Figures 9 through 14 show contour plots of the six drops after triangulation. The outer, dark contour represents the lightest coverage level of 0.5 gpc. The inner lined contour indicates one of the heaviest coverage levels, 8 gpc.

Contour plot of drop 201 (10:31 a.m., July 12, 2001). Flight direction: north to south. Aircraft elevation: 160 feet. Windspeed: 4 miles per hour. Low-flow rate: 250 gallons of water per second. Water density: 1.00 grams per cubic centimeter.
