Its surface is generally frozen from the beginning of December to the end of April.

This body of water is relatively parallel and on the west side of the Capousacataca River.

The mouth of this lake is located at the bottom of a northeastern bay 7.4 kilometres (4.6 mi) north of the confluence of the Capousacataca River with the Mégiscane River; at 53.8 kilometres (33.4 mi) north-east of the confluence of the Mégiscane River with Parent Lake (Abitibi); to 40.7 kilometres (25.3 mi) north of the Canadian National Railway's Paradise Station and 64.7 kilometres (40.2 mi) northeast of Senneterre.

The name "Lac Valets" was officialized on December 5, 1968 by the Commission de toponymie du Québec when it was created.
