Description: This dataset was created from the 2014 DEM dataset with 1ft accuracy. First contours were created from the DEM. Then the 800ft. (the height of the dam) high watermark was extracted and a high watermark polygon was created. A 3ft generalization was applied to increase drawing time. Then a visual inspection was done against the 2014 imagery to verify the polygon still followed the high watermark. A buffer of .75 of a mile and 1 mile where created for each of the zones. A "doughnut " polygon was created to easily shade and view each zone on maps.
