Boating on Winona Lake in 2026

If you run a motorboat on Winona Lake this season, two laws will shape most of your time on the water. The older one is Indiana Code 14-15-3-17, the statewide rule that holds every motorboat to idle speed within 200 feet of the shoreline. Around Winona, that near-shore band traces a 5.2-mile loop, which this site has mapped in detail on the boating lap page. The newer one is House Enrolled Act 1062, signed March 13, 2026 and effective July 1, 2026. It gives Indiana its first statutory definitions of wake boarding and wake surfing, and it prohibits both between sunset and sunrise on public freshwater lakes.

The other change this season is an engine cut-off switch rule, covered under equipment below. Life jacket requirements, operator rules, and the idle zone carried over from prior seasons. This guide walks through each rule as it applies on Winona, and it keeps legal requirements separate from voluntary stewardship guidance, because the two often travel together in discussion of the new wake law.

The 200-foot idle zone

The 200-foot rule is a state statute, not a local ordinance. Indiana Code 14-15-3-17 provides that "a person may not operate a motorboat within two hundred (200) feet of the shore line... at a speed greater than idle speed." It applies on every public lake in Indiana, and it covers channels as well as open shoreline, so the canals on Winona's northwest side sit entirely inside it.

Idle speed has its own legal definition. Under IC 14-8-2-129, it means the slowest possible speed, not exceeding five miles per hour, at which the boat still maintains steerage and throws minimal wake. In practice that is slower than many boaters assume: if your bow is up and you are trailing a rolling wake, you are past idle even if the speedometer reads under five.

On Winona, the 200-foot line wraps the lake in a loop about 5.2 miles long. The boating lap page draws that loop over the lake so you can see how much open water is actually available at speed, and how narrow the fast lane gets in places. All of the site's maps, including this one and the depth contours, are collected at /maps.

Two details catch people out. First, the line is measured from the water's edge, so it moves with the lake level: after a wet spring the shoreline sits higher and the idle zone reaches farther into the lake. Second, the DNR issues temporary idle-speed restrictions on Kosciusko County lakes after heavy rain. During one of those advisories the entire lake runs at idle, open water included, until the advisory lifts.

Life jackets and required equipment

Indiana's baseline requirement, summarized in the DNR's Handbook of Indiana Boating Laws, is one wearable, U.S. Coast Guard approved life jacket for every person on board or being towed. Vessels 16 feet or longer, other than canoes and kayaks, must also carry a throwable flotation device.

Some activities require wearing the jacket rather than just carrying it. Every person on a personal watercraft must wear one, and so must every person being towed behind a boat, whether on skis, a tube, a wakeboard, or a surfboard.

The engine cut-off switch became a wear requirement this season. As Indiana DNR officers explained in July 2026 coverage, operators of motorboats manufactured in 2019 or later must now wear the cut-off switch lanyard whenever the boat is on plane, so the engine stops if the operator is thrown from the helm. A similar federal requirement has applied since April 2021 to boats under 26 feet on federally navigable waters; the state rule brings the same practice to inland lakes like Winona. If your boat came with a lanyard, clip it to yourself or your life jacket before you throttle up.

One point of frequent confusion is Indiana's mandatory-wear rule for children under 13. That rule applies only on waters of concurrent jurisdiction, such as Lake Michigan and the Ohio River, and does not apply on inland lakes like Winona. State law here requires carrying a jacket for each child, and the wearing decision belongs to the adults on board. The safe practice, and the one this site recommends, is that children wear theirs whenever the boat is underway.

Who may operate a motorboat

For motorboats over 10 horsepower, Indiana gives operators two paths. A person with a valid driver's license may operate one. A person without a license must be at least 15 years old and carry both a boater-education card from an approved course and an identification card issued by the Indiana BMV.

Anyone under 15 may not operate a motorboat over 10 horsepower, and may not operate a personal watercraft. The DNR's boating education page explains the approved courses and how to obtain the card, which is worth doing before a teenager's first summer at the wheel rather than after a stop by a conservation officer.

The new wake law: HEA 1062, effective July 1, 2026

House Enrolled Act 1062, passed in the 2026 session of the Indiana General Assembly, amends the state's boating statutes in a few specific ways. The enrolled act runs three pages, and reading it directly on the General Assembly's bill page takes less time than sorting through the commentary about it.

First, the act defines the sports. Wake boarding means riding a short board, with or without foot bindings, towed by a motorboat across its wake, and the definition covers operating the towing boat as well. Wake surfing means surfing a wake whether or not the rider holds a tow rope attached to the boat producing it, or operating a motorboat that creates a wake that is or is intended to be surfed by another person.

Second, the act adds a new section, IC 14-15-3-8.1: "An individual shall not operate a motorboat on a public freshwater lake for the purpose of wake boarding or wake surfing during the period between sunset and sunrise." Violating that section is a Class C infraction.

Third, on the small lakes already held to Indiana's statewide 10 mph limit, wake boarding and wake surfing are now allowed only during the time and day of a granted speed exemption. Winona, at about 570 acres and classified as a high-speed lake, is well outside that category, so this provision does not apply here.

The act sets no distance-from-shore requirement for wake sports and no minimum operating depth. The 500-foot and 20-foot figures that circulate alongside the law come from University of Minnesota research recommendations, quoted in The Watershed Foundation's explainer, and they are not provisions of Indiana law. TWF's lake-by-lake summary lists Winona among the high-speed lakes where the practical change is the nighttime prohibition: daytime wake surfing remains legal here, and the difference boaters will notice is that sessions now have to end by sunset.

Beyond the law: depth as a voluntary choice

Because HEA 1062 says nothing about depth, the choice of where to surf on Winona is left to boaters. This site's guidance is to keep wake sports over water at least 20 feet deep. That figure is a voluntary judgment call rather than a published standard, and the boating lap page labels it exactly that way. The reasoning is physical: a ballasted wake boat pushes energy downward, and in shallow water that energy stirs bottom sediment along with the phosphorus bound to it, which feeds algae.

The deep water is mapped. About 319 acres of the lake, mostly the central basin, sit at 20 feet or deeper, and the depth page shows the contours from the DNR's 2017 bathymetric survey. Along parts of the east shore the 20-foot contour comes within about 110 feet of the bank, which is inside the legal idle zone, so the practical surfing area is where the deep water and the water outside the 200-foot loop overlap.

Industry guidance points the same direction. The Water Sports Industry Association's Wake Responsibly campaign asks surfers to stay 200 feet from shore and docks, keep music at a reasonable volume, and avoid repeated passes along the same stretch. It publishes no depth figure. For the longer version of the voluntary case, including how the 20-foot line was drawn, see the responsible wakes article.

Check conditions before you launch

The rules stay put all season, but conditions change daily. The Lake Today page shows current weather, a five-day forecast, and a watersports score, and weather.winonalake.org carries the hourly forecast. A quick check matters legally as well as practically after storms, since the DNR's temporary whole-lake idle advisories on Kosciusko County lakes tend to follow heavy rain. Confirming the lake's status before you trailer over spares you the trip that ends with the whole lake at idle.

Before you go

The working checklist for a 2026 outing on Winona:

• Idle inside 200 feet of shore. The line moves with the lake level, and the mapped loop is at /boating-lap.
• Life jackets: one wearable per person, a throwable on boats 16 feet and up, and everyone towed or on a PWC wears one. Children should wear theirs too.
• The driver: licensed, or at least 15 with a boater-education card and BMV ID, for anything over 10 horsepower.
• Clip the cut-off lanyard. On boats built in 2019 or later, wear the engine cut-off switch link whenever the boat is on plane.
• Wake sports end at sunset. HEA 1062's prohibition runs from sunset to sunrise, and violations are a Class C infraction.
• If you surf, favor the mapped 20-foot water. The law does not require it, but the lake benefits from it.
• Check /lake-today before leaving the house, especially after heavy rain.

Most of this list needs checking once a season. Conditions are the exception, and they are worth a look every trip.
