Why didn't the Louisiana Territory receive as much settlement as other parts of the US did?

What year do you see as the crisis point in regards to this?
To my recollection (not looking at any data before responding) either 1995 or 1996 was the end of a series of wetter summers in the West, so already the length of this dry cycle is notable, at almost 25 years.

There's public data about the depth of the reservoirs along the Colorado river system. Just draw a trend line on the depth of these reservoirs and I do believe that the Colorado is in "zero margin" in less than 15 more years (but I need to have this guesstimate checked...).
