Locations are the intersection of the high resolution NHD stream line and the visual inspection of the dam on the current Ortho imagery for Indiana. This data set contains only state-regulated dams and lake control structures listed in the DOW Unity Database. The state regulated dams were filtered from the database by using the State_Regulated attribute field by choosing = Y.
