Fish Habitat Enhancements
Iowa DNR Fisheries staff use many habitat enhancements
on Iowa waters to improve your chance of catching fish. They build some enhancements
on the dry or frozen bottom and place others
from a boat in existing water. Each habitat enhancement has its own limits
and benefits that are usually focused on a specific species, season or type
of fishing. Common enhancements are tree piles, rock reefs and mounds,
spawning attracting areas, stake beds, benched jetties, bank hides and
Where these enhancements are placed can vary widely. All
depths and locations can offer benefits to many species during some time of the
year. A site is chosen based on a many factors such as the natural
bottom contour, where fishing would be best to avoid conflicts with other
activities, siltation, behavior patterns of the desired fish species, as well
as any other concerns. Branches from brush piles are sometimes
left exposed to help anglers find these submerged
locations. Habitat structures placed in deeper water offer shelter
during summer months, and structures placed in the deepest areas can provide
excellent cover for winter panfish.
