Structure Thoughts - Submerged Island/Hump (year: 1973)
Don Woodruff first introduced this natural lake, topo-map example in a previous magazine article, but this little "hump" structure wasn’t on the original map. It was later added for the 1973 article rferenced here, and his comments about it (as well as mine) follow:
✅ Fish structure #4 is the classic submerged-island, a high knob or raised portion of the lake bottom.... often referred to simply as a, "hump."
Sometimes these structures are small, measuring in feet rather than in yards. For this very reason, you should check them out carefully. Many, if not most fishermen, may not even be aware of their existence.
🗯️ My thoughts: This is actually a pretty complex area, as you can see on the map.
There is a long point or bar just south of this island or hump, and this island/hump is almost an extension of it, in essence, creating a saddle between the two structures.
You also have a moderate flat to the east that ends at a deep hole (marked as 50'), and a steep drop to the west (point of arrow).
Depending on bottom composition in the area, as well as lake stage (Meso, Eutrophic, etc.), the 10 ft flat around the island could be weeded, or just sand/rubble with isolated patches of greenery. Regardless, you could make the case that the area could easily house many different species of fish, at many different times of the year - pre-spawn through cold water, and everything from largemouth, smallmouth, pike/muskie to walleye…even panfish. Well worth checking out and fishing in detail, IMHO.
