Some USGS river gage data fixed... others still out.

The USGS has filled in the data for the Salt River gage. Apparently, there was a "little bit" of a change in discharge from the long-term average discharge values (~23000 cfs vs ~2000 cfs). And with the sudden increase in discharge, it's no wonder that the gage shut down/

However, the Big Muddy River gage at Murphysboro is still in need of correction, and may need to be replaced. (I'm basing this last hypothesis on the fact that there is no current discharge measurement being made at this site.)


I'm not familiar with the White River near Fayetteville, AR, but I assume that it normally runs at a discharge level of slightly larger than the ~1 cfs indicated in its graph. Possibly another indication of an outed gage?

Again, not being situated in the Mississippi River system, I have little opportunity to actually go out and check on the situation of these gages. However, based on news reports, the Kaskaskia river did overflow its banks in Fayetteville during the recent rain storms and flooding in the Mississippi River basin. (I assume that the Kaskaskia and the White converge at some point near the city.)
