Butterfield Creek at 05536255

 23.5 m2  Highly Urban ; ~80% Urban/20% open land, lots of urbanization in last 20 years  

Gentle slope overall, ~1% across watershed, high points on SW continental divide


ENE, overall  eastward falling slope

 Silurian Bedrock underlies area, Moraine till, floodplain,and  lake sediment surficial deposits  variable with most being silty. Group C soils
