**Lake Overview & Access**
Grindstone Lake is a 3,176-acre lake located in Hayward, Sawyer County, offering public boat access via a dedicated ramp. The lake reaches a maximum depth of 60 feet, providing diverse paddling and boating opportunities across its substantial surface area. This is a solid destination for kayakers, canoeists, and motorboaters looking to explore a mid-sized northern Wisconsin lake.
**What to Know Before You Go**
Be aware that user feedback indicates the public boat landing has notable limitations and maintenance issues—plan accordingly and arrive early if possible. The lake is known for clear water conditions, which is excellent for visibility but means fish are more line-sensitive. If you're fishing, note the walleye and muskie populations with specific regulations: a 14-18" slot applies to walleye, with a one-over-18" and one-under-14" keeper limit. Bring lightweight line for clear-water fishing success. This is a popular destination, so expect moderate to busy conditions on weekends.
