Suspended Sediment Comparison of
Developed and Undeveloped Drainage
Basins in Humid Mountainous Terrain:
Stowe, Vermont
Toby Stegman
Mikhail Romanoff
Project Goals
Compare similar drainage basins on Mount
Mansfield.
Measure Total Suspended Solids (TSS)
Compare results to decipher the effect of
Stowe Mountain Resorts development
Study Location
Methods
Collect water samples in 5 gallon
buckets Two storm events - one normal
flow
Evaporate water
Weigh bucket with and without (TSS)
Compare and contrast results to
precipitation and flow data
Write paper
Precipitation and Flow Data
October
Data
Discussion
Notch Brook shows a higher (TSS) concentration
Direct correlation of (TSS) with stream flow
Increase flow, Increase (TSS)
Clear cutting and urbanization increases (TSS) as
well as surface runoff
High (TSS) is detrimental to fresh water fisheries
Increased (TSS) decreases the capacity of the
Waterbury Reservoir
Conclusion
Stowe Mountain Resort’s development is a
key source of increased (TSS)
New development is planned at Stowe,
including 135 acres of trails, and hotels
Careful planning should be taken by
developers at Stowe to reduce
environmental impacts
