lake located in
Middle Sackville,
Halifax Regional Municipality. The shoreline perimeter is 5.6 km, the mean depth is 3 m and the maximum depth is 5 m (Mandaville 2000). Springfield is a headwater lake that is fed solely by underground springs and runoff. Located in the

(Kerekes et al. 1986). The shoreline is fully developed (lined by private homes and cottages) with over 530 houses in the 500 ha watershed. Homes on streets adjacent to the lake receive municipal sewage treatment.

There is a public beach at the northwestern end of the Lake.
