Au Sable Lake is part of the broader Au Sable River watershed in Ogemaw County. The Au Sable River itself is a 138-mile blue ribbon trout stream flowing southeast to Lake Huron at Oscoda. Reviewers mention back streams connected to the lake that are popular for kayaking, suggesting the lake has flowing connections to the surrounding waterway system.
Au Sable Lake freezes in winter and sees regular ice fishing activity. The DNR launch on the west side provides winter access. Always check ice thickness locally before venturing out — conditions can vary across the lake.

Au Sable Lake sits in Ogemaw County and shares its name with the famous Au Sable River — one of the premier brown trout streams east of the Rockies — though the lake itself is a quieter, more modest destination. There's a single DNR launch on the west side with a dock, vault toilet, and limited parking at the end of a dead-end road. It's used mostly by local residents and has a low-key, uncrowded feel. Kayakers enjoy exploring the back streams and connected waterways, and the lake sees ice fishing activity in winter.
Fishing opinions are mixed — some reviewers report a good variety of fish while others have struggled to find them. The lake is close to several campgrounds including the Rifle River Recreation Area, and nearby Long Lake offers marina services and pontoon rentals if you're looking for more action. Au Sable Lake is best suited for people who want a quiet paddle or a casual fishing trip without crowds.
