First i take it its not normal for this thing to drop this low correct?
My first thought is if that is the case maybe we dug out the river or gave it someplace to go to get ready for a intake of say lots of flooding?
I really dont have a clue. but it is one of my first thoughts
It is not "normal" but it is not unheard of either .
I do not understand why people's minds go to (not you by the way) that it is being drained for fracking or some other nefarious reason . I have worked the rivers for years and have seen them low (or below pool stage) and have ran the rivers during floods when they have left their banks and we have ended up pushing a tow of coal barges through a corn field (my company had to pay the farmer because our boat's rudders left two huge furrows through his field) .
We had a very dry summer and that effects the pools between the locks and dams . Up until recently with all the rain in my area , the creek beside my house was darn near dried up , it is finally running normal once again .
ETA: I think I read that someone was wondering where they measure the depth of the river , for the most part it is measured at each lock and dam , and the Coast Guard will check the depth periodically in the channel to make sure it has not filled in with sand and silt . If one was still allowed to visit the locks and dams on the inland waterways (before 9/11 after which they put a stop to it) , you would see gauges painted on the upper and lower lock walls showing the depth of the river in feet . When I say upper and lower lock wall , what I mean is the upper is the up river side and the lower would be down river side . The pool is the portion of river between each lock , and I have seen the river so low that numbers , below the normal depth , on gauge of the lower lock wall could not be read because it normally stays below the normal pool stage and is covered in algae .
