We need your help identifying water withdrawals

As Vermont potentially enters a drought due to the ongoing dry weather over the past several weeks, there is rising concern about the impacts on the water levels of our lakes, rivers, and streams.

 

New and increasing surface water uses and the uncertainties of climate change make reliable natural flows and sustainable lake levels more important than ever to protect aquatic habitat for fish and invertebrates.

 

With this, we are asking our members to notify us if you see one or more water withdrawal pipes while you are out on your walks, boating, birding, or fishing. Please keep track of them and note the general location of the withdrawal and the size of the pipe and send the information along to David Deen at strictlytrout@vermontel.net .

 

Just for reference if you see a pipe taking water from a stream you can get an idea of how much water is withdrawn using the chart below:

 

Estimated Pipe flows:

  • 1/2” pipe = 14 gpm = 840 gph = 20,160 gal/day = .03 cfs
  • 1” pipe = 37 gpm = 2,200 gph = 53,280 gal/day = .08 cfs
  • 2" pipe = 127 gpm = 3,048 gph = 73,152 gal/day = .28 cfs
  • 4" pipe = 480 gpm = 28,800 gph = 691,200 gal/day = 1 cfs
  • 8” pipe = 1,600 gpm = 96,000 gph = 2,304,000 gal/day = 3.5 cfs

Thanks
