Day 129: Nonlinear


Coffeeville Lock and Dam

It's hard being a river neophyte.  Yesterday's water level predictor line was nice and straight.  Extrapolating it showed that the water level would be at 12', the ideal height for our trip north, this Friday.  Today's graph shows the error of my way.  Rather than straight the predictor line is nonlinear.  Worse, it appears asymptotic about 17'.  So, the predicted water level will never reach 12'!  

We may be spinning our wheels waiting at this time of year.  I'll do some historical research on Coffeeville's gage height and get back with the results tomorrow.


A Well Marked Fairhope Trail

We were enjoying the hike until we came across this sign.

Still in Fairhope, Alabama and at 945nm.  DBH
