Note that report 226 Seymour Aquifer was scanned 100% as 150 dpi greyscale. 
The 10 color plates were scanned separately at 200 dpi, but these color pages are not missing from the main greyscale document.

Several color figures in the main document were left as greyscale to conserve network space. These pages can be scanned in color if needed.
