What is the speed of the current in the Niagara River?

The speed of the current in the Niagara River varies depending on the specific section being measured, but generally, it can reach speeds up to 2.2 mph. This current is influenced by the substantial flow of water coming from Lake Erie toward Lake Ontario, particularly as it passes through the Niagara Gorge where the water accelerates due to the gradient of the riverbed.

On the other hand, other options may not accurately reflect the typical current speed observed in the river. For instance, 1.0 mph might be too low for the measurable speed of the current, especially in areas closest to the falls where the flow is significantly stronger. Speeds like 3.7 mph and 4.6 mph might also exceed the general flow rate, as these figures are more representative of faster flowing sections during certain conditions, but they are not the standard for most navigable areas in the river. Understanding the dynamics of the Niagara River's flow is essential for navigation and safety, making 2.2 mph a more reliable average for current speed assessments.
