River mile = road mile ???

Depends on what you mean. Rivers have current, so if you are talking about the distance your boat has moved relative to the shoreline, or the distance your boat has moved in the water, the answer will be different.

Wouldn’t 5280 feet on water be the same as 5280 feet on land??

YEP, walking or riding
July 18, 2011 at 5:37 pm #981796Like all the above and JJ’s link, a river mile is the same as a road mile…
What confuses some is that on the Mississippi Mile Marker 844 (near Hastings) is not 844 miles from the Gulf. It’s 844 miles from the mouth of the Ohio River/St Louis River.

July 18, 2011 at 6:20 pm #981802I think there are two potential points of confusion that might warrant someone asking the question in the first place.
The first is if the person is confusing nautical miles with Si miles. A nautical mile is 1.15 si miles and is often used in marine and aviation. Now, the fact remains a nautical miles is 1.15 miles whether on land or sea but is more often used at sea and seldom used in every day speech. This might lead to some confusion.
The other area is what someone alluded to and that is relative to land or the water itself. This would show up if you were to compare a GPS mile to a mile somebody measured using a paddle wheel type sensor. In that case, the mile would read differently, but only because GPS is relative to a point on earth and the paddle wheel is relative to the water which is already moving. As mentioned, a mile is 5280ft either way you slice it. Its just a matter of 5280ft relative to what.

Correction, Ohio and Tennessee Rivers meet with the ‘sippi.
July 18, 2011 at 7:57 pm #981830If you really want to add confusion to this discussion, use your GPS to find 45 degrees north latitude–roughly the osprey nest at the south border of Bayport, MN on the St. Croix river. (Also Broadway Ave in Minneapolis, the north borders of Wyoming, Vermont, and Jellystone National Park, as well as Salem OR,home of Pendleton shirts and blankets)
CAUTION: this is NOT halfway to the north pole, since the Earth is an Obloid (flatter at both poles) Halfway to Santas Workshop is somewhere up near Marine-on-St.Croix, about 11 miles away. Look for the cow standing next to the Mistletoe bush with red and white ribbons on her horns. About 100 yards offshore at the osprey nest theres a pretty good walleye bump so be sure to mark the location on the side of your ice house next winter.July 19, 2011 at 8:01 am #981974Helped me,
I don’t mean to hijack this thread but……I had a dissuccion at Mille Lacs last month with 2 boat mates about “Right return red” when navigating rivers. Made me remember how it goes.
Basically when going upstream, navigational marker buoys that are red should be on your right and the green ones on your left.
When headed down stream “Green is the Right way to go” back to sea.
I’m not on navigational rivers much at all anymore and it has been hard for me to remember.

That’s it Denny, at least for the Great Rivers.

Unless you are on the St. Croix, then it is the opposite. At least that is what a lot of the pleasure boaters believe.
