- Comments:
- Lake Manitoba is the third largest lake in Manitoba and is part of a large watershed that occupies a large portion of this province and into Saskatchewan. It is part of the Interlakes Region that includes other significant lakes such as Lake Winnipeg and Lake Winnipegosis. Lake Manitoba is so large and surveys were conducted for portions of the lake only, that those of clustered locations are compiled together but more distinct parts of the lake are entered as seperate entries. See individual entries for more details. This entry compiles individual entries for Lake Manitoba into one total entry for indexing purposes.
