----------------------------Original message---------------------------- Folks: A guy who's doing research on scuba diving accidents asked me a good one. He wants to relate the number of scuba accidents in each U.S. state to the length of their coastline. We found the ocean and Great Lake shorelines, but not other lake and river shoreline lengths. Does any one know of a source for these? There are some ifs, ands and buts in this, I know (ie. you can't scuba dive in all the possible lake and river locations), but still anything yyou can point me to would be appreciated.
