Does not prevent flooding - prevents the need to close the line due to flooding
Do you know enough about this project to be able to say that definitively? If a railroad line is at a certain level,
it may block the flow of waters. By raising it via a higher bridge or trestle, it could allow water to flow unimpeded,
thus preventing a flood. I don't know if that's true in this case, I'm only pointing out that possibility.
In any case, to all but hydrologists, high waters are considered a "flood"only when they start causing damage to property or
infrastructure. If this project prevents high water from damaging the tracks, you might indeed say it is preventing a flood.
I've not seen any reference to high Devils Lake waters threatening houses or other property. If the tracks are safe, then
is it really a "flood"?
I guess you're not aware of the issue. Devils Lake is in a closed basin. The water checks in, but it doesn't check out. As a result, the water keeps rising.
The line is not being raised to prevent the tracks from being subject to periodic flooding. The line is being raised to prevent it from being permanently submerged and abandoned (which would prevent Amtrak from serving Grand Forks).
I realize you're making a hydological point about Swadian's statement. I don't think Swadian was saying that they were raising the line to prevent flooding (as in a levee), but that they were raising the line to prevent *it* from flooding. Anyway, Johnny was making the point to Swadian that the line is not subject to temporary floods, but that it will actually be permanently flooded.
The upgrade project will raise the level of the tracks to 1,461 feet above sea level. At 1,458 feet above sea level, Devils Lake will spill into the Sheyenne River through a coulee, something it hasn't done in about 1,000 years. The lake's current elevation is at 1,454.2 feet above sea level. The tracks were about a foot above the water line before the track raising project started.
