    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.

        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.
