**Overview**
Grindstone Lake is a large 3,176-acre lake located in Hayward, Sawyer County, offering public boat access via this designated ramp. The lake reaches depths up to 60 feet, making it suitable for various watercraft including kayaks, canoes, and motorboats. This is a popular destination for fishing enthusiasts targeting walleye and muskie.
**What to Know Before You Go**
Be aware that user feedback indicates the public boat landing is in poor condition, so plan accordingly and proceed cautiously when launching or loading. The clear water makes this an excellent fishing spot but requires appropriate tackle and technique. If you're fishing, note the walleye slot limits: keep only one fish over 18 inches and one under 14 inches.
**Practical Tips**
Secure all loose items before launching and loading—the ramp conditions mean extra care is needed during these transitions. Bring lightweight fishing line if angling, as the lake's clarity demands finesse. This is a substantial lake suitable for day trips and extended paddling, with depths allowing exploration throughout the water body.
