Low, flat cloud sitting over the water, with a stiffish breeze from the W and the barometer holding steady. Fish at South Boundary Lake should hold close to inflow corners and shaded margins. Plan around the stretch from morning through afternoon. Keep moving until you find them. The pre-winter feed makes autumn days generous.

South Boundary Lake lies in Hastings County, in Ontario. The country round it is rolling bush from end to end. Surface area is around 22 hectares, which gives you real water without needing a boat. With about 3.0 km of edge, you can try several depths in one session. The town to know is Bancroft, 5.2 km out. United Townships of Dysart, Dudley, Harcourt, Guilford, Harburn, Bruton, Havelock, Eyre and Clyde follows at 47 km, then Haliburton Village at 53 km. This one is safely inside the county line.
Depth is not on record here, which means reading the ground instead. On a natural lake the weed line and the shelf beyond it do the work. A soft bed grows weed late into autumn, which keeps fish shallow. Across Hastings County, recorded fish include rock bass, smallmouth bass, pumpkinseed and yellow perch. These are county-wide records, so not all of them will be in this water. On South Boundary Lake the first feature you find is usually worth a session.
Average temperature peaks around 18°C in July and bottoms out near -12°C in January. The middle months are generous; the ends are demanding. Expect a solid lid for months and a thaw around late April. Climate averages put the opening at about late April and the closing near late November. Right after break-up, and again as the nights sharpen, is when to go. Time your trip to South Boundary Lake by conditions rather than dates.
Our records carry no access rule either way. It formed naturally, so levels move with rainfall rather than with a gate. No car park, ramp or path is recorded within easy reach of the shore. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Check whether a boat is allowed before you tow one. Rules for boats are stricter than rules for the bank in many places. For a change of water, Grace Lake is 1.3 km distant. Nothing here settles the position at South Boundary Lake for certain.
