27-acre lake in Sudbury District, Ontario. The lake tops out around 42 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. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 27 acres wrapped in 1.4 miles of bank. With a 1.9 development index there's bank structure worth casting at, in moderation. About 62% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. End to end it runs roughly 0.6 mi. Sudbury District claims this one. Pomfrey Lake sits 1 mi northeast — the closest neighbouring chart.
Spring brook trout on Tenho 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.
