9,000-acre flowage near Merrimac. The lake tops out around 24 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Here is how the season plays out for each species, straight from the data behind the map.
Start shallow in spring: walleye sit in 4 to 15 ft that time of year. Summer pushes them deeper, 7 to 24 ft, and winter fish settle into 7 to 24 ft.
