2. The Mt. Mansfield paired-watershed study

3. How does alpine development affect hydrology?

4. Water yield responses due to forest harvesting in the Eastern U.S.
Comparison to other paired watershed studies in Eastern US
This graph represents the change in water yield between pre-forest harvesting and the first year after forest harvesting.
Other study locations include Hubbard Brook, Marcell, Fernow, Leading Ridge
The x-axis displays the percent forest area cleared and the increase in water yield after harvesting is on the y-axis

5. Annual Runoff Comparisons
Ground breaking on Spruce Peak development begins, late summer 2003
Water yield discrepancy bar graph
This graph represents the differences in water yield between the two basins from water year 2000 through 2006, where West Branch consistently exceeds the yield of Ranch Brook.
The water yield differences range from 18 to 36 %
Note: Snowmaking only represents 3-4% of the precipitation

7. Does rainfall explain water yield differences?
Summer 2002
Precipitation data for RB and WB
Trends in rainfall in millimeters with elevation
No difference was determined between rainfall precip-trends between these two basins
Summer 2003
Data from Mills, 2004 (unpublished thesis)

8. Does snow explain water yield differences?

9. study motivation
How does recreational development in NE mountainous terrain impact the environment?
Specifically, how do ski resort developments affect the hydrologic cycle?
Forests in New England are under pressure due to increases in development and population
