About Walgren Lake

Walgren Lake State Recreation Area in Sheridan County sits in the Sandhills of northwestern Nebraska โ€” home to the legendary “Walgren Lake Monster,” a creature from Pawnee and pioneer folklore said to inhabit the lake. Whether the monster is real or not, the lake offers peaceful fishing and camping in one of the most remote parts of the state.

Things to Do

Fishing for bass, catfish, and bluegill, camping, keeping an eye out for the Walgren Lake Monster (Nebraska’s Loch Ness), and stargazing under the extraordinarily dark Sandhills night skies.

About Walgren Lake

Walgren Lake State Recreation Area in Sheridan County provides fishing on a 50-acre lake in the Pine Ridge region of northwestern Nebraska โ€” and harbors one of the Great Plains’ great legends. Originally called Alkali Lake, the lake has been the subject of “monster” sightings since the early 1920s, when local ranchers reported a 40-foot creature with a horn-like appendage. The Nebraska legislature even passed a resolution acknowledging the legend. The lake sits beneath the dramatic Pine Ridge escarpment.

Things to Do

Fishing for largemouth bass and bluegill, camping, monster-hunting (watch the water!), exploring the Pine Ridge escarpment, and visiting nearby Chadron State Park โ€” Nebraska’s first state park (1921).

Insider Tips

Monster legend: Walgren Lake has its own monster legend โ€” “Ol’ Giganticus,” a serpent-like creature reportedly spotted in the 1920s. Pro tip: Whether or not you believe in lake monsters, Walgren is a peaceful Sandhills-edge lake with good fishing. Toadstool Geologic Park: The nearby Toadstool Geologic Park features badlands landscapes with mushroom-shaped rock formations โ€” free to visit and eerily beautiful.

Best Time to Visit

Summer: Fishing and camping. Spring: Crappie spawn. Fall: Best Toadstool hiking โ€” cool and clear. Year-round: The lake is pleasant anytime.
