Clear air and long views across the water tonight, with a working WNW breeze and pressure sitting still. Expect most activity at Upper Pass Lake around the calm side of the wind. If you pick one session, make it the evening. Cover water early, then settle where the signs are. Fish follow the bait in autumn, so find one to find the other.

Night
The Thunder Bay District entry here is Upper Pass Lake, in Ontario. The water sits 281 metres up. Roughly 18 hectares: a morning covers one end, an afternoon the other. Around 2.7 km of margin, front to back. Amethyst Harbour is the closest place, 11 km off. Thunder Bay is the closest city, 44 km away. The nearest boundary is a fair way off.
We hold no survey for this water; read the slope of the shoreline instead. The shallow end warms first and pulls fish in ahead of the rest. Look for the band where the shallows give up and the bottom falls away. Fish documented in Thunder Bay District include cisco, blackfin cisco, rainbow smelt, bloater and shortjaw cisco. These are county-wide records, so not all of them will be in this water. At Upper Pass Lake light and wind decide more than tackle does.
The year swings from about -14°C in January to roughly 17°C in July. Spring and autumn carry the fishing; summer and winter test it. Hard cover is dependable here; it goes around late April. Climate figures give an open season running late April to late November. The first weeks of open water and the last are the ones to plan for. On Upper Pass Lake that shapes the whole year.
The access position is unclear from public sources. This is a natural basin, not a dammed one. A campsite lies 1 km away for anyone staying over. A picnic area is mapped about 1.2 km away. One rod, a handful of hooks and floats, and a few small lures are enough for this water. Some banks are open only from a marked point. Night access is frequently treated as a separate matter. If the gate is shut, Pass Lake at 0.9 km is the nearest alternative. Confirm before you fish Upper Pass Lake.
