Summit Lake (Sudbury District)

Summit Lake (lac Summit) is a lake in geographic Shenango Township in the Unorganized North Part of Sudbury District in Northeastern Ontario, Canada. It is in the James Bay drainage basin about 29 km northwest of the community of Foleyet on Highway 101, and 4 km northwest of the Missonga and 6.7 km southeast of the Oatland railway points on the Canadian National Railway transcontinental main line (used at this point by the Via Rail Canadian service), which runs along the entire west side of the lake.

Hydrology
Summit Lake is about 1.2 km long and 0.5 km wide, and lies at an elevation of 355 m. There are two unnamed creeks as inflows, at the south and northeast tips of the lake. The primary outflow is Shiners Creek, towards Shiners Lake, at the northwest corner of the lake, which eventually flows via the Nemegosenda River, Kapuskasing River, Mattagami River and Moose River into James Bay.
