Slim Lake Fishing Guide, Nipissing District, Ontario

• Overview

  Slim Lake lies in Nipissing District, in Ontario. Height above sea level is 449 metres. The water measures roughly 9 hectares, so nothing here is far from anything else.

A border sits close enough to be relevant to the paperwork.

• Where to Fish on Slim Lake

  No depth figure appears in our records, so the bank has to tell you. A soft bed grows weed late into autumn, which keeps fish shallow. Look for the band where the shallows give up and the bottom falls away. Public occurrence data for Nipissing District names smallmouth bass, cisco, yellow perch, pumpkinseed and rock bass. Records at county level tell you what is around, not what is stocked here. On Slim Lake the quiet end is the one worth the extra effort.

• Seasonal Patterns

  July runs about 18°C on average, January about -12°C. Four clear seasons, with a proper winter at one end. Once it clears, about late April, the fishing comes on quickly. Break-up near late April, freeze-up near late November: that is the shape of an average year. Fish feed hardest at the start and the close of the open season. Slim Lake runs to that rhythm year in and year out.

• Tackle & Baits

  Who may fish here is not settled in anything we hold. There is a campsite 1.2 km from the water. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Where a permit is needed, the nearest town usually sells it. Access can change hands, so last year's answer may not hold. Sly Lake sits 1.5 km off and takes the overflow. The position on Slim Lake is worth confirming on the day.
