In today’s digital age, Dam Owners and Engineers knowing the location of dam related impacts both upstream and downstream is critical.  Unfortunately, the majority of impact data for DCR SWC’s 104 flood control dams are in paper or limited electronic format portraying impacts as a “screen shot in time.” In an effort to provide current impact inventories for digital use, DCR SWC has begun to modernize the data by integrating these “screen shot in time” impacts into ArcGIS online.  This presentation will explore DCR SWC’s process, showcase the output data capabilities/benefits in ArcGIS online, and evaluate the pros/cons of this modernization though lessons learned.
