About the water

6,800-acre reservoir on the Wisconsin River gives plenty of space; less crowded than southern resort lakes.

Wisconsin wake-sport rules

Wisconsin has no statewide wakesurfing-specific law as of mid-2026; competing bills remain unenacted. Proposals include AB 1033 (200/300-foot setback, no depth limit; Assembly-passed) and SB 1024 (500-foot setback and 20-foot depth). In the absence of statewide rules, towns have adopted local wake-surf bans (e.g., Lake Waramaug-style ordinances and Waupaca/Long Lake actions), some of which are being litigated. Limits are currently local/waterbody-specific.

This rating classifies measured depth and surface area against published wake-sport guidance. It is not a safety clearance and not permission to ride: local no-wake zones, hours, and horsepower limits are set by the county, lake district, or land manager, and they take precedence.

This is a read of the water's dimensions, not legal permission — check the Wisconsin rules and the local authority for this lake before you launch.

No maximum-depth measurement is on record for Lake Dubay in the state agency data we use, so its depth factor is unrated. We do not estimate depth.

Lake Dubay carries a LakeQuality water-quality grade of D, computed from EPA and state monitoring data — Secchi clarity, total phosphorus, and chlorophyll-a. That is a separate question from wakesurf suitability: a lake can be excellent to ride and mediocre to swim in, or the reverse. See the full lake page for the grade breakdown.

Wisconsin has no statewide wakesurfing-specific law as of mid-2026; competing bills remain unenacted. Proposals include AB 1033 (200/300-foot setback, no depth limit; Assembly-passed) and SB 1024 (500-foot setback and 20-foot depth).

Limits are currently local/waterbody-specific. Individual lakes often add stricter local limits on top of the statewide rule — no-wake zones, operating hours, and horsepower caps are all common — so confirm with the local authority for Lake Dubay.
