Lake Pepin
Lake Pepin is not really a lake. It is a natural widening of the Mississippi River created where the Chippewa River delta slows the current, and it sits at the center of Pool 4, the stretch between Lock and Dam 3 at Red Wing and Lock and Dam 4 at Alma. Anglers working this water for walleye, sauger and white bass already know how much the bottom changes from wing dam to sand flat.
This Lake Pepin map from Mapping Specialists shows that structure instead of describing it.
- Shaded 3D rendering of the lake bottom, so drop-offs and channel edges read at a glance
- Boat launch locations marked around the pool
- Rock areas and aquatic vegetation identified
- Land area shown in high resolution aerial imagery rather than flat basemap color
Finishing choices at Map Shop include paper, laminated, mounted to foam core, black or walnut rails, and framed.
