40-acre lake in Frontenac County, Ontario. The lake tops out around 16 ft. The depth data here comes from the Ontario MNRF survey of 1968, a decades-old survey (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 41 acres wrapped in 1.7 miles of bank. A middling shoreline index (1.9) gives it some bays to work without being a maze. Roughly 49% of the water is 15 ft or less, the band where the food chain lives. The basin spans about 0.6 mi end to end and 0.2 mi across at its widest. Frontenac County claims this one. Summit Lake sits 1 mi east — the closest neighbouring chart.
Spring largemouth bass on Crib Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 5 to 16 ft. The chart's best answer is Main-lake point — point, 10 ft, prime for fall. Prime time lands in early morning and the evening. The summer box starts with a texas-rigged 10" worm or a deep-diving crankbait.

|---|---|---|---|---|
| Spring | 2 to 10 ft | dawn & dusk | Main-lake point (10 ft) | Spinnerbait, Chatterbait |
