97-acre lake in Thunder Bay District, Ontario. The lake tops out around 33 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Traced from the shoreline, Fitzpatrick Lake runs 97 acres with 3.3 miles of edge. With a shoreline index of 2.4, this water is all arms and coves — edge habitat well beyond its acreage. 81% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 1.4 mi with a 0.3-mi widest point. You'll find it in Thunder Bay District. For a second option, Baldwin Lake lies 1 mi south.
When the water first warms, walleye slide up into 4 to 15 ft. By summer they slide out to 10 to 33 ft, and by winter most fish are in 10 to 33 ft. If you only fish one area, make it Break off the point: a drop-off around 15 ft that scores prime in fall. In summer the feeding windows fall in the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
