How did Sepa Lake get its name?
Not that long ago, Sepa Lake was called Separation Lake. One of the first initiatives of Brock Bros. in 1969 was to dredge a canal between 108 Lake and Separation Lake. They then abbreviated to the more accurate name of Sepa Lake. Water levels increased and there was good boating between the lakes for many years.
There are 1922 survey maps (by Archibald, Galloway) which show both lakes with no waterway between the two lakes. Apparently, even in the 1960s, Sepa Lake was much smaller and was surrounded with fields that were cut for hay.
