Costello Lake, Ontario: Fishing Spots and Seasons

• Overview

  Costello Lake is one of the Nipissing District waters in Ontario. Height above sea level is 416 metres. With some 34 hectares of water, there is room for a boat but no need of one. The bank runs about 3.7 km all the way round, so one visit can cover most of it. Haliburton Village follows at 63 km, then Bancroft at 70 km. The nearest edge is a long way off, so local rules apply throughout.

• Where to Fish on Costello Lake

  There is no published depth for this one, so start shallow and work out. Still water like this holds fish on the edges rather than out in the open. Where the bottom changes texture, fish gather; find that line. Species logged across Nipissing District include smallmouth bass, cisco, yellow perch and pumpkinseed. County data is a starting point rather than a guarantee. On Costello Lake that means starting tight and working out.

• Seasonal Patterns

  Seasonal averages run from -13°C in January up to 18°C in July. Spring and autumn carry the fishing; summer and winter test it. The freeze runs deep into the year, with break-up near late April. Expect the water usable from around late April until roughly late November. The shoulder weeks of the open season are the productive ones. On Costello Lake that shapes the whole year.

• Tackle & Baits

  The paperwork position is blank for this one. Records list it as a natural water body rather than an impoundment. Mapping shows a picnic spot within 810 m. A small crankbait along the drop and a worm in the thick stuff cover the bass. Check locally before you travel, because a wasted drive is a long one. A polite question at the farm gate opens more banks than anything else. For a change of water, Brewer Lake is 1.3 km distant. Treat Costello Lake as unsettled until someone local tells you otherwise.
