School:

University of Vermont

Watershed:

Lamoille Basin

River:

Monitoring Site:

Lamoille River and Lake Arrowhead

Site Description:

Lake Arrowhead is a man-made lake affiliated with Arrowhead Dam.

Surrounding Development or Land Use:

Residential

Factory

Forest

Road Along Bank

Do you see any pipes entering into the river?:

Is there a water treatment plant upstream?:

Canopy Cover:

0-25%

Water Appearance:

Clear

Green

Tea-colored

Water Odor:

Odorless

Average Embeddedness:

26-50%

Average Velocity:

0.00m/s

Physical Summary:

There was very little canopy cover at the lake Arrowhead site. Most of it was wide open. It had rained the night before our visit and was tough to get an accurate reading of the embeddedness at the station where we were at. Our school is listed as UVM but we were Milton Middle School. I didn't see it in the drop down box.
