12-acre lake in Algoma District, Ontario. The lake tops out around 31 ft. Depth here is modeled from the true shoreline and max depth rather than surveyed; use it to plan, not to navigate. What follows comes from the same scoring engine that paints the spots above.
Rowat L. 18 maps at 11 acres behind 0.6 miles of shoreline. At index 1.2 the outline is almost a bowl — read the depth changes, not the shoreline. Littoral water — the productive band under ~15 ft — makes up 40% of this chart, as modeled. Algoma District claims this one. Its nearest charted neighbour, Rowat L. 15, is 1 mi to the northwest.
Spring brook trout on Rowat L. 18 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 Deep basin first on the milk run — a deep basin near 26 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.
