Here's a link to the pier rules for all Indiana public waters:

As stated in the letter from our legal council

The Indiana Lakes Preservation Act, IC 14-26-2, provides that the natural resources and the natural scenic beauty of Indiana are a “public right” and that the public has a “vested right” in the preservation, protection, and enjoyment of all freshwater lakes in Indiana. As part of the Agreed Order, the parties agreed that while the public has a vested right in all freshwater lakes, there are certain restrictions to that right. Specifically, IC 14-15-3-17 limits the operation of a motorboat within 200 feet of the shoreline of a public freshwater lake to those activities stated in the statute.

As it has consistently enforced in the past, it is the DNR’s position that a motorboat that is moored or anchored is not in operation for the purposes of IC 14-15-3-17. As a result, the Department will continue to not take action against any individual who has moored or anchored his or her boat within 200 feet of shoreline, provided the individuals onboard have abided by all other applicable operating laws in arriving at that point. At the same time, the DNR will promptly and diligently respond to any call that advises that anchored or moored boats are preventing egress or ingress from a citizen’s property or where occupants of the moored or anchored boats are coming upon the shoreline and trespassing on private property. The DNR will also respond to complaints that the occupants of the watercraft are littering and/or violating any other applicable infraction or law. We have received communication from the Kosciusko County Sheriff’s Department, who has advised that after
reviewing the Agreed Order and applicable statutes, their interpretation of IC 14-15-3-17 will remain
unchanged and consistent with the DNR; that an individual is not prohibited from anchoring within
200 feet of the shoreline of any public freshwater lake.

I would suggest contacting DNR law enforcement if you are being harassed in anyway while fishing or hunting as it is against state law. You can contact them 24/7 at: (812) 837-9536
