The scenarios cannot consider every uncertainty associated with an actual flood event. In short, these are not the only scenarios possible, but allow for planning degrees of response. The maps do not take into consideration work being done along the river in regards to levee fortification and again may not accurately reflect inundation.

Still, the maps provide useful information, and we hope to use them in an interactive “depiction” very soon.

Another useful tool is from the NOAA, a page showing current & forecast river levels at the Auburn gage. This can be used in coordination with the Corps maps, which are based off of measurements at the same location–for example, their lowest flood scenario is 13900 cubic feet per second (cfs) at that part of the river. At the moment, the river is at about 1400 cfs (or 1.4 kcfs), and isn’t expected to get higher than 2000 cfs in the next few days.

We’ve put all four of these maps into a single “depiction,” so you can examine and compare each of them.

The rains are here; but, forecast will not cause Green River Valley flood concerns. Check out where the weather is http://tiny.cc/erRj7

Most importantly, Rep. Dave Reichert has a great site up with links to many useful sites, both specifically about the Howard Hanson Dam situation and about preparing for floods in general. (He does not, for some reason, have any links to this site!).

Also, a slightly less official site has appeared. “Hansondam.com” looks suspiciously familiar, providing “news and information about Howard Hanson Dam.” It’s been set up, if not very prettily, by what are no doubt good folks at SandBagsToGo.com. So, if you need sandbags to go, you know where to get them
