50-acre lake near Dewey County. The lake tops out around 25 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Eagle Butte Lake runs 38 acres with 1.8 miles of edge. Index 2 on the shoreline: a few honest points and pockets, nothing labyrinthine.
