Costello Lake Fishing Guide, Timiskaming District, Ontario

• Overview

  Costello Lake stands in Timiskaming District, Ontario. It sits at 249 metres above sea level. It measures about 21 hectares, which is a comfortable size for bank fishing. There is roughly 2.5 km of shoreline here, which is a short walk end to end. Nearest town is Englehart, 24 km off. Beyond it, Kirkland Lake at 36 km and Temiskaming Shores at 54 km. This one is safely inside the county line.

• Where to Fish on Costello Lake

  No figure exists for depth, so let the water show you. Still water like this holds fish on the edges rather than out in the open. The productive water is a rod length or two out, not a hundred. Open biodiversity records for Timiskaming District list brook trout, northern pike and yellow perch. What holds for the county may not hold for this water. On Costello Lake that means starting tight and working out.

• Seasonal Patterns

  Seasonal averages run from -16°C in January up to 18°C in July. The middle months are generous; the ends are demanding. The freeze runs deep into the year, with break-up near late April. Open water usually runs from late April until about mid November. Look to early summer and the first cool weeks of autumn. On Costello Lake the same rules apply, with local timing.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. This is a natural basin, not a dammed one. No slipway, car park or made path shows up nearby in mapping, so treat access as rough. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Look for a notice board at the entrance. A polite question at the farm gate opens more banks than anything else. Kearney Lake, 1.1 km away, makes the obvious fallback. Rules at Costello Lake are worth checking on the day.
