A new addition to the web site, more than 4500 scanned lake depth maps are available for viewing and printing.
Web browsers such as Netscape Navigator or Microsoft Internet Explorer can't view these images directly. You must install additional image viewing software (Netscape plugin, ActiveX component or stand-alone application) capable of displaying TIFF Group 4 compressed images or Adobe PDF files. Listed below are some software packages that are known to support these format. (Please note that the information in the TIFF and PDF versions are EXACTLY the same.)
Which format to use? Depends. Software that displays the TIFF versions is generally more flexible and will allow users to do things like rotate and annotate the maps. Because PDF files and the Adobe PDF reader are so common, many users may find it more convenient to use the PDF files. Your mileage may vary. Both formats can be used to generate very usable maps on standard 8.5" by 11" paper. (Keep in mind that print quality is greatly affected by the image scan quality and the type of printer you're using.)
Getting the Lake Maps
To retrieve a map you may use the Lake Finder or the Recreation Compass. Links to existing maps can be found at the bottom of each lake survey report. In addition you can search for lakes by name or by county and get direct access to either the lake survey report or the lake map. Try it out here!
