Deep thought

If you thought the potholes were bad last year, wait until you see what this round of precipitation and freeze/thaw cycles brings in a month or so.

  • Hey, look on the bright side. The reservoirs are over-full and the ambient flows in the Falls and Little Rivers are well above median.

  • Yep - i'm even flushing my toilet regularly to try to create some room in the reservoir for the extra runoff.

  • Actually, 2 additional thoughts.

    As i understand it, it's not the quantity of precipitation, but the freeze/thaw cycle that eventually expands micro-fissures into potholes. Not that i have anything against potholes, your best traffic calming value.

    Also, during the drought one thing that became apparent is that our rainfall patterns have changed over the past hundred years or so. Overall rainfall is only down about 10% annually or so, but the month-by-month distribution is pretty different. We have much more of a wet/dry season pattern now than we did for most of the 20th century.

    No idea if this is a permanent change or not, but if it is, it has serious policy implications for both water supply management and flood control issues.
