every "every" does have its exception and thanks for your sanctioning use of quotation marks, O Exhalted Leader!

Thanks for the great links, tsuwm! I'm amazed you had this information at your fingertips to respond to this thread! How so? I did notice, however, that both Devil's Lake and the midwestern lake mentioned once had outlets since filled-in from disuse.
There also may be some landlocked mountain lakes of small acreage...but most of these are spring-fed and create brooks or brooklets as outlets, so they go into the watershed-flow column.
