Streamflow
Below Normal in State Rivers
Streamflow in central New Hampshire and Vermont
is generally below normal, a situation that has been growing worse
since mid-July according to the U.S. Geological Survey. "At
many stream-gaging stations in the area, flows are between 25 and
35 percent of their normal range for this time of year" said
Ken Toppin, Chief of the Surface Water Section of the USGS District
Office in Pembroke, NH. "Out of 50 streams and rivers that
we monitor on a long-term basis, 34 have flows less than half of
normal for this time of year, and 15 have flows that are less than
one-third of normal" said Toppin. In 14 streams, flows are
below the weekly amounts that occur only once on the average every
10 years. According to Toppin, the lowest streamflows are occurring
primarily in the Pemigewasset, Merrimack, middle Connecticut, Lamoille
and Winooski River Basins. The table below summarizes flows at some
of the USGS gages on large rivers in these basins. For more information,

As the nation's largest water, earth and biological
science and civilian mapping agency, the USGS works in cooperation
with more than 2,000 organizations across the country to provide
reliable, impartial, scientific information to resource managers,
planners, and other customers. This information is gathered in every
state by USGS scientists to minimize the loss of life and property
from natural disasters, contribute to the sound conservation, economic
and physical development of the nation's natural resources, and
enhance the quality of life by monitoring water, biological, energy,
and mineral resources.
