Rainbow Flowage is a dammed stretch of the Wisconsin River in Oneida County, and its bottom is a lot more complicated than the surface lets on. This Rainbow Flowage lake map from Map Shop renders that underwater terrain as a shaded 3D surface, so humps, breaklines and old river channel run read at a glance instead of as a stack of contour numbers.
- 3D visual representation of the lake bottom showing depth change and structure
- Boat launch locations marked around the flowage
- Rock areas and vegetation beds identified
- Land area shown in high resolution aerial imagery, so shoreline timber, roads and cabin clearings appear as they actually look from above
Northwoods fishing guides use it to plan a morning milk run before the trailer hits the landing. Cabin owners hang it over the fireplace in the great room, lake association boards mark shoreline issues on it, and bait shops keep one by the counter. Choose lamination for wet-erase notes on productive spots, or foam core mounting from Map Shop if you would rather pin them.
