Cloud from horizon to horizon today, with steady pressure of wind from the W and pressure going nowhere. The water to cover at Span Lake is inflow corners and shaded margins. Numbers are low everywhere; the evening is the pick of them. Lower the pace and stay patient. The season of moving fish: stay mobile and watch for bait.

Ontario holds Span Lake, in Nipissing District. It sits in lake country bush country. Surface area is around 16 hectares, which gives you real water without needing a boat. The whole outline is near 2.1 km, and most of it is walkable. The closest town, Mattawa, is 27 km away. Deep River is 71 km away, with Callander at 74 km. The nearest boundary is a fair way off.
No published figure covers depth, so learn it as you fish. Still water like this holds fish on the edges rather than out in the open. A natural lake fishes on cover, and cover here means weed and timber. Nipissing District records list smallmouth bass, cisco and yellow perch among the fish reported. County records show what lives in the area; the local agency holds the water-by-water list. The shape of Span Lake rewards a slow walk along one bank.
Typical July readings run about 18°C; by January the average is down near -13°C. A hard winter is normal, and the thaw brings a strong few weeks. Count on hard cover from midwinter, and open water from late April. On the long-run averages the water opens up around late April and starts locking again about late November. June through September is the settled part of the year, with the shoulders busier for fish. On Span Lake that shapes the whole year.
Access is not recorded for this water. This is a natural basin, not a dammed one. Nothing is listed nearby for parking or launching a boat. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Parking is often the real limit rather than the bank itself. Fishing rules and camping rules are set separately here. The nearest alternative is Mart Lake, 1.8 km out. Confirm before you fish Span Lake.
