Is a fishing licenses needed?

Davidtblair726: I sit on a private park board. Not for profit. The park is 80 acres with a 5½ acre pond. There is a field ditch that runs into the pond from the east. We are being told by the local CO's that we must have a indiana fishing license yo fish on our pond. They say that that ditch is a state waterway. I disagree. It is only approximately 6500 feet long from our pond out to the field where it starts. This is a run off ditch. Our pond technically is a retaining pond. Google earth may help. Frank Merry Park is the name. Address is: 18505 N. CR. 550 East. Dunkirk, IN. 47336 There are no other state waters that feed into this ditch. It is dry in July with only pockets of water. We are asking who could actually clarify this for us and explain. We are all for supporting the DNR but this seems wrong. Please help.
