25-acre lake in Algoma District, Ontario. The lake tops out around 60 ft. The depth data here comes from the Ontario MNRF survey of 2010 (a transect sounding survey). What the data behind the map says about each species, season by season:
Mud Lake maps at 25 acres behind 1.3 miles of shoreline. With a 1.8 development index there's bank structure worth casting at, in moderation. About 34% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. End to end it runs roughly 0.5 mi, about 0.2 mi across. Algoma District claims this one. If the bite dies, Smokey Blue Lake is 1 mi to the northwest.
Spring brook trout on Mud Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 19 ft that grades prime for summer. The feeding windows run early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Secondary point (3 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (19 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Secondary point (3 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (19 ft) | Small jigging spoon, Tungsten jig + plastic |
