the 1997 red river flood rose 9.2 feet!
7 feet
40 feet
The Olentangy River is normally only around 2 to 3 feet deep. If the river gets to be 13 feet, it is at flood stage.
it got to be 14 feet at its highest point
"the historical flood event of Nov. 5, 1985, which produced a river crest at Charleroi, Pa., 14.7 feet above flood stage." If the web is to be believed, it appears that it has in the past.
The Amazon River does flood and it usually starts in November. The river floods every year and can swell up to 25 miles and tripling the land area it cover.
The reason is very simple; Tewkesbury council decided to let builders build houses on the flood plain area of the river about 15 years ago. They and Severn Trent water stopped dredging the river system at about the SAME time. The river should be 40 feet deeper here at Tewkesbury Wharf but is only 11 feet deep! So the houses flood EVERY YEAR. Because the council are NOT very practical in coming up with a plan to re dredge the river for about 1 mile each side of the town, the town itself will continue to flood! Its ain't rocket Science is TBC??
"Crest" means the highest the water level is expected to get. "Flood stage" is the water level where the river is over it's banks, hence "flooding". A river can crest below, at, or above it's flood stage. It can crest three inches above flood stage (innocuous) or fifteen feet above flood stage (a disaster). Or anywhere in between. Or below flood stage. Every river, every spring, is different.
The depth of the Patoka river (which I assume means average depth) depends on which day you measure. von Stienwehr recorded a max depth, in 1874, at 30 feet. The flood stage today is 18 feet. Somewhere in between those two numbers lies the "true depth" of the Patoka river. Pick a number...
It is 738 feet above sea level
Cincinnati is on the northern shore of the Ohio River. Kentucky is south of the Ohio River, so in gneeral terms the Ohio River separates Cincinnati, and all of Ohio, from Kentucky. More specifically, however, the Ohio River is within the boundary of Kentucky. In most cases, where two states are separated by a river, the border is set in the middle of the river. In the case of the Ohio River, The Commonwealth of Kentucky extends to the northern low water mark of 1793 (Supreme Court Ruling)-or about 80% across the river, so the river belongs mostly to Kentucky. The U.S. Supreme court ruling that established the line was done for several reasons, mostly because Kentucky objected to an Indiana nuclear power plant that would discharge into the Ohio River. But also because if the high water mark were to be used, half of downtown Cincinnati would fall under the jurisdiction of Kentucky thanks to the 1937 flood which reached 80 feet, 55 feet above current average height, or 28 feet above current flood stage. As recently as 1997 (7 years after the Supreme Court ruling that set the boundary line at the 1793 low-water mark) the local running joke during the 1997 flood was that the whole Cincinnati Riverfront Stadium problem and the proposed structure that would become Great American Ballpark and Paul Brown Stadium were Kentucky's problem now.
Well, it depends on how large the storm surge. I have seen water rise 10 feet from a river during a storm surge. It also depends on lake or river, because of if it is moving water or still water.
