How long will the Great Lakes last?

At the current rate of sediment accumulation in lake Erie, it would accumulate enough fine grained material to fill its volume in less than 70,000 years.

This assumes a lot i.e that we wouldnt dredge material, that something else doesnt wipe them out first etc.
Until they become the Alright Lakes.
- This is askscience. We need a standardized scale for this.
  
  Great should obviosly be near the top. But is Ok above or below Alright?
  
  Point taken. I'd suggest something along the lines of this scale:
  
  great > good > alright > ok > adequate > meh > fair > subpar > unfortunate > abysmal
So you mean like if the ocean dissapears?
Last?

Are they going away?
- I mean most things do eventually
42
- Seconds? Years? Decades? Meters? AU?
  
  Care to give a unit?
  
  It's a joke. It's a reference to Hitchhiker's Guide to the Galaxy where the answer to the ultimate question is 42. It's designed to not make sense.
  
  The unit is 42
