703-acre lake in Thunder Bay District, Ontario. The lake tops out around 26 ft. The depth data here comes from the Ontario MNRF survey of 1990 (a transect sounding survey). Here is how the season plays out for each species, straight from the data behind the map.
Eayrs Lake maps at 706 acres behind 13 miles of shoreline — 11 islands included. The 3.5 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 75% of this chart. The basin spans about 2.3 mi end to end and 1.2 mi across at its widest. It sits in Thunder Bay District. Its nearest charted neighbour, Gutteridge Lake, is 9 mi to the east.
Spring puts yellow perch in skinny water — 3 to 12 ft is the zone. Warm water sends them out to 8 to 26 ft; cold water stacks them in 8 to 26 ft. Deep basin is the standout, a deep basin at roughly 26 ft, rated prime for fall yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm covers the summer program.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (2 ft) | Small jig + curly tail, Perch-pattern micro crank |

Spring northern pike on Eayrs Lake hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 2 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.
