How A Mill Works - The Wheel House

Introduction

- counties

chosen for

varying

geography

-painting of

mills, dams,

and ponds


Mill frequency and sediment load in bennington caledonia and chittenden counties vermont

Methods

• Looked for mills on Walling’s maps, 1856 - 1858

• Calculated mill frequency for each town (per square mile)

• Looked for relationship between mill frequency and

population and relief

• In the field, we looked for sediment deposits behind

former mill sites and other evidence of landscape change

Sample Town – Woodford, 1856

Population:

423

Mills:

20 saw mills

(orange)

4 ocher mills

and 1 oil mill

(pink)

Area:

123.28 sq. km

Mill Frequency:

.2028 mills/sq. km

(highest of towns

sampled)

Results

-predominantly saw mills

-mill frequency

Bennington 0.03 /sq km

Caledonia 0.03 /sq km

Chittenden 0.02 /sq km

Results

Affect On Stream Path

Upon Removal Of Dams

1857

Jericho

1996


Conclusions

Conclusions

  • Higher mill frequency was found in mountains with higher average slope and less population density.

  • Sediment trapped behind dam was likely transported downstream after the destruction of the dam.

  • Change in Browns River displays the impact humans have on landscape change as far as the construction and destruction of dams
