20231003 12555400 1.0 TRUE Navigability Determinations (Older data) This layer shows navigability determinations that have been conducted in the field by DNR Staff. This is not a complete data set and only includes determinations that have been mapped in the Northeast Region generally prior to 2008. In addition, this is not a complete listing of all navigable waterways. If the waterway does not show a designation then it means that it has not been reviewed by DNR field staff or the determination has not been added to this layer of information.
