Bovine excrement.  Do I need to make an exhaustive list of the 
water-feature nonsense I keep finding?  Lakes dry up, and rivers change 
course (especially around Calgary in 2013).  Somebody imported a whole 
swath of ponds and lakes in NE Alberta, where a glance at imagery shows 
few if any still exist; it's all farmland now.

CanVec gets shat upon because the data quality is shite.  You can put 
water features in the BAD column along with landcover, POIs (schools are 
not prisons), trails (approximate is not good enough), and so on.

I am part of the CanVec immune system, because I want to see us create a 
*quality* map.
