🏆 Sandhills Lake — 5,124-acre reservoir in the heart of Nebraska’s Sandhills — one of the best walleye fisheries in the state
Calamus Reservoir State Recreation Area centers around a 5,124-acre reservoir in the heart of Nebraska’s Sandhills — one of the most unique landscapes in North America. The Nebraska Sandhills are the largest dune system in the Western Hemisphere — covering 19,300 square miles (about one-quarter of Nebraska!). These grass-stabilized dunes sit atop the massive Ogallala Aquifer, which provides water for much of the Great Plains. Calamus Reservoir is one of the top walleye fisheries in Nebraska — the clear water also supports excellent bass and northern pike fishing.
