Squally, thundery weather in the area today, with a mirror surface most of the day and pressure going nowhere. The fish at Grass Lake are likely to sit near structure within a cast of the bank. A tough forecast; the middle of the day offers the only real chance. Keep baits small and presentations quiet.

Grass Lake sits within Sudbury in Ontario. It stands 434 metres above sea level. Surface area runs to about 8 hectares — small enough to read in one session. It is one of the smaller waters we list in Sudbury. Chapleau is the closest place, 39 km off. The big place round here is Greater Sudbury, 275 km distant. Also within reach: Lily Lake within 2.2 km, Madge Lake 2.8 km away, Slee Lake within 2.9 km, Burnt Lake 2.9 km away and Pilot Lake within 3.3 km. One jurisdiction covers this water end to end.
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. Species logged across Sudbury include smallmouth bass, northern pike, yellow perch and Iowa darter. The county list is broader than any single water. Grass Lake responds to conditions more than to tactics.
Long-term averages put July at about 16°C and January near -16°C. Little of the calendar is open water, so timing counts for everything. Firm cover through the cold months, then open water from early May. Average temperatures cross freezing around early May in spring and again near mid November in autumn. The first weeks of open water and the last are the ones to plan for. That shapes the year on Grass Lake.
Public sources are silent on who controls the bank. We find no slipway, car park or made path within a short radius, so treat access as rough. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Where a permit is needed, the nearest town usually sells it. Access can change hands, so last year's answer may not hold. For a change of water, Lily Lake is 2.2 km distant. The position on Grass Lake is worth confirming on the day.
