveals a developed recreational and residential shoreline, particularly at Mallard Beach and North Shore, where numerous bays and points like Mallard Cove and Kilby Point articulate the lake's perimeter. To the north, the Platte River flows past Danielson Island, while the surrounding terrain is etched by drainage features such as Plum Cr. The inclusion of the Johnson Lake Airport and a dense network of local roads like Elwood Lake Dr indicates the area's role as a regional hub for water-based activity and transit.
