Hydrology
Cross Lake is in the Saint Lawrence River drainage basin, is about 3.6 km long and 2.3 km wide and lies at an elevation of 441 m. The name refers to its roughly cross-like shape, with one line running from the northwest to southeast, and the other from west-southwest to east-northeast.

There are four unnamed creek inflows, one at the west, one at the south, one at the north from Lyell Long Lake and one at the southeast from Hawk Lake. The primary outflow, at the southwest, is Moore Creek towards McKenzie Lake, which flows into the Madawaska River, and via the Ottawa River into the St. Lawrence River.
