188-acre lake in Bruce County, Ontario. The lake tops out around 3 ft. What you see is a modeled chart: the shoreline is real, the max depth is published, and the contours between are estimated. Plan with it; don't navigate by it. Below is the species-by-species picture, pulled from the same data the map uses.
Traced from the shoreline, Lower Andrew Lake runs 201 acres with 8.2 miles of edge, broken up by 6 islands. With a shoreline index of 4.1, this water is all arms and coves — edge habitat well beyond its acreage. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. Call it 1.6 mi long by 0.5 mi wide at the broadest reach. You'll find it in Bruce County. The nearest mapped water is Emmett Lake, 1 mi to the northwest.
Spring yellow perch on Lower Andrew Lake hold shallow, usually 1 to 3 ft. Depth-wise the year is flat: 1 to 3 ft in summer, 1 to 3 ft once it turns cold. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
