Upper Mirror Lake

Upper Mirror Lake is a peaceful, little-known treasure tucked inside the McNenny State Fish Hatchery, located just northwest of Spearfish in the northern Black Hills of South Dakota. Fed by cold, clear water that supports active trout stocking operations, the lake offers anglers excellent opportunities to catch rainbow trout from dedicated fishing piers. The water is famously clear, reflecting the open skies and surrounding hillsides that give the lake its name. Because it sits within the hatchery grounds, Upper Mirror Lake sees far fewer visitors than other Black Hills fishing destinations, making it ideal for those seeking a quieter, more serene outdoor experience. Visitors have spotted bald eagles near the entrance and a variety of birds throughout the grounds. Whether you're a seasoned angler, a nature photographer, or simply looking for a tranquil escape from busier tourist areas, Upper Mirror Lake delivers a genuine Black Hills experience. It's open year-round and accessible to visitors of all ages and skill levels.
