1,136-acre lake in Kenora District, Ontario. The lake tops out around 10 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. What the data behind the map says about each species, season by season:
The drawn water covers 1,134 acres wrapped in 5.9 miles of bank. Its 1.2 shoreline index means few bank features; the contours below do the pattern work. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. The basin spans about 2 mi end to end and 1.4 mi across at its widest. It sits in Kenora District. If the bite dies, Wegg Lake is 4 mi to the southwest.
Spring northern pike on Fatty Lake hold shallow, usually 2 to 8 ft. They move out to 3 to 10 ft in summer and finish the year down in 3 to 10 ft. 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 and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.

|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 3 to 10 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
