Thousands of Ohioans are taking to the rivers and lakes of the Buckeye State for recreation. Summer is also the peak working season for those who make a living on or near Ohio’s many waterways.
More people on and near the water increase the risk of injury. From those who visit the water for recreation to those who make the water their career, everyone has a right to use Ohio’s precious natural resources safely, hence the need for essential safety tips and best practices for a safe summer season.
Ohio’s Lake Erie, Inland Lakes, and Rivers
Ohio has more freshwater than most realize. According to the Ohio Department of Natural Resources, Ohio is home to 110 natural freshwater lakes that are five acres or larger. Ohio’s natural lakes can be found in 21 counties, and most of them formed from either glaciers or by meandering rivers that created oxbow lakes.[1]
Ohio also has 172 human-constructed reservoirs that are greater than 25 acres. In fact, the total acreage for reservoirs across the Buckeye State comes out to about 130,000 acres. When the Ohio Department of Natural Resources adds private and public ponds and smaller human-made reservoirs to the list, the state will have over 5,000 lakes, reservoirs, and ponds.
Ohio is also home to more than 3,000 rivers and streams, totaling about 29,113 miles of waterways. Some of the major waterways most used for commercial activity and recreation include the Ohio River, Scioto River, Great Miami River, Maumee River, and Cuyahoga River.
Last but not least, Ohio claims 316 miles of Lake Erie shoreline, the 11th-largest lake in the world by water surface area. These waterways provide natural beauty and resources to Ohioans when they work and recreate. Unfortunately, thousands of Ohioans also injure themselves on or in the water each year, and according to the Ohio Department of Health, the state consistently ranks high in the nation for unintentional drownings.[2]
Obstructions: What to Watch for Above the Water
Ohio’s waterways receive significantly more traffic and use in the summer, typically in the form of recreational boating, commercial shipping, swimming, small watercraft use (kayaks, canoes, paddle boards), float plane use, tow sports, fishing, scuba diving, or snorkeling.
Above-water health hazards one must constantly be on the lookout for include:
- Commercial freighters
- Other watercraft
- Swimmers
- Fixed hazards
- Diver-down flags
- Channel markers
- Floating debris
- Algae blooms
- Fishing line and tackle
The Biggest Above-Water Risk is the Weather
Whether one is working or recreating on the water, physical obstructions may be the most apparent health hazard, but all physical hazards combined are dwarfed by one other above-the-water factor: the weather.
According to the Ohio DNR, inclement weather is the leading cause of water-related emergencies in the state. Summer’s warm weather shifts the northern hemisphere’s weather patterns, making thunder, windstorms, and hurricanes more likely. In fact, weather-related risks are so severe on Lake Erie and throughout the Ohio River Valley that the Ohio DNR released a “Weather or Not to Boat” PSA to inform the public about safe boating practices during inclement weather.[3]
The Hidden Danger: What to Watch for Below the Water
In the first few months of 2026, much of Ohio experienced severe to extreme drought conditions that affected groundwater aquifers and surface water levels in rivers and lakes across the state. Recent moisture has helped most water systems return to normal throughout Ohio’s 88 counties, but the dangers one may encounter beneath the water’s surface remain.
What do we mean by this? When boating, whether for recreational purposes or for commercial shipping or fishing, one may encounter an obstruction or obstacle submerged below the surface, low enough that it cannot be seen with the naked eye, but close enough to the surface that one’s vessel may run aground on it. These dangers are more prominent when water levels are low, but they are always there and pose some risk, no matter the water levels.
Boaters must always proceed with caution, observe all speed limits, and ensure all radar and sonar equipment is in working order to avoid such obstructions.
Flood Risk is Also a Factor to Consider
Ohio’s meteorologists have reported an uptick in flooding throughout the state, and while only 6.9% of the state is in a flood zone, the Ohio Emergency Management Agency recently reported that flooding is now the state’s most common natural disaster.[4]
What does this mean for people who are recreating on or near the water?
The safety tip is simple. When relaxing or camping near a body of water, always set up camp above the hundred-year high-water line. When recreating at DNR-managed sites, DNR staff should have information on flood-safe zones where one can still enjoy the water while staying safe from the risk of an overnight flash flood.
Waterborne Illnesses
The Ohio Department of Health BeachGuard program was established to warn the public about the health risks associated with waterborne illnesses caused by harmful algal blooms and other contaminants. These are especially prevalent in the western basin of Lake Erie and in major rivers such as the Ohio River and the Maumee.
The two illness-related issues to watch out for most are cyanobacterial (blue-green algae) contamination and E. coli contamination. BeachGuard utilizes a flag system to warn of bacterial contamination at beaches and rivers. The system’s website also maintains up-to-date information on the health of Ohio’s lakes and rivers.[5]
Hypothermia and River Currents
Last but not least, Ohioans who work or play in or near the water this summer need to be mindful of the risk of hypothermia from cold-water immersion. They also must be aware of dangerous river and lake currents.
Ohio summers may be getting warmer, but that doesn’t mean the water will warm up as quickly or to the same degree as the air will. According to the Ohio DNR, even in late spring or fall, water temperatures below normal body temperature (98.6°F) tend to cool the body about 25 times faster than air does.[6]
And while hypothermia risks decrease during summer, prolonged exposure to even “warm” water can increase risk for body cooling and potential hypothermia. Boaters, swimmers, and workers must limit their exposure to the water and, if they must be in it for extended periods, wear protective equipment such as a wetsuit.
Even on calm days, Ohio’s rivers, inland lakes, and Lake Erie can have dangerous, invisible currents that one may not be aware of until it is too late. Breakwaters, piers, jetties, and river mouths create fast-moving currents in the water that cannot be seen or heard; they can only be felt.
Particularly in southeastern Ohio, higher-elevation areas can produce fast-moving river currents that are difficult to navigate without professional training. People working or recreating in or near the water must be aware of their surroundings, the weather, water conditions, and the specific factors influencing that body of water’s behavior.
